@@ -49,14 +49,17 @@ This project has two components:
 1. **server:** contains the implementation of [tachiyomi's extensions library](https://github.com/tachiyomiorg/extensions-lib) and uses an Android compatibility library to run apk extensions. All this concludes to serving a REST API to `webUI`.
 2. **webUI:** A react SPA project that works with the server to do the presentation.
