+# Build Metadata Automation
+
+## Overview
+
+DocuElevate automatically generates and embeds build metadata (version, build date, Git commit SHA) into the application at build time. This metadata is displayed in the `/status` endpoint and helps track which version of the application is running in production.
+
+## What is Automated
+
+The following metadata is automatically generated and included in every build:
+
+1. **Build Date** - The UTC date when the build was created (format: YYYY-MM-DD)
+2. **Git Commit SHA** - The short Git commit hash (7 characters) of the code being built
+3. **Runtime Information** - A comprehensive summary including version, dates, commit info, and more
+4. **Application Version** - Read from the `VERSION` file (manually updated for releases)
+
+## How It Works
+
+### Build Time Generation
+
+When the Docker image is built (locally or in CI/CD), the following happens:
+
+1. **GitHub Actions runs the metadata script** (`scripts/generate_build_metadata.sh`) before building the Docker image
+2. **The script generates three files:**
+   - `BUILD_DATE` - Contains the build date in YYYY-MM-DD format
+   - `GIT_SHA` - Contains the short Git commit hash
+   - `RUNTIME_INFO` - Contains detailed build information
+3. **Docker copies these files** into the image during the build process
+4. **The application reads the files** at runtime via `app/config.py` properties
+
+### File Structure
+
+```
+DocuElevate/
+├── scripts/
+│   └── generate_build_metadata.sh    # Script that generates metadata
+├── VERSION                             # Manually maintained version number
+├── BUILD_DATE                          # Generated at build time (gitignored)
+├── GIT_SHA                            # Generated at build time (gitignored)
+└── RUNTIME_INFO                        # Generated at build time (gitignored)
+```
+
+### Generated Files Format

+**BUILD_DATE:**
+```

+
+**GIT_SHA:**

+
+## Configuration Properties
+
+The `app/config.py` Settings class provides these properties for accessing build metadata:
+
+### `settings.version` (property)
+Returns the application version with the following priority:
+1. `APP_VERSION` environment variable
+2. Contents of `VERSION` file
+3. Default: `"0.3.2-dev"`
+
+### `settings.build_date` (property)
+Returns the build date with the following priority:
+1. `BUILD_DATE` environment variable
+2. Contents of `BUILD_DATE` file
+3. Default: `"Unknown build date"`
+
+### `settings.git_sha` (property)
+Returns the Git commit SHA with the following priority:
+1. `GIT_COMMIT_SHA` environment variable
+2. Contents of `GIT_SHA` file
+3. Default: `"unknown"`
+
+### `settings.runtime_info` (property)
+Returns detailed runtime information:
+1. Contents of `RUNTIME_INFO` file
+2. Default: Basic info string with version, build date, and Git SHA
+
+## Usage in Application
+
+### In Python Code
+
+```python
+from app.config import settings
+
+# Get version
+version = settings.version  # "0.4.5-dev"
+
+# Get build date
+build_date = settings.build_date  # "2026-02-07"
+
+# Get Git SHA
+git_sha = settings.git_sha  # "6812d0d"
+
+# Get full runtime info
+runtime_info = settings.runtime_info  # Full multi-line string
+```
+
+### In Templates
+
+The `/status` endpoint uses these properties to display metadata:
+
+```python
+# app/views/status.py
+return templates.TemplateResponse(
+    "status_dashboard.html",
+    {
+        "app_version": settings.version,
+        "build_date": settings.build_date,
+        "container_info": {
+            "git_sha": settings.git_sha[:7],
+            "runtime_info": settings.runtime_info,
+        }
+    }
+)
+```
+
+## GitHub Actions Integration
+
+The build metadata is generated in two GitHub Actions workflows:
+
+### docker-build.yaml
+```yaml
+- name: Generate Build Metadata
+  run: |
+    chmod +x scripts/generate_build_metadata.sh
+    ./scripts/generate_build_metadata.sh
+```
+
+### docker-ci.yml
+```yaml
+- name: Generate Build Metadata
+  run: |
+    chmod +x scripts/generate_build_metadata.sh
+    ./scripts/generate_build_metadata.sh
+```
+
+These steps run **before** the Docker build step, ensuring the metadata files exist when Docker copies them into the image.
+
+## Local Development
+
+### Manual Generation
+
+To generate build metadata locally:
+
+```bash
+# Run the script
+./scripts/generate_build_metadata.sh
+
+# Output:
+# Generating build metadata...
+# ✓ BUILD_DATE: 2026-02-07
+# ✓ GIT_SHA: 6812d0d
+# ✓ VERSION: 0.4.5-dev
+# ✓ RUNTIME_INFO generated
+```
+
+### Local Docker Build
+
+When building Docker images locally:
+
+```bash
+# Generate metadata first
+./scripts/generate_build_metadata.sh
+
+# Then build the Docker image
+docker build -t docuelevate:local .
+
+# Or use docker-compose
+docker-compose build
+```
+
+### Testing Without Docker
+
+The application will still work without the generated files:
+
+- `BUILD_DATE` will show "Unknown build date"
+- `GIT_SHA` will show "unknown"
+- The app will use defaults from `app/config.py`
+
+## Environment Variable Override
+
+You can override any metadata value using environment variables:
+
+```bash
+# Override version
+export APP_VERSION="1.0.0-custom"
+
+# Override build date
+export BUILD_DATE="2026-01-15"
+
+# Override Git SHA
+export GIT_COMMIT_SHA="abc1234"
+
+# Run the application
+python -m uvicorn app.main:app
+```
+
+This is useful for:
+- Custom builds
+- Testing different versions
+- Development environments
+
+## Updating the Version
+
+The `VERSION` file must be **manually updated** for releases:
+
+```bash
+# Update version for a new release
+echo "0.5.0" > VERSION
+
+# Commit the change
+git add VERSION
+git commit -m "Bump version to 0.5.0"
+git tag v0.5.0
+git push origin main --tags
+```
+
+The build metadata script will automatically include this version in all builds.
+
+## Troubleshooting
+
+### Problem: Build metadata shows "unknown"
+
+**Solution:** Ensure the script runs before Docker build:
+```bash
+./scripts/generate_build_metadata.sh
+docker build -t docuelevate .
+```
+
+### Problem: Git SHA is "unknown"
+
+**Cause:** Building outside of a Git repository
+
+**Solution:** 
+- Clone the repository properly with `.git` directory
+- Or set `GIT_COMMIT_SHA` environment variable
+
+### Problem: Build date is outdated
+
+**Cause:** Using cached Docker layers
+
+**Solution:**
+```bash
+# Rebuild without cache
+docker build --no-cache -t docuelevate .
+```
+
+### Problem: Files not copied to Docker image
+
+**Cause:** Files listed in `.dockerignore`
+
+**Solution:** 
+- Check `.dockerignore` doesn't block `BUILD_DATE`, `GIT_SHA`, or `RUNTIME_INFO`
+- The `VERSION` file should always be committed to git
+
+## Best Practices
+
+1. **Always run the script before building** - The CI/CD pipeline does this automatically
+2. **Don't commit generated files** - `GIT_SHA` and `RUNTIME_INFO` are in `.gitignore`
+3. **Update VERSION manually** - Only update for actual releases
+4. **Use semantic versioning** - Follow `MAJOR.MINOR.PATCH` format
+5. **Tag releases in Git** - Create Git tags for version releases
+

+## Future Enhancements
+
+Potential improvements to the build metadata system:
+
+1. **Automated version bumping** - Automatically increment version based on commits
+2. **Changelog generation** - Auto-generate changelog from Git history
+3. **Build number tracking** - Track sequential build numbers
+4. **Deployment tracking** - Record when/where each build was deployed
+5. **Performance metrics** - Include build time, image size, etc.
