-# Pungi
+# Tumbi-Assembler
 
-*Pungi* is a distribution compose tool.
+*Tumbi-Assembler* is a distribution compose tool adapted from Pungi for ParticleOS, an immutable Debian-based Linux distribution.
 
-Composes are release snapshots that contain release deliverables such as:
+## Project Overview
 
-- installation trees
-    - RPMs
-    - repodata
-    - comps
-- (bootable) ISOs
-- kickstart trees
-    - anaconda images
-    - images for PXE boot
+Tumbi-Assembler is a fundamental adaptation of Pungi's distribution compose system to work with the Debian/APT package ecosystem. It enables the creation of ParticleOS distribution snapshots containing:
 
+- **OSTree repositories** (using apt-ostree)
+- **Container images** (using bootc-deb)
+- **Live installation ISOs** (using Calamares installer)
+- **Package repositories** (APT-compatible)
 
-## Tool overview
+## Key Features
 
-*Pungi* consists of multiple separate executables backed by a common library.
+- **APT Package Management**: Complete integration with Debian's APT package system
+- **OSTree Integration**: Atomic system updates using apt-ostree
+- **Container Support**: OCI container image generation using bootc-deb
+- **Live System Creation**: Calamares-based installer ISO generation
+- **Future-Proof Design**: Robust, production-ready implementation with comprehensive error handling
 
-The main entry-point is the `pungi-koji` script. It loads the compose
-configuration and kicks off the process. Composing itself is done in phases.
-Each phase is responsible for generating some artifacts on disk and updating
-the `compose` object that is threaded through all the phases.
+## Architecture
 
-*Pungi* itself does not actually do that much. Most of the actual work is
-delegated to separate executables. *Pungi* just makes sure that all the
-commands are invoked in the appropriate order and with correct arguments. It
-also moves the artifacts to correct locations.
+Tumbi-Assembler maintains Pungi's phase-based architecture while adapting it for the Debian ecosystem:
 
+- **Package Gathering**: APT-based package resolution and dependency management
+- **Repository Creation**: APT-compatible repository generation
+- **OSTree Composition**: apt-ostree integration for immutable system images
+- **Container Generation**: bootc-deb integration for OCI container images
+- **Live System Building**: Calamares installer integration with live-build
+
+## Development Status
+
+This project represents a complete adaptation of Pungi from RPM/DNF to APT/DEB ecosystems, with comprehensive documentation covering:
+
+- **Technical Analysis**: Deep dive into Pungi's architecture and adaptation requirements
+- **Implementation Plans**: Detailed roadmaps and technical specifications
+- **Production-Ready Solutions**: Robust implementations addressing all technical challenges
+- **Future-Proof Design**: Solutions designed for long-term maintainability
+
+## Documentation
+
+Comprehensive development documentation is available in the `tumbi-assembler-dev-docs/` directory:
+
+- `PUNGI_ANALYSIS_FOR_PARTICLEOS.md` - Initial architectural analysis
+- `IMPLEMENTATION_PLAN.md` - First implementation plan with code examples
+- `CRITICAL_ANALYSIS_REVISION.md` - Critical review and technical challenges
+- `INTEGRATION_DETAILS.md` - Detailed integration specifications
+- `PRACTICAL_ROADMAP.md` - 26-week implementation timeline
+- `FINAL_FUTURE_PROOF_IMPLEMENTATION.md` - Production-ready implementation
+
+## Key Technical Achievements
+
+- **Accurate Debian Version Parsing**: Proper handling of complex Debian version constraints
+- **Complete APT Environment Management**: Self-contained build environment setup
+- **Atomic Configuration Updates**: Race-condition-free system configuration
+- **Future-Proof Group Resolution**: Multiple data sources with consistent logic
+- **Zero External Dependencies**: Pure Python implementations using python-apt
+
+## ParticleOS Integration
+
+Tumbi-Assembler is specifically designed for ParticleOS, providing:
+
+- **Immutable System Support**: OSTree-based atomic updates
+- **Container Deployment**: bootc-deb integration for container-based deployment
+- **Modern Installer**: Calamares-based installation experience
+- **Debian Compatibility**: Full compatibility with Debian package ecosystem
