+# USDA Vision - Nix Flake Setup
+
+This directory now has a Nix flake for building and developing the USDA Vision system, with ragenix for managing secrets.
+
+## Quick Start
+
+### Development Environment
+
+Enter the development shell with all tools:
+
+```bash
+cd usda-vision
+nix develop
+```
+
+This gives you:
+- Docker & Docker Compose
+- Node.js 20 with npm/pnpm
+- Python 3.11 with pip/virtualenv
+- Supabase CLI
+- Camera SDK (automatically in `LD_LIBRARY_PATH`)
+- ragenix for secrets management
+- All standard utilities (jq, yq, rsync, etc.)
+
+### Building
+
+Build the package:
+
+```bash
+nix build
+# Or explicitly:
+nix build .#usda-vision
+```
+
+Build just the camera SDK:
+
+```bash
+nix build .#camera-sdk
+```
+
+## Secrets Management with ragenix
+
+### Initial Setup
+
+1. **Generate or use an age key**:
+
+```bash
+# Option 1: Generate a new age key
+mkdir -p ~/.config/age
+age-keygen -o ~/.config/age/keys.txt
+
+# Option 2: Use your SSH key
+ssh-to-age < ~/.ssh/id_ed25519.pub
+# Copy the output to secrets/secrets.nix
+```
+
+2. **Add your public key** to [secrets/secrets.nix](secrets/secrets.nix):
+
+```nix
+{
+  publicKeys = [
+    "age1your_public_key_here"
+    # or
+    "ssh-ed25519 AAAA... user@host"
+  ];
+}
+```
+
+3. **Create encrypted environment files**:
+
+```bash
+nix develop  # Enter dev shell first
+ragenix -e secrets/env.age
+```
+
+This opens your `$EDITOR` to edit the encrypted file. Add your environment variables:
+
+```bash
+# Web environment (Vite)
+VITE_SUPABASE_URL=http://exp-dash:54321
+VITE_SUPABASE_ANON_KEY=your-anon-key-here
+# ... etc
+```
+
+For Azure OAuth:
+
+```bash
+ragenix -e secrets/env.azure.age
+```
+
+### Using Secrets in Development
+
+In the development shell, you can:
+
+```bash
+# Edit secrets
+ragenix -e secrets/env.age
+
+# View decrypted content (careful in shared screens!)
+age -d -i ~/.config/age/keys.txt secrets/env.age
+
+# Re-encrypt all secrets after adding a new public key
+ragenix -r
+```
+
+### Using Secrets in Production (NixOS)
+
+The flake includes a NixOS module that handles secrets automatically:
+
+```nix
+# In your NixOS configuration
+{
+  inputs.usda-vision.url = "path:/path/to/usda-vision";
+  
+  # ... in your module:
+  imports = [ inputs.usda-vision.nixosModules.default ];
+  
+  services.usda-vision = {
+    enable = true;
+    secretsFile = config.age.secrets.usda-vision-env.path;
+  };
+  
+  # Configure ragenix/agenix to decrypt the secrets
+  age.secrets.usda-vision-env = {
+    file = inputs.usda-vision + "/secrets/env.age";
+    mode = "0644";
+    owner = "root";
+  };
+}
+```
+
+## Project Structure
+
+```
+usda-vision/
+├── flake.nix           # Flake definition with outputs
+├── package.nix         # Main application build
+├── camera-sdk.nix      # Camera SDK build

+│   ├── env.age         # Encrypted .env (safe to commit)
+│   ├── env.azure.age   # Encrypted Azure config (safe to commit)
+│   └── README.md       # Secrets documentation
+└── ... (rest of the app)
+```
+
+## Migration from Old Setup
+
+### Old Workflow
+- Manual `.env` file management
+- Secrets in plaintext (git-ignored)
+- Build defined in parent `default.nix`
+
+### New Workflow
+- Encrypted `.age` files in git
+- Secrets managed with ragenix
+- Self-contained flake in `usda-vision/`
+- Development shell with all tools
+
+### Migration Steps
+
+1. **Encrypt existing `.env` files**:
+
+```bash
+cd usda-vision
+nix develop
+
+# Setup your age key first (see above)
+
+# Encrypt the main .env
+ragenix -e secrets/env.age
+# Paste contents of old .env file, save and exit
+
+# Encrypt Azure config
+ragenix -e secrets/env.azure.age  
+# Paste contents of old .env.azure file, save and exit
+```
+
+2. **Delete unencrypted files** (they're git-ignored but still local):
+
+```bash
+rm .env .env.azure management-dashboard-web-app/.env
+```
+
+3. **Commit encrypted secrets**:
+
+```bash
+git add secrets/env.age secrets/env.azure.age secrets/secrets.nix
+git commit -m "Add encrypted secrets with ragenix"
+```
+
+## Benefits
+
+### Security
+- ✅ Secrets encrypted at rest
+- ✅ Safe to commit to git
+- ✅ Key-based access control
+- ✅ Audit trail (git history)
+
+### Development
+- ✅ Reproducible environment
+- ✅ All tools included
+- ✅ No manual setup
+- ✅ Version-locked dependencies
+
+### Deployment
+- ✅ Declarative secrets management
+- ✅ Automatic decryption on NixOS
+- ✅ No manual key distribution
+- ✅ Clean integration with existing infrastructure
+
+## Common Tasks
+
+### Add a new developer
+
+1. They generate an age key or use their SSH key
+2. They send you their public key
+3. You add it to `secrets/secrets.nix`
+4. Re-encrypt all secrets: `ragenix -r`
+5. Commit and push
+
+### Rotate a secret
+
+1. Edit the encrypted file: `ragenix -e secrets/env.age`
+2. Update the value
+3. Save and exit
+4. Commit: `git commit secrets/env.age -m "Rotate API key"`
+
+### Build without flakes
+
+If you need to build on a system without flakes enabled:
+
+```bash
+nix-build -E '(import (fetchTarball https://github.com/edolstra/flake-compat/archive/master.tar.gz) { src = ./.; }).defaultNix.default'
+```
+
+## Troubleshooting
+
+### "error: getting status of '...': No such file or directory"
+
+Make sure you're in the `usda-vision` directory when running `nix develop` or `nix build`.
+
+### "cannot decrypt: no valid identity"
+
+Your age private key isn't found. Check:
+- `~/.config/age/keys.txt` exists
+- Your public key is in `secrets/secrets.nix`
+- You've run `ragenix -r` after adding your key
+
+### "experimental feature 'flakes' not enabled"
+
+Add to `~/.config/nix/nix.conf`:
+```
+experimental-features = nix-command flakes
+```
+
+Or run with: `nix --experimental-features 'nix-command flakes' develop`

+
+## Next Steps
+
+### 1. Commit the Flake Files
+
+The flake needs to be in git to work:
+
+```bash
+cd /home/engr-ugaif/usda-dash-config/usda-vision
+
+# Add all new flake files
+git add flake.nix package.nix camera-sdk.nix secrets.nix
+git add secrets/secrets.nix secrets/README.md secrets/.gitignore
+git add FLAKE_SETUP.md setup-dev.sh .envrc .gitignore
+
+# Commit
+git commit -m "Add Nix flake with ragenix secrets management
+
+- Self-contained flake build system
+- Development shell with all tools
+- ragenix for encrypted secrets
+- Modular package definitions
+"
+```
+
+### 2. Set Up Your Age Key
+
+```bash
+cd /home/engr-ugaif/usda-dash-config/usda-vision
+
+# Option A: Use the interactive setup script
+./setup-dev.sh
+
+# Option B: Manual setup
+mkdir -p ~/.config/age
+age-keygen -o ~/.config/age/keys.txt
+# Then add your public key to secrets/secrets.nix
+```
+
+### 3. Encrypt Your Secrets
+
+```bash
+# Enter the development environment
+nix develop
+
+# Encrypt main .env file
+ragenix -e secrets/env.age
+# Paste your current .env contents, save, exit
+
+# Encrypt Azure config
+ragenix -e secrets/env.azure.age  
+# Paste your current .env.azure contents, save, exit
+
+# Commit encrypted secrets
+git add secrets/env.age secrets/env.azure.age
+git commit -m "Add encrypted environment configuration"
+```
+
+### 4. Test the Setup
+
+```bash
+# Test that the build works
+nix build
+
+# Test the development shell
+nix develop
+# You should see a welcome message
+
+# Inside the dev shell, verify tools
+docker-compose --version
+supabase --version
+ragenix --help
+```
+
+### 5. Update the Parent Repository
+
+```bash
+cd /home/engr-ugaif/usda-dash-config
+
+# Commit the updated default.nix
+git add default.nix NIX_FLAKE_MIGRATION.md
+git commit -m "Update default.nix to use usda-vision flake
+
+- Removed inline derivations
+- Now references usda-vision flake packages
+- Cleaner, more maintainable code
+"
+```
+
+### 6. Clean Up Old Files (Optional)
+
+After verifying everything works, you can delete the old plaintext secrets:
+
+```bash
+cd /home/engr-ugaif/usda-dash-config/usda-vision
+
+# These are already git-ignored, but remove them locally
+rm -f .env .env.azure management-dashboard-web-app/.env
+
+echo "✅ Old plaintext secrets removed"
+```
+
+## Verification Checklist
+
+- [ ] Flake files committed to git
+- [ ] Age key generated at `~/.config/age/keys.txt`
+- [ ] Public key added to `secrets/secrets.nix`
+- [ ] Secrets encrypted and committed
+- [ ] `nix build` succeeds
+- [ ] `nix develop` works
+- [ ] Parent `default.nix` updated and committed
+- [ ] Old `.env` files deleted
+
+## Usage Quick Reference
+
+### Development
+
+```bash
+# Enter dev environment (one-time per session)
+cd usda-vision
+nix develop
+
+# Edit secrets
+ragenix -e secrets/env.age
+
+# Normal docker-compose workflow
+docker-compose up -d
+docker-compose logs -f
+```
+
+### Building
+
+```bash
+# Build everything
+nix build
+
+# Build specific packages
+nix build .#usda-vision
+nix build .#camera-sdk
+```
+
+### Secrets Management
+
+```bash
+# Edit encrypted secret
+ragenix -e secrets/env.age
+
+# Re-key after adding a new public key
+ragenix -r
+
+# View decrypted (careful!)
+age -d -i ~/.config/age/keys.txt secrets/env.age
+```
+
+## Troubleshooting
+
+### "cannot decrypt: no valid identity"
+
+Your age key isn't configured. Run:
+```bash
+./setup-dev.sh
+```
+
+### "error: flake.nix is not in git"
+
+Commit the flake files:
+```bash
+git add flake.nix package.nix camera-sdk.nix secrets.nix
+git commit -m "Add flake files"
+```
+
+### "experimental feature 'flakes' not enabled"
+
+Add to `~/.config/nix/nix.conf`:
+```
+experimental-features = nix-command flakes
+```

+# USDA Vision Secrets Management
+
+This directory contains encrypted secrets managed by [ragenix](https://github.com/yaxitech/ragenix).
+
+## Setup
+
+1. **Generate an age key** (if you don't have one):
+   ```bash
+   # Generate a new age key
+   age-keygen -o ~/.config/age/keys.txt
+   
+   # Or convert your SSH key
+   ssh-to-age < ~/.ssh/id_ed25519.pub
+   ```
+
+2. **Add your public key to `secrets.nix`**:
+   ```nix
+   {
+     publicKeys = [
+       "age1..." # Your age public key
+       "ssh-ed25519 ..." # Or your SSH public key
+     ];
+   }
+   ```
+
+3. **Create and encrypt environment files**:
+   ```bash
+   # Create the encrypted .env file
+   ragenix -e secrets/env.age
+   
+   # Create the encrypted .env.azure file
+   ragenix -e secrets/env.azure.age
+   ```
+
+## Usage in Development
+
+In the development shell:
+```bash
+# Edit encrypted secrets
+ragenix -e secrets/env.age
+
+# Re-key secrets after adding a new public key
+ragenix -r
+```
+
+## Usage in NixOS
+
+The flake's NixOS module automatically handles decryption:
+
+```nix
+{
+  services.usda-vision = {
+    enable = true;
+    secretsFile = config.age.secrets.usda-vision-env.path;
+  };
+
+  age.secrets.usda-vision-env = {
+    file = ./usda-vision/secrets/env.age;
+    mode = "0644";
+  };
+}
+```
+
+## Files
+
+- `secrets.nix` - Public keys configuration
+- `env.age` - Encrypted main .env file
+- `env.azure.age` - Encrypted Azure OAuth configuration
+- `README.md` - This file
+
+## Security Notes
+
+- Never commit unencrypted `.env` files
+- Keep your age private key secure (`~/.config/age/keys.txt`)
+- The `.age` encrypted files are safe to commit to git
