+# Red Hat/Fedora bootc-image-builder Documentation
+
+This directory contains documentation for the original Red Hat/Fedora version of bootc-image-builder.
+
+## 📚 Documentation Index
+
+### Core Documentation
+- **[Basic Usage Guide](usage.md)** - Getting started with bootc-image-builder
+- **[Advanced Usage Guide](usage-advanced.md)** - Deep dive into bootc-image-builder features
+
+### Technical Analysis
+- **[osbuild Architecture Analysis](osbuild-analysis/osbuild-architecture.md)** - Deep dive into osbuild internals
+
+## 🎯 Purpose
+
+These documents provide the foundation for understanding the original Red Hat/Fedora implementation of bootc-image-builder. They serve as:
+
+1. **Reference Material** - Understanding the original architecture and design
+2. **Migration Context** - Background for migrating to Debian version
+3. **Technical Foundation** - Base knowledge for osbuild stage development
+
+## 🔗 Related Documentation
+
+For Debian-specific implementation, see:
+- **[Debian Documentation](../debian-bootc-image-builder/docs/README.md)** - Debian fork documentation
+- **[Migration Guide](../debian-bootc-image-builder/docs/migration-guide.md)** - Migrate from Red Hat to Debian
+
+## 📖 Reading Order
+
+1. **[Basic Usage Guide](usage.md)** - Understand the core concepts
+2. **[Advanced Usage Guide](usage-advanced.md)** - Deep technical details
+3. **[osbuild Architecture Analysis](osbuild-analysis/osbuild-architecture.md)** - Technical foundation

+# Hacking on deb-bootc-image-builder
+
+Hacking on `deb-bootc-image-builder` should be fun and is easy.
+We have a bunch of unit tests and good integration testing
+(including cross-arch image build/testing) based on qemu and
+pytest.
+
+## Setup
+
+To work on deb-bootc-image-builder one needs a working Go environment. See
+[go.mod](bib/go.mod). 
+
+To run the testsuite install the test dependencies as outlined in the
+[github action](./.github/workflows/tests.yml) under
+"Install test dependencies".  Many missing test dependencies will be
+auto-detected and the tests skipped. However some (like podman or
+qemu) are essential.
+
+## Code layout
+
+The go source code of bib is under `./bib`. It uses the
+[images](https://github.com/osbuild/images) library internally to
+generate the bootc images. Unit tests (and integration tests where it
+makes sense) are expected to be part of a PR but we are happy to
+help if those are missing from a PR.
+
+The integration tests are located under `./test` and are written
+in pytest.
+
+ 
+## Build
+
+Build by running:
+```
+$ cd bib
+$ go build ./cmd/bootc-image-builder/
+```
+
+## Unit tests
+
+Run the unit tests via:
+```
+$ cd bib
+$ go test ./...
+```
+
+## Integration tests
+
+To run the integration tests ensure to have the test dependencies as
+outlined above. The integration tests are written in pytest and make
+heavy use of the pytest fixtures feature. They are extensive and will
+take about 45min to run (dependening on hardware and connection) and
+involve building/booting multiple images.
+
+To run them, change into the deb-bootc-image-build root directory and run
+```
+$ pytest -s -vv
+```
+for the full output.
+
+Run
+```
+$ pytest
+```
+for a more concise output.

+# Troubleshooting
+
+Common issues and solutions when working with deb-bootc-image-builder.
+
+## Build Issues
+
+### Go module download failures
+If you encounter issues with Go module downloads, ensure your GOPROXY is set correctly:
+```bash
+export GOPROXY=https://proxy.golang.org,direct
+```
+
+### Permission issues
+Some operations may require elevated privileges. Ensure you have the necessary permissions or use sudo where appropriate.
+
+## Runtime Issues
+
+### Container storage issues
+If you encounter container storage issues, check that the required volumes are properly mounted and accessible.
+
+### Package installation failures
+Ensure your Debian package sources are up to date:
+```bash
+apt-get update
+```
+
+## Test Issues
+
+### Integration test failures
+Integration tests require specific dependencies. Ensure all test dependencies are installed as outlined in the main README.
+
+### Cross-architecture build issues
+Cross-architecture builds require proper Go toolchain setup. Ensure GOOS and GOARCH are properly configured.
