+# APT-OSTree Documentation

-## Overview
+Welcome to the APT-OSTree documentation! This guide will help you understand, install, and use APT-OSTree for managing packages in Debian/Ubuntu-based OSTree systems.

-apt-ostree is a Debian/Ubuntu equivalent of rpm-ostree, providing a hybrid image/package system that combines the strengths of APT package management with OSTree's atomic, immutable deployment model.

-
-## Bootc Integration
-
-### Why Bootc?
-
-Bootc is essential for the **Aurora-style workflow** - a modern approach to system deployment that treats operating systems as container images. This enables:
-
- **Container-native deployments**: Deploy systems like containers
- **Atomic updates**: Transactional system updates with rollback
- **Immutable infrastructure**: Predictable, reproducible deployments
- **Cloud-native workflows**: Integration with container registries and CI/CD
-
-### Installing Bootc
-
-Bootc is available as a Debian package from the Forgejo repository:
-
-```bash
-# Add the Forgejo repository
-curl -fsSL https://git.raines.xyz/api/packages/robojerk/debian/repository.key | sudo gpg --dearmor -o /usr/share/keyrings/forgejo-robojerk.gpg
-echo "deb [signed-by=/usr/share/keyrings/forgejo-robojerk.gpg] https://git.raines.xyz/api/packages/robojerk/debian noble main" | sudo tee /etc/apt/sources.list.d/forgejo-robojerk.list
-
-# Update package lists
-sudo apt update
-
-# Install libostree 2025.2-1 packages (required dependency)
-sudo apt install -y libostree-dev=2025.2-1~noble1 libostree-1-1=2025.2-1~noble1
-
-# Install bootc
-sudo apt install -y bootc
-```
-
-### Aurora-Style Workflow with apt-ostree
-
-The complete Aurora-style workflow combines apt-ostree and bootc:
-
-```bash
-# 1. Create OSTree commit with apt-ostree
-sudo apt-ostree install nginx apache2
-
-# 2. Build OCI image from commit
-apt-ostree compose build-chunked-oci --rootfs /var/lib/apt-ostree/repo --output my-system:latest --bootc
-
-# 3. Deploy with bootc
-bootc install oci:my-system:latest
-
-# 4. Boot into new deployment
-bootc status
-```
-
-### Bootc Package Repository
-
-The bootc package is maintained in a separate repository:
- **Repository**: [bootc-deb](https://git.raines.xyz/robojerk/bootc-deb)
- **Package**: [bootc 1.5.1-1~noble1](https://git.raines.xyz/robojerk/-/packages/debian/bootc/1.5.1-1~noble1)
- **Dependencies**: libostree-1-1 (>= 2025.2), systemd, podman|docker.io, skopeo
