+# GitHub Actions Workflows
+
+## Docker Image Publishing
+
+The `publish-docker.yml` workflow automatically builds and publishes Docker images for the backend service using Nix.
+
+### Triggers and Tagging Strategy
+
+| Event        | Condition                   | Published Tags         | Example           |
+|--------------|-----------------------------|------------------------|-------------------|
+| Tag push     | Tag pushed to `main` branch | `latest` + version tag | `latest`, `1.0.0` |
+| Branch push  | Push to `develop` branch    | `develop`              | `develop`         |
+| Pull request | PR opened or updated        | `pr<number>`           | `pr12`            |
+| Branch push  | Push to `main` (no tag)     | `latest`               | `latest`          |
+
+### Required GitHub Secrets
+
+Configure these secrets in your repository settings (`Settings` → `Secrets and variables` → `Actions`):
+
+| Secret Name         | Description                                 | Example Value                                   |
+|---------------------|---------------------------------------------|-------------------------------------------------|
+| `DOCKER_USERNAME`   | Username for Docker registry authentication | `phundrak` (Docker Hub) or `phundrak` (ghcr.io) |
+| `DOCKER_PASSWORD`   | Password or token for Docker registry       | Personal Access Token (PAT) or password         |
+| `CACHIX_AUTH_TOKEN` | (Optional) Token for Cachix caching         | Your Cachix auth token                          |
+
+#### For GitHub Container Registry (ghcr.io)
+
+1. Create a Personal Access Token (PAT):
+   - Go to GitHub Settings → Developer settings → Personal access tokens → Tokens (classic)
+   - Click "Generate new token (classic)"
+   - Select scopes: `write:packages`, `read:packages`, `delete:packages`
+   - Copy the generated token
+
+2. Add secrets:
+   - `DOCKER_USERNAME`: Your GitHub username
+   - `DOCKER_PASSWORD`: The PAT you just created
+
+#### For Docker Hub
+
+1. Create an access token:
+   - Go to Docker Hub → Account Settings → Security → Access Tokens
+   - Click "New Access Token"
+   - Set permissions to "Read, Write, Delete"
+   - Copy the generated token
+
+2. Add secrets:
+   - `DOCKER_USERNAME`: Your Docker Hub username
+   - `DOCKER_PASSWORD`: The access token you just created
+
+#### For Custom Registry (e.g., labs.phundrak.com)
+
+1. Obtain credentials from your registry administrator
+
+2. Add secrets:
+   - `DOCKER_USERNAME`: Your registry username
+   - `DOCKER_PASSWORD`: Your registry password or token
+
+### Configuring the Docker Registry
+
+The target registry is set via the `DOCKER_REGISTRY` environment variable in the workflow file. To change it:
+
+1. Edit `.github/workflows/publish-docker.yml`
+2. Modify the `env` section:
+
+```yaml
+env:
+  DOCKER_REGISTRY: ghcr.io  # Change to your registry (e.g., docker.io, labs.phundrak.com)
+  IMAGE_NAME: phundrak/phundrak-dot-com-backend
+```
+
+Or set it as a repository variable:
+- Go to `Settings` → `Secrets and variables` → `Actions` → `Variables` tab
+- Add `DOCKER_REGISTRY` with your desired registry URL
+
+### Image Naming
+
+Images are published with the name: `${DOCKER_REGISTRY}/${IMAGE_NAME}:${TAG}`
+
+For example:
+- `ghcr.io/phundrak/phundrak-dot-com-backend:latest`
+- `ghcr.io/phundrak/phundrak-dot-com-backend:1.0.0`
+- `ghcr.io/phundrak/phundrak-dot-com-backend:develop`
+- `ghcr.io/phundrak/phundrak-dot-com-backend:pr12`
+
+### Local Testing
+
+To test the Docker image build locally:
+
+```bash
+# Build the image with Nix
+nix build .#backendDockerLatest
+
+# Load it into Docker
+docker load < result
+
+# Run the container
+docker run -p 3100:3100 localhost/phundrak/backend-rust:latest
+```
+
+### Troubleshooting
+
+#### Authentication Failures
+
+If you see authentication errors:
+1. Verify your `DOCKER_USERNAME` and `DOCKER_PASSWORD` secrets are correct
+2. For ghcr.io, ensure your PAT has the correct permissions
+3. Check that the `DOCKER_REGISTRY` matches your credentials
+
+#### Build Failures
+
+If the Nix build fails:
+1. Test the build locally first: `nix build .#backendDockerLatest`
+2. Check the GitHub Actions logs for specific error messages
+3. Ensure all dependencies in `flake.nix` are correctly specified
+
+#### Image Not Appearing in Registry
+
+1. Verify the workflow completed successfully in the Actions tab
+2. Check that the registry URL is correct
+3. For ghcr.io, images appear at: `https://github.com/users/USERNAME/packages/container/IMAGE_NAME`
+4. Ensure your token has write permissions

 ### Prerequisites

+**Option 1: Native Development**
 - Rust (latest stable version recommended)
 - Cargo (comes with Rust)

+**Option 2: Nix Development (Recommended)**
+- [Nix](https://nixos.org/download) with flakes enabled
+- All dependencies managed automatically
+
 ### Running the Server

-To start the development server:
-
+**With Cargo:**
 ```bash
 cargo run
 ```

+**With Nix development shell:**
+```bash
+nix develop .#backend
+cargo run
+```
+
 The server will start on the configured port (default: 3100).

 ### Building

-For development builds:
+**With Cargo:**

+For development builds:
 ```bash
 cargo build
 ```

 For optimized production builds:
-
 ```bash
 cargo build --release
 ```

 The compiled binary will be at `target/release/backend`.

+**With Nix:**
+
+Build the backend binary:
+```bash
+nix build .#backend
+# Binary available at: ./result/bin/backend
+```
+
+Build Docker images:
+```bash
+# Build versioned Docker image (e.g., 0.1.0)
+nix build .#backendDocker
+
+# Build latest Docker image
+nix build .#backendDockerLatest
+
+# Load into Docker
+docker load < result
+# Image will be available as: localhost/phundrak/backend-rust:latest
+```
+
+The Nix build ensures reproducible builds with all dependencies pinned.

+## Docker Deployment
+
+### Using Pre-built Images
+
+Docker images are automatically built and published via GitHub Actions to the configured container registry.
+
+Pull and run the latest image:
+```bash
+# Pull from Phundrak Labs (labs.phundrak.com)
+docker pull labs.phundrak.com/phundrak/phundrak-dot-com-backend:latest
+
+# Run the container
+docker run -d \
+  --name phundrak-backend \
+  -p 3100:3100 \
+  -e APP__APPLICATION__PORT=3100 \
+  -e APP__EMAIL__HOST=smtp.example.com \
+  -e APP__EMAIL__PORT=587 \
+  -e APP__EMAIL__USER=user@example.com \
+  -e APP__EMAIL__PASSWORD=your_password \
+  -e APP__EMAIL__FROM="Contact Form <noreply@example.com>" \
+  -e APP__EMAIL__RECIPIENT="Admin <admin@example.com>" \
+  labs.phundrak.com/phundrak/phundrak-dot-com-backend:latest
+```
+
+### Available Image Tags
+
+The following tags are automatically published:
+
+- `latest` - Latest stable release (from tagged commits on `main`)
+- `<version>` - Specific version (e.g., `1.0.0`, from tagged commits like `v1.0.0`)
+- `develop` - Latest development build (from `develop` branch)
+- `pr<number>` - Pull request preview builds (e.g., `pr12`)
+
+### Building Images Locally
+
+Build with Nix (recommended for reproducibility):
+```bash
+nix build .#backendDockerLatest
+docker load < result
+docker run -p 3100:3100 localhost/phundrak/backend-rust:latest
+```
+
+Build with Docker directly:
+```bash
+# Note: This requires a Dockerfile (not included in this project)
+# Use Nix builds for containerization
+```
+
+### Docker Compose Example
+
+```yaml
+version: '3.8'
+
+services:
+  backend:
+    image: labs.phundrak.com/phundrak/phundrak-dot-com-backend:latest
+    ports:
+      - "3100:3100"
+    environment:
+      APP__APPLICATION__PORT: 3100
+      APP__EMAIL__HOST: smtp.example.com
+      APP__EMAIL__PORT: 587
+      APP__EMAIL__USER: ${SMTP_USER}
+      APP__EMAIL__PASSWORD: ${SMTP_PASSWORD}
+      APP__EMAIL__FROM: "Contact Form <noreply@example.com>"
+      APP__EMAIL__RECIPIENT: "Admin <admin@example.com>"
+      APP__EMAIL__STARTTLS: true
+      APP__RATE_LIMIT__ENABLED: true

+## CI/CD Pipeline
+
+### Automated Docker Publishing
+
+GitHub Actions automatically builds and publishes Docker images based on repository events:
+
+| Event Type      | Trigger                      | Published Tags                |
+|-----------------|------------------------------|-------------------------------|
+| Tag push        | `v*.*.*` tag on `main`       | `latest`, `<version>`         |
+| Branch push     | Push to `develop`            | `develop`                     |
+| Pull request    | PR opened/updated            | `pr<number>`                  |
+| Branch push     | Push to `main` (no tag)      | `latest`                      |
+
+### Workflow Details
+
+The CI/CD pipeline (`.github/workflows/publish-docker.yml`):
+
+1. **Checks out the repository**
+2. **Installs Nix** with flakes enabled
+3. **Builds the Docker image** using Nix for reproducibility
+4. **Authenticates** with the configured Docker registry
+5. **Tags and pushes** images based on the event type
+
+### Registry Configuration
+
+Images are published to the registry specified by the `DOCKER_REGISTRY` environment variable in the workflow (default: `labs.phundrak.com`).
+
+To use the published images, authenticate with the registry:
+
+```bash
+# For Phundrak Labs (labs.phundrak.com)
+echo $GITHUB_TOKEN | docker login labs.phundrak.com -u USERNAME --password-stdin
+
+# Pull the image
+docker pull labs.phundrak.com/phundrak/phundrak-dot-com-backend:latest
+```
+
+### Required Secrets
+
+The workflow requires these GitHub secrets:
+- `DOCKER_USERNAME` - Registry username
+- `DOCKER_PASSWORD` - Registry password or token
+- `CACHIX_AUTH_TOKEN` - (Optional) For Nix build caching
+
+See [.github/workflows/README.md](../.github/workflows/README.md) for detailed setup instructions.
