Build me a Kotlin project for a manga reader extension repository like the one used with Mihon or Tachiyomi.

I want it to let users add the repo, see available sources, and keep everything organized so new extensions and fixes can be added easily. Make sure the project includes clear setup instructions, a simple way to publish or update the extension index, and good documentation for contributors who want to add a new source or fix a broken one.

Please keep it practical and maintainable, and match the style of an open source repo that people can clone, build, and contribute to. If you need current details about the extension repo format or publishing flow, look up the latest docs online and follow those.
