+### Creating Releases
+
+**Using Docker (Recommended - No Root Required):**
+
+Build release packages locally using Docker without needing root privileges:
+
+```bash
+# Build a release package
+./scripts/docker-release.sh v1.0.0
+
+# The release ZIP will be in release/sparkos-release.zip
+# This is identical to what GitHub Actions creates
+```
+
+**Creating a GitHub Release:**
+
+1. **Commit and push your changes** to the main branch
+2. **Create and push a version tag:**
+   ```bash
+   git tag v1.0.0
+   git push origin v1.0.0
+   ```
+3. **GitHub Actions will automatically:**
+   - Build the init binary
+   - Create the release package ZIP
+   - Build and publish Docker images (AMD64 + ARM64)
+   - Create a GitHub Release with the artifacts
+   - Publish to GitHub Container Registry
+
+The release will be available at:
+- **GitHub Releases:** https://github.com/johndoe6345789/SparkOS/releases
+- **Docker Images:** `ghcr.io/johndoe6345789/sparkos:v1.0.0`
+
+**Manual Release Creation:**
+
+You can also create a release manually:
+1. Go to https://github.com/johndoe6345789/SparkOS/releases/new
+2. Choose or create a tag (e.g., `v1.0.0`)
+3. Fill in the release title and description
+4. Upload the `sparkos-release.zip` (built locally with `docker-release.sh`)
+5. Publish the release

+# SparkOS Release Package
+
+This package contains the compiled SparkOS init system and all necessary files to run or build SparkOS.
+
+## Contents
+
+- `init` - The compiled init binary (statically linked)
+- `src/` - Source code for the init system
+- `scripts/` - Build and setup scripts
+- `config/` - Configuration files
+- `rootfs/` - Root filesystem structure
+- `Dockerfile` - Docker image definition
+- `Makefile` - Build system
+- Documentation files (README.md, ARCHITECTURE.md, etc.)
+
+## Quick Start
+
+### Using the Pre-built Binary
+
+The `init` binary is already compiled and ready to use:
+
+```bash
+# Copy to your rootfs
+cp init /path/to/your/rootfs/sbin/init
+chmod 755 /path/to/your/rootfs/sbin/init
+```
+
+### Using Docker
+
+The easiest way to test SparkOS:
+
+```bash
+# Build the Docker image
+docker build -t sparkos .
+
+# Run the test environment
+docker run --rm sparkos
+```
+
+### Rebuilding from Source
+
+If you need to rebuild:
+
+```bash
+# Build the init system
+make init
+
+# Install to rootfs
+make install
+```
+
+## Using Docker for Releases
+
+Build release artifacts without needing root or special tools:
+
+```bash
+# Build release package
+./scripts/docker-release.sh v1.0.0
+
+# The release package will be in release/sparkos-release.zip
+```
+
+## System Requirements
+
+- Linux system with kernel 3.x or later
+- Busybox for shell and utilities
+- For building: Docker or GCC compiler and Make
+
+## Documentation
+
+See README.md for complete documentation, including:
+- Building instructions
+- Docker usage
+- Network configuration
+- Development guidelines

+          SparkOS Bootable Disk Image
+          ===========================
+          
+          This package contains a compressed bootable disk image for SparkOS.
+          
+          Files:
+          - sparkos.img.gz - Compressed ext4 filesystem image (512MB)
+          
+          Quick Start:
+          -----------
+          
+          1. Decompress the image:
+             gunzip sparkos.img.gz
+          
+          2. Write to a USB drive (Linux):
+             sudo dd if=sparkos.img of=/dev/sdX bs=4M status=progress
+             sync
+             
+             WARNING: Replace /dev/sdX with your actual USB drive device.
+                      This will DESTROY all data on the target drive!
+          
+          3. Or mount and inspect:
+             sudo mount -o loop sparkos.img /mnt
+             ls -la /mnt
+             sudo umount /mnt
+          
+          Image Contents:
+          --------------
+          The image contains:
+          - SparkOS init system (/sbin/init)
+          - Basic filesystem structure (FHS compliant)
+          - Configuration files
+          
+          To make fully bootable:
+          ----------------------
+          The image needs additional components for booting:
+          1. Linux kernel (install to /boot/vmlinuz)
+          2. Busybox (install to /bin/busybox)
+          3. Bootloader (GRUB or syslinux)

+            **⚠️ WARNING**: Replace `/dev/sdX` with your actual USB device. This will erase all data on the target drive!
+            
+            ### Inspect the Image
+            
+            ```bash
+            # Mount and inspect
+            sudo mount -o loop sparkos.img /mnt

+# SparkOS Release Guide
+
+This guide explains how to create and publish releases for SparkOS.
+
+## Release Methods
+
+SparkOS supports two ways to create releases:
+
+1. **Automatic (Recommended)**: Push a version tag to trigger GitHub Actions
+2. **Manual**: Build locally and upload to GitHub
+
+## Method 1: Automatic Release (Recommended)
+
+This method uses GitHub Actions to automatically build and publish releases.
+
+### Prerequisites
+
+- Push access to the repository
+- All changes committed and pushed to `main` branch
+
+### Steps
+
+1. **Ensure everything is ready**
+   ```bash
+   # Make sure you're on main and up to date
+   git checkout main
+   git pull origin main
+   
+   # Verify the build works
+   make init
+   ```
+
+2. **Create and push a version tag**
+   ```bash
+   # Create a tag (use semantic versioning: v1.0.0, v2.1.3, etc.)
+   git tag v1.0.0
+   
+   # Push the tag to GitHub
+   git push origin v1.0.0
+   ```
+
+3. **Wait for GitHub Actions**
+   - Go to https://github.com/johndoe6345789/SparkOS/actions
+   - Two workflows will run:
+     - **"Build and Release"**: Creates the release ZIP
+     - **"Docker Build and Publish"**: Publishes Docker images
+   - Both should complete successfully (green checkmarks)
+
+4. **Verify the release**
+   - Go to https://github.com/johndoe6345789/SparkOS/releases
+   - Your new release should appear with `sparkos-release.zip` attached
+   - Docker images are available at `ghcr.io/johndoe6345789/sparkos:v1.0.0`
+
+### What Gets Published
+
+When you push a version tag, GitHub Actions automatically:
+
+- ✅ Builds the init binary (statically linked)
+- ✅ Creates a release package ZIP containing:
+  - Compiled init binary
+  - Complete source code
+  - Build scripts and configuration
+  - Root filesystem structure
+  - Full documentation
+- ✅ Creates a GitHub Release at `/releases`
+- ✅ Builds multi-architecture Docker images (AMD64 + ARM64)
+- ✅ Publishes Docker images to GitHub Container Registry
+- ✅ Tags Docker images with version number
+
+## Method 2: Manual Release
+
+Use this method if you need to build releases locally without pushing tags.
+
+### Prerequisites
+
+- Docker installed locally
+- `zip` utility installed
+
+### Steps
+
+1. **Build the release package using Docker**
+   ```bash
+   # Build for a specific version
+   ./scripts/docker-release.sh v1.0.0
+   
+   # Or use Make
+   make docker-release
+   
+   # The package will be created at: release/sparkos-release.zip
+   ```
+
+2. **Verify the package**
+   ```bash
+   # Check the file was created
+   ls -lh release/sparkos-release.zip
+   
+   # List contents
+   unzip -l release/sparkos-release.zip | head -40
+   ```
+
+3. **Create a GitHub Release manually**
+   - Go to https://github.com/johndoe6345789/SparkOS/releases/new
+   - Fill in:
+     - **Tag**: Create a new tag (e.g., `v1.0.0`)
+     - **Title**: `SparkOS v1.0.0` (or similar)
+     - **Description**: List changes and features
+   - **Upload** the `sparkos-release.zip` file
+   - Click **"Publish release"**
+
+### What's Included
+
+The Docker-based release script creates the exact same package as GitHub Actions:
+
+- Compiled init binary (statically linked, ready to use)
+- Complete source code
+- Build scripts (including `docker-release.sh`)
+- Configuration files
+- Root filesystem structure
+- Full documentation (README, ARCHITECTURE, CONTRIBUTING)
+
+## Testing Before Release
+
+Always test your changes before creating a release:
+
+### Test the Build
+
+```bash
+# Test compilation
+make clean && make init
+
+# Verify the binary
+file init
+ldd init  # Should show "not a dynamic executable" (static)
+```
+
+### Test with Docker
+
+```bash
+# Build the Docker image
+docker build -t sparkos:test .
+
+# Run the test environment
+docker run --rm sparkos:test
+
+# Or use Docker Compose
+docker-compose up
+```
+
+### Test the Release Script
+
+```bash
+# Build a test release package
+./scripts/docker-release.sh test
+
+# Verify it was created
+ls -lh release/sparkos-release.zip
+```
+
+## Release Checklist
+
+Before creating a release:
+
+- [ ] All changes are committed and pushed to `main`
+- [ ] Build succeeds: `make init` works
+- [ ] Docker build succeeds: `docker build -t sparkos:test .` works
+- [ ] Documentation is up to date (README, ARCHITECTURE, etc.)
+- [ ] Version follows semantic versioning (vMAJOR.MINOR.PATCH)
+- [ ] CHANGELOG or release notes are prepared (if applicable)
+
+## Troubleshooting
+
+### GitHub Actions Fails
+
+1. Check the workflow logs at https://github.com/johndoe6345789/SparkOS/actions
+2. Common issues:
+   - Build errors: Check if `make init` works locally
+   - Permission errors: Ensure `contents: write` permission in workflow
+   - Docker errors: Verify Dockerfile builds locally
+
+### Release Not Created
+
+- Ensure you pushed a tag starting with `v` (e.g., `v1.0.0`)
+- Check that the workflow has `contents: write` permissions
+- Verify the workflow completed successfully (green checkmark)
+
+### Docker Images Not Published
+
+- Check the "Docker Build and Publish" workflow logs
+- Ensure the tag was pushed (not just created locally)
+- Verify `packages: write` permission in workflow
+
+## Version Numbering
+
+Use semantic versioning for releases:
+
+- **v1.0.0**: First stable release
+- **v1.1.0**: New features, backward compatible
+- **v1.1.1**: Bug fixes only
+- **v2.0.0**: Breaking changes
+
+## Release Artifacts
+
+Each release includes:
+
+1. **GitHub Release Page**
+   - Release notes
+   - Downloadable `sparkos-release.zip`
+   - Link to Docker images
+
+2. **Docker Images** (automatically published)
+   - `ghcr.io/johndoe6345789/sparkos:v1.0.0` (specific version)
+   - `ghcr.io/johndoe6345789/sparkos:1.0` (minor version)
+   - `ghcr.io/johndoe6345789/sparkos:1` (major version)
+   - `ghcr.io/johndoe6345789/sparkos:latest` (if released from main)
+
+3. **Multi-Architecture Support**
+   - Linux AMD64 (x86_64)
+   - Linux ARM64 (aarch64)
+
+## Next Steps
+
+After releasing:
+
+1. Announce the release (if applicable)
+2. Update documentation links to point to the new version
+3. Test the release on different platforms
+4. Monitor for issues and prepare patches if needed
+
+## Support

+            **⚠️ WARNING**: Replace `/dev/sdX` with your actual USB device (e.g., `/dev/sdb`). This will **ERASE ALL DATA** on the target drive!
+            
+            ### Boot Instructions
+            
+            1. Insert the USB drive into a UEFI-capable system
+            2. Enter BIOS/UEFI settings (usually F2, F12, DEL, or ESC at boot)
+            3. Select the USB drive as boot device
+            4. SparkOS will boot automatically after 3 seconds
+            
+            ### Inspect Partitions (Advanced)
             
             ```bash
-            # Write to USB drive (Linux - BE CAREFUL!)
-            sudo dd if=sparkos.img of=/dev/sdX bs=4M status=progress
-            sudo sync

+            
+            # Mount ESP (EFI System Partition)
+            sudo mount ${LOOP_DEV}p1 /mnt
+            ls -la /mnt/EFI  # View bootloader and kernel
+            sudo umount /mnt
+            
+            # Mount root partition

+            # Cleanup
+            sudo losetup -d $LOOP_DEV
             ```
             
-            **⚠️ WARNING**: Replace `/dev/sdX` with your actual USB device. This will erase all data on the target drive!
+            ## Technical Details

+SparkOS UEFI-Bootable Image
 
-This is a minimal ext4 filesystem image containing the SparkOS init system.
-This is NOT a fully bootable image - it requires additional components.
+This is a UEFI-bootable disk image with:
+- GPT partition table
+- EFI System Partition (ESP) with FAT32 filesystem
+- GRUB UEFI bootloader
+- Linux kernel
+- SparkOS init system
+- Busybox utilities
 
-What's included:
-- SparkOS init binary (/sbin/init)
-- Basic FHS-compliant directory structure
-- Basic configuration files
+The image can be written to a USB drive and booted on UEFI systems:
+  sudo dd if=sparkos.img of=/dev/sdX bs=4M status=progress
+  sudo sync
 
-To make this fully bootable, you need to add:
-1. Linux kernel (install to /boot/vmlinuz)
-2. Busybox (install to /bin/busybox and create symlinks)
-3. Bootloader (GRUB or syslinux)
-4. Required libraries (if using dynamically linked binaries)
-
-This image can be mounted to extract the init binary or inspect the structure:
-  sudo mount -o loop sparkos.img /mnt
-  cp /mnt/sbin/init ./
-  sudo umount /mnt
+Boot options:
+- UEFI boot support (tested on x86_64 systems)
+- Automatic boot after 3 seconds
+- Console on tty1
