+
+## 🤖 Agent Guidelines
+
+### Before Making Changes
+
+1. **Understand the Context**
+   - Read relevant documentation in `docs/`
+   - Check `TODO.md` for current priorities
+   - Review `SECURITY_AUDIT.md` for security considerations
+   - Check `ROADMAP.md` for feature direction
+
+2. **Check Existing Patterns**
+   - Look at similar existing code first
+   - Follow the established patterns in the codebase
+   - Don't introduce new patterns without good reason
+
+3. **Identify Dependencies**
+   - Check if your change affects multiple modules
+   - Ensure you understand the Celery task flow
+   - Consider impact on database schema
+
+### Code Conventions
+
+#### Python Style
+```python
+# Use Black formatting (line length: 120)
+# Use type hints
+def process_document(file_path: str, metadata: Dict[str, Any]) -> DocumentMetadata:
+    """
+    Process a document and extract metadata.
+    
+    Args:
+        file_path: Absolute path to the document file
+        metadata: Additional metadata to include
+        
+    Returns:
+        DocumentMetadata object with extracted information
+        
+    Raises:
+        FileNotFoundError: If file doesn't exist
+        ProcessingError: If processing fails
+    """
+    pass
+
+# Use descriptive variable names
+user_document_path = Path("/workdir/documents/invoice.pdf")
+ocr_result = extract_text_from_pdf(user_document_path)
+
+# Prefer explicit over implicit
+if storage_provider == "dropbox":
+    upload_to_dropbox(file_path, metadata)
+elif storage_provider == "google_drive":
+    upload_to_google_drive(file_path, metadata)
+else:
+    raise ValueError(f"Unknown storage provider: {storage_provider}")
+```
+
+#### Configuration
+```python
+# Always use settings from config.py
+from app.config import settings
+
+# Good
+api_key = settings.openai_api_key
+
+# Bad - never hardcode
+api_key = "sk-abc123..."
+
+# Check if optional services are configured
+if settings.dropbox_app_key:
+    # Dropbox is configured
+    upload_to_dropbox()
+```
+
+#### Error Handling
+```python
+# Use appropriate exception types
+from fastapi import HTTPException, status
+
+# API endpoints should return HTTP errors
+@router.get("/files/{file_id}")
+async def get_file(file_id: int):
+    file = get_file_from_db(file_id)
+    if not file:
+        raise HTTPException(
+            status_code=status.HTTP_404_NOT_FOUND,
+            detail=f"File with ID {file_id} not found"
+        )
+    return file
+
+# Tasks should log and handle errors gracefully
+@celery_app.task(bind=True, max_retries=3)
+def process_document_task(self, file_path: str):
+    try:
+        result = process_document(file_path)
+        return result
+    except TemporaryError as e:
+        logger.warning(f"Temporary error processing {file_path}: {e}")
+        raise self.retry(exc=e, countdown=60)
+    except PermanentError as e:
+        logger.error(f"Permanent error processing {file_path}: {e}")
+        # Don't retry permanent errors
+        return {"error": str(e)}
+```
+
+#### Testing
+```python
+# Mark tests appropriately
+@pytest.mark.unit
+def test_hash_file():
+    """Unit test for file hashing utility."""
+    pass
+
+@pytest.mark.integration
+def test_upload_api_endpoint(client):
+    """Integration test for upload API."""
+    pass
+
+@pytest.mark.requires_external
+@pytest.mark.skip(reason="Requires OpenAI API key")
+def test_openai_metadata_extraction():
+    """Test actual OpenAI integration."""
+    pass
+
+# Use fixtures for common setup
+def test_document_processing(sample_pdf_path, db_session):
+    """Test uses fixtures from conftest.py"""
+    pass
+```
+
+---
+
+## 📝 Common Tasks
+
+### Adding a New API Endpoint
+
+1. Create endpoint in `app/api/`:
+```python
+# app/api/my_feature.py
+from fastapi import APIRouter, HTTPException
+from app.database import get_db
+from app.models import MyModel
+
+router = APIRouter(prefix="/api/my-feature", tags=["my-feature"])
+
+@router.get("/")
+async def list_items(db=Depends(get_db)):
+    """List all items."""
+    items = db.query(MyModel).all()
+    return items
+```
+
+2. Register router in `app/api/__init__.py`:
+```python
+from app.api import my_feature
+
+router.include_router(my_feature.router)
+```
+
+3. Add tests in `tests/test_api_my_feature.py`
+
+### Adding a New Celery Task
+
+1. Create task in `app/tasks/`:
+```python
+# app/tasks/my_task.py
+from app.celery_app import celery_app
+import logging
+
+logger = logging.getLogger(__name__)
+
+@celery_app.task(bind=True, max_retries=3)
+def my_background_task(self, param: str):
+    """
+    Description of what this task does.
+    
+    Args:
+        param: Description of parameter
+    """
+    try:
+        logger.info(f"Processing task with param: {param}")
+        # Task logic here
+        return {"status": "success"}
+    except Exception as e:
+        logger.error(f"Task failed: {e}")
+        raise self.retry(exc=e, countdown=60)
+```
+
+2. Import in `app/tasks/__init__.py`
+3. Add tests in `tests/test_tasks.py`
+
+### Adding a Database Model
+
+1. Define model in `app/models.py`:
+```python
+class MyModel(Base):
+    __tablename__ = "my_table"
+    
+    id = Column(Integer, primary_key=True, index=True)
+    name = Column(String, nullable=False)
+    created_at = Column(DateTime, default=datetime.utcnow)
+```
+
+2. Create migration:
+```bash
+cd /path/to/DocuElevate
+alembic revision --autogenerate -m "Add MyModel table"
+alembic upgrade head
+```
+
+3. Add model to tests fixtures
+
+### Adding a Storage Provider
+
+1. Create provider module in `app/tasks/storage/`:
+```python
+# app/tasks/storage/my_provider.py
+from app.config import settings
+import logging
+
+logger = logging.getLogger(__name__)
+
+def upload_to_my_provider(file_path: str, metadata: dict) -> str:
+    """
+    Upload file to My Provider.
+    
+    Args:
+        file_path: Local path to file
+        metadata: Document metadata
+        
+    Returns:
+        URL or ID of uploaded file
+        
+    Raises:
+        ProviderError: If upload fails
+    """
+    if not settings.my_provider_api_key:
+        raise ValueError("MY_PROVIDER_API_KEY not configured")
+    
+    # Implementation
+    pass
+```
+
+2. Add configuration to `app/config.py`:
+```python
+class Settings(BaseSettings):
+    # ... existing settings ...
+    my_provider_api_key: Optional[str] = None
+    my_provider_endpoint: Optional[str] = None
+```
+
+3. Add to `.env.demo`:
+```bash
+# My Provider
+MY_PROVIDER_API_KEY=your_api_key_here
+MY_PROVIDER_ENDPOINT=https://api.myprovider.com
+```
+
+4. Add validator in `app/utils/config_validator/`
+5. Add tests with mocked API calls
+
+---
+
+## 🔒 Security Best Practices
+
+### What to NEVER Do
+- ❌ Hardcode API keys, passwords, or secrets
+- ❌ Log sensitive data (passwords, tokens, API keys)
+- ❌ Accept unsanitized user input for file paths
+- ❌ Disable security features without documentation
+- ❌ Commit `.env` files or credentials
+
+### What to ALWAYS Do
+- ✅ Use `settings` from `app/config.py` for all configuration
+- ✅ Validate and sanitize all user inputs
+- ✅ Use parameterized database queries (SQLAlchemy handles this)
+- ✅ Check file paths for directory traversal (`Path.resolve()`)
+- ✅ Use appropriate HTTP status codes (401, 403, 404, etc.)
+- ✅ Log security-relevant events
+- ✅ Add rate limiting for sensitive endpoints
+- ✅ Use HTTPS in production (documented in deployment guide)
+
+### Input Validation Example
+```python
+from pathlib import Path
+from fastapi import HTTPException, status
+
+def validate_file_path(file_path: str, base_dir: str = "/workdir") -> Path:
+    """Validate file path is within allowed directory."""
+    try:
+        path = Path(file_path).resolve()
+        base = Path(base_dir).resolve()
+        
+        # Ensure path is within base directory
+        if not path.is_relative_to(base):
+            raise ValueError("Path outside allowed directory")
+        
+        return path
+    except Exception as e:
+        raise HTTPException(
+            status_code=status.HTTP_400_BAD_REQUEST,
+            detail=f"Invalid file path: {e}"
+        )
+```
+
+---
+
+## 🧪 Testing Strategy
+
+### Test Coverage Goals
+- **Target:** 80% overall coverage
+- **Critical modules:** 90%+ (auth, config, database)
+- **Tasks:** 70%+ (complex to test with external services)
+- **API endpoints:** 85%+
+
+### Test Types
+```python
+# Unit tests - fast, isolated, no external dependencies
+@pytest.mark.unit
+def test_hash_file_empty(tmp_path):
+    """Test hashing an empty file."""
+    file = tmp_path / "empty.txt"
+    file.write_text("")
+    assert hash_file(str(file)) == "expected_hash"
+
+# Integration tests - test multiple components together
+@pytest.mark.integration
+def test_upload_and_process(client, sample_pdf):
+    """Test full upload and processing flow."""
+    response = client.post("/api/upload", files={"file": sample_pdf})
+    assert response.status_code == 200
+
+# External service tests - skipped by default
+@pytest.mark.requires_external
+@pytest.mark.skipif(not os.getenv("OPENAI_API_KEY"), reason="No API key")
+def test_real_openai_extraction():
+    """Test actual OpenAI API (skipped in CI)."""
+    pass
+```
+
+### Running Tests
+```bash
+# All tests
+pytest
+
+# Specific category
+pytest -m unit
+pytest -m integration
+
+# With coverage
+pytest --cov=app --cov-report=html
+
+# Specific file
+pytest tests/test_api.py -v
+
+# Skip external services
+pytest -m "not requires_external"
+```
+
+---
+
+## 🚀 Performance Considerations
+
+### Async/Await
+- FastAPI endpoints are async by default
+- Use `async def` for I/O-bound operations
+- Use regular `def` for CPU-bound operations
+
+```python
+# Good - async for I/O
+@router.get("/files")
+async def list_files(db: Session = Depends(get_db)):
+    files = db.query(FileRecord).all()
+    return files
+
+# Also good - sync for CPU-heavy
+@router.post("/hash")
+def hash_large_file(file: UploadFile):
+    return compute_hash(file.file.read())
+```
+
+### Database Queries
+```python
+# Good - single query with join
+files = db.query(FileRecord).options(
+    joinedload(FileRecord.metadata)
+).filter(FileRecord.user_id == user_id).all()
+
+# Bad - N+1 queries
+files = db.query(FileRecord).filter(FileRecord.user_id == user_id).all()
+for file in files:
+    metadata = file.metadata  # Triggers separate query each time
+```
+
+### Celery Tasks
+```python
+# Long-running tasks should update progress
+@celery_app.task(bind=True)
+def process_large_batch(self, file_ids: List[int]):
+    total = len(file_ids)
+    for i, file_id in enumerate(file_ids):
+        process_file(file_id)
+        self.update_state(
+            state='PROGRESS',
+            meta={'current': i + 1, 'total': total}
+        )
+```
+
+---
+
+## 📚 Documentation Requirements
+
+### Code Documentation
+```python
+def complex_function(param1: str, param2: int = 10) -> Dict[str, Any]:
+    """
+    One-line summary of what the function does.
+    
+    More detailed explanation if needed. Can span multiple
+    lines and include examples.
+    
+    Args:
+        param1: Description of param1
+        param2: Description of param2, defaults to 10
+        
+    Returns:
+        Dictionary containing:
+            - key1: Description
+            - key2: Description
+            
+    Raises:
+        ValueError: If param1 is empty
+        FileNotFoundError: If file doesn't exist
+        
+    Examples:
+        >>> result = complex_function("test", 5)
+        >>> print(result['key1'])
+        'value'
+    """
+    pass
+```
+
+### API Documentation
+- Use FastAPI's automatic OpenAPI generation
+- Add descriptions to endpoints
+- Document request/response models
+- Include example requests/responses
+
+```python
+@router.post(
+    "/upload",
+    response_model=UploadResponse,
+    status_code=status.HTTP_201_CREATED,
+    summary="Upload a document",
+    description="Upload a document for processing. Supports PDF, images, and Office documents.",
+    responses={
+        201: {"description": "Document uploaded successfully"},
+        400: {"description": "Invalid file format"},
+        413: {"description": "File too large"},
+    }
+)
+async def upload_document(
+    file: UploadFile = File(..., description="Document file to upload"),
+    tags: List[str] = Query([], description="Optional tags for the document"),
+):
+    """Upload endpoint implementation."""
+    pass
+```
+
+---
+
+## 🐛 Debugging
+
+### Logging
+```python
+import logging
+
+logger = logging.getLogger(__name__)
+
+# Use appropriate log levels
+logger.debug("Detailed information for debugging")
+logger.info("General information about operation")
+logger.warning("Warning about potential issue")
+logger.error("Error that needs attention")
+logger.critical("Critical error that needs immediate attention")
+
+# Include context in logs
+logger.info(f"Processing document: {file_id}, user: {user_id}")
+
+# Don't log sensitive data
+logger.info(f"User authenticated")  # Good
+logger.info(f"Password: {password}")  # BAD!
+```
+
+### Common Issues
+
+1. **Import Errors**
+   - Check if module is in `__init__.py`
+   - Verify Python path includes project root
+   - Look for circular imports
+
+2. **Database Issues**
+   - Check if migrations are up to date: `alembic upgrade head`
+   - Verify DATABASE_URL is set correctly
+   - Check if tables exist: `sqlite3 app/database.db .schema`
+
+3. **Celery Issues**
+   - Verify Redis is running: `redis-cli ping`
+   - Check Celery worker logs
+   - Ensure tasks are imported in `celery_worker.py`
+
+4. **Test Failures**
+   - Check if test database is clean (use fixtures)
+   - Verify environment variables are set in `conftest.py`
+   - Run single test to isolate issue: `pytest tests/test_file.py::test_name -v`

+nationality, personal appearance, race, caste, color, religion, or sexual
+identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall
+  community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or advances of
+  any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email address,
+  without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official email address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+code-of-conduct@fret.de.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of
+actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or permanent
+ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the
+community.

+
+### Document Ingestion
+Documents enter DocuElevate through three possible channels:
+1. **Web Upload**: Users manually upload files via the web interface
+2. **Email Attachments**: Automatic polling of configured IMAP mailboxes (supports multiple accounts)
+3. **API**: Direct programmatic uploads via the REST API
+
+### Processing Pipeline
+Every document goes through the following steps:
+1. **PDF Conversion**: Non-PDF files are converted to PDF format using Gotenberg
+2. **OCR Processing**: Azure Document Intelligence extracts text from images/scans
+3. **Metadata Extraction**: OpenAI analyzes document content to identify:
+   - Document type (invoice, receipt, contract, etc.)
+   - Key entities (dates, names, amounts, account numbers)
+   - Important data points specific to the document type
+4. **Enrichment**: Metadata is attached to the document in a structured format
+
+### Distribution
+Processed documents with their metadata can be automatically sent to:
+- **Dropbox**: For cloud storage and sharing
+- **Nextcloud**: For self-hosted file storage
+- **Google Drive**: For Google Workspace integration
+- **Paperless-NGX**: For advanced document management with search capabilities
+
+Users can choose to send documents to any combination of these destinations through configuration settings or manual selection.

-## Running as a Docker Container
-
-This project uses Celery (with Redis) for asynchronous task management and Gotenberg for PDF conversion. The `docker-compose.yml` file defines these services:
-
-- **API Service**: Runs the FastAPI application via `uvicorn`.
-- **Worker Service**: Runs the Celery worker for processing tasks (PDF conversions, OCR, etc.).
-- **Redis**: Provides the message broker & result backend for Celery.
-- **Gotenberg**: Offers PDF conversion capabilities.
-
-### Running the Application with Docker Compose
-
-1. **Install Docker and Docker Compose** on your system.  
-2. **Clone the repository** and navigate into it:
-   ```bash
-   git clone <repository_url>
-   cd <repository_name>
-   ```
-3. **Create and configure the `.env` file**:
-   - Fill in the variables from the tables above.  
-   - (At minimum, you need `DATABASE_URL`, `REDIS_URL`, `WORKDIR`, plus whichever service creds you plan to use.)
-4. **Launch the services**:
-   ```bash
-   docker-compose up -d
-   ```
-5. The API will be available at **`http://localhost:8000`**, and the API documentation is available at **`http://localhost:8000/docs`**.

+# Security Audit Report
+
+**Date:** 2026-02-06  
+**Status:** Completed Initial Assessment
+
+## Executive Summary
+
+This document tracks security vulnerabilities found in DocuElevate and their remediation status.
+
+## Critical Vulnerabilities (Fixed) ✅
+
+### 1. Outdated Authlib with Known Vulnerabilities
+**Status:** ✅ FIXED  
+**Severity:** HIGH  
+**Description:** Authlib version 1.3.2 had two critical vulnerabilities:
+- CVE: Denial of Service via Oversized JOSE Segments
+- CVE: JWS/JWT accepts unknown crit headers (RFC violation → possible authz bypass)
+
+**Fix:** Updated `requirements.txt` to require `authlib>=1.6.5`
+
+### 2. Starlette DoS Vulnerability
+**Status:** ✅ FIXED  
+**Severity:** MEDIUM  
+**Description:** Starlette 0.41.3 vulnerable to O(n^2) DoS via Range header merging in `FileResponse`
+
+**Fix:** Updated `requirements.txt` to require `starlette>=0.49.1`
+
+### 3. Weak SESSION_SECRET Default
+**Status:** ✅ FIXED  
+**Severity:** HIGH  
+**Description:** Default SESSION_SECRET value in `app/main.py` was a predictable string that could be exploited if not overridden
+
+**Fix:** 
+- Enhanced validation in `app/main.py` to raise error if auth is enabled without proper secret
+- Updated default to be clearly marked as insecure for development only
+- Added generation instructions in error message
+
+## Medium Risk Issues (Fixed) ✅
+
+### 4. Insufficient .gitignore Protection
+**Status:** ✅ FIXED  
+**Severity:** MEDIUM  
+**Description:** .gitignore didn't adequately protect against accidentally committing sensitive files (credentials, private keys, secrets)
+
+**Fix:** Enhanced `.gitignore` with comprehensive patterns for:
+- Various environment file formats
+- Credential JSON files
+- Private keys (.pem, .key, .pfx, etc.)
+- SSH keys
+- Explicit exclusion of patterns where needed
+
+## Best Practices Implemented
+
+### Dependency Management
+- ✅ Version pinning for security-critical packages (authlib, starlette)
+- ✅ Advisory database checks integrated into development workflow
+- ⏳ TODO: Add automated dependency vulnerability scanning in CI/CD
+
+### Authentication & Secrets
+- ✅ Strong validation for SESSION_SECRET (minimum 32 characters)
+- ✅ Error-on-missing for critical security settings when auth enabled
+- ✅ Clear documentation of secret generation methods
+- ✅ .env.demo file for configuration examples (no real secrets)
+
+### Configuration Security
+- ✅ All secrets loaded from environment variables
+- ✅ No hardcoded credentials in codebase
+- ✅ Proper masking in configuration validators
+
+## Ongoing Security Measures
+
+### CI/CD Security
+- ⏳ **TODO:** Add CodeQL scanning to GitHub Actions
+- ⏳ **TODO:** Add Bandit (Python security linter) to CI pipeline
+- ⏳ **TODO:** Add dependency vulnerability scanning (Safety, pip-audit)
+- ⏳ **TODO:** Make security scans blocking (fail on critical issues)
+
+### Code Security
+- ⏳ **TODO:** Implement rate limiting on API endpoints
+- ⏳ **TODO:** Add CSRF protection for state-changing operations
+- ⏳ **TODO:** Implement request size limits
+- ⏳ **TODO:** Add input sanitization for all user inputs
+- ⏳ **TODO:** Implement proper API key rotation mechanisms
+
+### Infrastructure Security
+- ✅ TrustedHostMiddleware configured
+- ✅ ProxyHeadersMiddleware for reverse proxy setup
+- ⏳ **TODO:** Add security headers (HSTS, CSP, X-Frame-Options)
+- ⏳ **TODO:** Implement proper CORS configuration
+- ⏳ **TODO:** Add request logging with sensitive data masking
+
+## Recommendations
+
+### High Priority
+1. **Enable CodeQL scanning** - Automated security vulnerability detection
+2. **Implement rate limiting** - Prevent abuse and DoS attacks
+3. **Add comprehensive input validation** - Prevent injection attacks
+4. **Implement API authentication** - Secure all API endpoints properly
+
+### Medium Priority
+1. **Add security headers** - Improve browser-side security
+2. **Implement audit logging** - Track security-relevant events
+3. **Add automated security testing** - Integration with CI/CD
+4. **Document security architecture** - Security design decisions
+
+### Low Priority
+1. **Security training documentation** - For contributors
+2. **Penetration testing** - Professional security assessment
+3. **Bug bounty program** - Community security contributions

+
+## Required Configuration Parameters
+
+| **Variable**                    | **Description**                                       |
+|---------------------------------|-------------------------------------------------------|
+| `AWS_ACCESS_KEY_ID`             | AWS IAM access key ID                                 |
+| `AWS_SECRET_ACCESS_KEY`         | AWS IAM secret access key                             |
+| `AWS_REGION`                    | AWS region where your S3 bucket is located (default: `us-east-1`) |
+| `S3_BUCKET_NAME`                | Name of your S3 bucket                                |
+| `S3_FOLDER_PREFIX`              | Optional prefix/folder path for uploaded files        |
+| `S3_STORAGE_CLASS`              | Storage class for uploaded objects (default: `STANDARD`) |
+| `S3_ACL`                        | Access control for uploaded files (default: `private`) |
+
+For a complete list of configuration options, see the [Configuration Guide](ConfigurationGuide.md).
+
+## Step-by-Step Setup Instructions
+
+### 1. Create an S3 bucket
+
+1. Go to the [Amazon S3 Console](https://s3.console.aws.amazon.com/)
+2. Click "Create bucket"
+3. Enter a globally unique name for your bucket
+4. Select your preferred AWS region
+5. Configure other settings as needed (block public access is recommended)
+6. Click "Create bucket"
+
+### 2. Create an IAM User with S3 Access
+
+1. Go to the [AWS IAM Console](https://console.aws.amazon.com/iam/)
+2. Navigate to "Users" and click "Add users"
+3. Enter a name (e.g., "docuelevate-s3-access")
+4. For access type, select "Programmatic access"
+5. Click "Next: Permissions"
+6. Choose "Attach existing policies directly" and search for "AmazonS3FullAccess"
+7. For more security, you can create a custom policy limiting access to just your bucket
+8. Click through to review and create the user
+9. On the final page, you'll see the Access Key ID and Secret Access Key
+10. Save these credentials securely as they won't be shown again
+
+### 3. Configure DocuElevate
+
+1. Set `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` to the credentials from step 2
+2. Set `AWS_REGION` to the region where your bucket was created (e.g., "us-east-1")
+3. Set `S3_BUCKET_NAME` to your bucket name
+4. Set `S3_FOLDER_PREFIX` to organize files in specific subfolder paths (e.g., "invoices/" or "documents/2023/")
+5. Optionally customize `S3_STORAGE_CLASS` and `S3_ACL` for your storage needs
+
+### 4. Optional: Create a Custom IAM Policy (for better security)
+
+1. In IAM console, go to "Policies" and click "Create policy"
+2. Use the JSON editor and paste a policy like this (replace `your-bucket-name`):
+   ```json
+   {
+       "Version": "2012-10-17",
+       "Statement": [
+           {
+               "Effect": "Allow",
+               "Action": [
+                   "s3:PutObject",
+                   "s3:GetObject",
+                   "s3:ListBucket"
+               ],
+               "Resource": [
+                   "arn:aws:s3:::your-bucket-name",
+                   "arn:aws:s3:::your-bucket-name/*"
+               ]
+           }
+       ]
+   }
+   ```
+3. After creating the policy, attach it to your user instead of the broader AmazonS3FullAccess
+
+## Storage Class Options
+
+Amazon S3 offers several storage classes to optimize costs:
+
+| **Storage Class** | **Use Case** | **Retrieval Time** |
+|------------------|--------------|-------------------|
+| `STANDARD` | Default, frequently accessed data | Immediate |
+| `INTELLIGENT_TIERING` | Data with changing or unknown access patterns | Immediate |
+| `STANDARD_IA` | Long-lived, infrequently accessed data | Immediate |
+| `ONEZONE_IA` | Long-lived, infrequently accessed, non-critical data | Immediate |
+| `GLACIER_IR` | Archive data that needs immediate access | Immediate |
+| `GLACIER` | Archive data that rarely needs to be accessed | Minutes to hours |
+| `DEEP_ARCHIVE` | Long-term archive and digital preservation | Hours |
+
+Set your preferred storage class using the `S3_STORAGE_CLASS` parameter.
+
+## Access Control List (ACL) Options
+
+Common ACL values include:
+
+- `private` (default) - Only the bucket owner has access
+- `public-read` - Anyone can read the file (use cautiously)
+- `bucket-owner-full-control` - Useful for cross-account uploads
+
+For most document storage scenarios, `private` is recommended for security.

+
+## Authentication Methods
+
+DocuElevate supports two primary authentication methods:
+
+1. **Simple Authentication** - Basic username/password authentication managed by DocuElevate
+2. **OpenID Connect** - Integration with identity providers like Authentik, Keycloak, or Auth0
+
+## Session Security
+
+DocuElevate uses FastAPI's session management to maintain user sessions. The session data is stored in cookies that are encrypted and signed using your application's secret key. This prevents tampering with session data while ensuring users remain authenticated between requests.
+
+The `SESSION_SECRET` is automatically used by the web framework to:
+
+1. Encrypt and sign session cookies
+2. Protect against cross-site request forgery (CSRF) attacks
+3. Secure other session-related functionality
+
+Always use a strong, randomly generated secret key of at least 32 characters for production environments.
+
+### Generating a Secure Session Secret
+
+You can generate a secure random string using Python:
+
+```python
+import secrets
+print(secrets.token_hex(32))  # Outputs a 64-character hex string (32 bytes)
+```
+
+Or using OpenSSL:
+
+```bash
+openssl rand -hex 32
+```
+
+Make sure to keep this secret value confidential and don't reuse it across different applications.
+
+## Setting up Simple Authentication
+
+For smaller deployments or testing, simple authentication is easy to set up:
+
+1. In your `.env` file, set:
+   ```
+   AUTH_ENABLED=True
+   SESSION_SECRET=your-secure-random-string-at-least-32-chars
+   ADMIN_USERNAME=your_admin_username
+   ADMIN_PASSWORD=your_secure_password
+   ```
+
+2. Restart DocuElevate to apply the changes
+
+3. When you navigate to the application, you'll be prompted to log in with the credentials you set
+
+
+## Setting up OpenID Connect with Authentik
+
+For larger deployments or when you need more advanced authentication features, OpenID Connect (OIDC) is recommended:
+
+### 1. Create an Application in Authentik
+
+1. Log in to your Authentik admin interface
+2. Navigate to "Applications" > "Applications" 
+3. Click "Create"
+4. Fill in the following details:
+   - **Name**: DocuElevate
+   - **Slug**: docuelevate
+   - **Provider**: Create a new OAuth2/OIDC Provider
+   - **Launch URL**: The URL of your DocuElevate instance (e.g., https://docuelevate.example.com)
+
+5. For the OAuth2/OIDC Provider settings:
+   - **Client Type**: Confidential
+   - **Redirect URIs**: https://docuelevate.example.com/auth (adjust for your domain)
+   - **Signing Key**: Select an appropriate signing key
+   - **Scopes**: Select "openid", "email", and "profile" at minimum
+
+6. Save the provider and then the application
+
+7. Note down the **Client ID** and **Client Secret** from the provider details
+
+### 2. Configure DocuElevate
+
+1. In your `.env` file, set:
+   ```
+   AUTH_ENABLED=True
+   SESSION_SECRET=your-secure-random-string-at-least-32-chars
+   AUTHENTIK_CLIENT_ID=your_client_id_from_authentik
+   AUTHENTIK_CLIENT_SECRET=your_client_secret_from_authentik
+   AUTHENTIK_CONFIG_URL=https://auth.example.com/application/o/docuelevate/.well-known/openid-configuration
+   OAUTH_PROVIDER_NAME=Authentik SSO
+   ```
+
+2. Adjust the `AUTHENTIK_CONFIG_URL` to match your Authentik instance and application slug
+
+3. Restart DocuElevate to apply the changes
+
+### 3. Test the Authentication
+
+1. Navigate to your DocuElevate instance
+2. You should be redirected to the Authentik login page
+3. After successful authentication, you'll be redirected back to DocuElevate
+
+## Using Other OpenID Connect Providers
+
+DocuElevate can work with any OpenID Connect-compliant provider, not just Authentik:
+
+### Keycloak Setup
+
+1. Create a client in Keycloak with:
+   - **Client ID**: your preferred client ID
+   - **Access Type**: confidential
+   - **Valid Redirect URIs**: https://docuelevate.example.com/auth
+
+2. Get the client secret from the "Credentials" tab
+
+3. Configure DocuElevate with:
+   ```
+   AUTHENTIK_CLIENT_ID=your_keycloak_client_id
+   AUTHENTIK_CLIENT_SECRET=your_keycloak_client_secret
+   AUTHENTIK_CONFIG_URL=https://keycloak.example.com/auth/realms/your-realm/.well-known/openid-configuration
+   OAUTH_PROVIDER_NAME=Keycloak SSO
+   ```
+
+### Auth0 Setup
+
+1. Create a new application in Auth0
+2. Get your client ID and secret
+3. Set the callback URL to https://docuelevate.example.com/auth
+4. Configure DocuElevate with:
+   ```
+   AUTHENTIK_CLIENT_ID=your_auth0_client_id
+   AUTHENTIK_CLIENT_SECRET=your_auth0_client_secret
+   AUTHENTIK_CONFIG_URL=https://your-tenant.auth0.com/.well-known/openid-configuration
+   OAUTH_PROVIDER_NAME=Auth0
+   ```
+
+## Security Considerations
+
+1. **Always use HTTPS** in production to protect authentication tokens and passwords
+2. Generate a strong, random `SESSION_SECRET` (at least 32 characters)
+3. Use strong passwords for simple authentication
+4. Consider using a password manager to generate and store your admin credentials
+5. Restrict the scopes requested from your OIDC provider to only what's needed
+6. Consider setting up user groups and permissions in your identity provider
+7. If using simple authentication in production, consider implementing rate limiting for login attempts
+
+## Troubleshooting Authentication Issues
+
+If you encounter issues with authentication:
+
+1. **Login failures with simple authentication**:
+   - Verify that the username and password exactly match the values in your `.env` file
+   - Check if there are leading or trailing spaces in your credentials
+   - Ensure your `.env` file is properly loaded by the application
+
+2. **Session issues**:
+   - Check that your `SESSION_SECRET` is set correctly
+   - Clear browser cookies and cache if experiencing persistent login issues
+
+3. **OIDC issues**:
+   - **Redirect URI mismatch**: Ensure the redirect URI in your provider configuration exactly matches your DocuElevate URL + "/auth"
+   - **SSL-related errors**: Make sure your certificates are valid and trusted
+   - **Provider connectivity**: Ensure DocuElevate can reach your identity provider
+
+4. **Token validation errors**:
+   - Check that the clocks are synchronized between DocuElevate and the identity provider
+   - Verify that the signing keys are correctly configured
+
+5. **Debug OpenID information**:
+   - For most providers, you can visit the `/.well-known/openid-configuration` endpoint to verify their settings
+
+For more general configuration issues, see the [Configuration Troubleshooting Guide](ConfigurationTroubleshooting.md).
