+# Composefs CI/CD Pipeline
+
+This repository contains the CI/CD pipeline for building and packaging `composefs` - a content-addressable filesystem for containers.
+
+## What's Included
+
+- **Dockerfile**: Builds composefs with meson/ninja and FUSE support
+- **CI Workflow**: Complete CI/CD pipeline that:
+  - Builds composefs from source
+  - Creates Debian packages
+  - Uploads to Forgejo Debian Registry
+  - Uses apt-cacher-ng for faster builds
+
+## Features
+
+- ✅ **Source Build**: Builds composefs from GitHub source
+- ✅ **Debian Packaging**: Creates proper .deb packages
+- ✅ **FUSE Support**: Includes FUSE filesystem support
+- ✅ **Registry Upload**: Automatically uploads to Forgejo
+- ✅ **Caching**: Uses apt-cacher-ng for faster builds
+- ✅ **Docker Integration**: Uses Docker for isolated builds
+
+## Usage
+
+The CI workflow will automatically:
+1. Clone the composefs source code
+2. Build it with meson/ninja
+3. Create a Debian package
+4. Upload to the Forgejo Debian Registry
+
+## Dependencies
+
+- `libc6 (>= 2.39)`
