 ## Quick Start
 
+### Using Docker (Recommended for Testing)
+
+The easiest way to test SparkOS is using the pre-built Docker image from GitHub Container Registry:
+
+```bash
+# Pull and run the latest image
+docker pull ghcr.io/johndoe6345789/sparkos:latest
+docker run --rm ghcr.io/johndoe6345789/sparkos:latest
+
+# Or build locally
+docker build -t sparkos:local .
+docker run --rm sparkos:local
+```
+
+The Docker image includes:
+- Pre-built init system binary
+- Minimal root filesystem structure
+- Test environment for validation
+
+Images are automatically built and published to [GitHub Container Registry](https://github.com/johndoe6345789/SparkOS/pkgs/container/sparkos) on every push to main branch.

 ## Development
 
+### CI/CD and Docker
+
+SparkOS uses GitHub Actions for continuous integration and delivery:
+
+**Automated Builds:**
+- Docker images are automatically built on every push to main/develop branches
+- Images are also built for pull requests (testing only, not published)
+- Tagged releases automatically create versioned Docker images
+
+**Container Registry:**
+- Images are published to GitHub Container Registry (GHCR)
+- Pull images: `docker pull ghcr.io/johndoe6345789/sparkos:latest`
+- Available tags: `latest`, `main`, `develop`, version tags (e.g., `v1.0.0`)
+
+**Docker Development:**
+```bash
+# Build Docker image locally
+docker build -t sparkos:dev .
+
+# Test the image
+docker run --rm sparkos:dev
+
+# Inspect the init binary
+docker run --rm sparkos:dev sh -c "ls -lh /sparkos/rootfs/sbin/init"
