Getting Started
Choose an installation method and app-specific instructions from the setup documentation. The project documents a Docker image option; consult the README and documentation for current configuration details.
Considerations
- Themes are app-specific, so check the documentation to confirm that your application is supported and follow its instructions.
- Custom CSS changes presentation rather than app functionality, and compatibility may depend on the app's interface.
- Some entries in the project list are marked deprecated. Check the documentation before relying on a particular theme.
- The repository provides setup documentation and a Docker image, but the exact installation steps depend on the app and deployment method.
