 # NewPipeWithMoreServices
-An unofficial fork of NewPipe aiming to provide more services.
+
+An unofficial fork of [NewPipe](https://github.com/TeamNewPipe/NewPipe) aiming to provide more services.
+
+## Current Extra Services List:
+
+- Bilibili
+
+- Niconico
+
+## Contribute
+
+Any service is welcome as they don't contain R-18G things. Feel free to make your PR!
+
+## Note
+
+This repo is **NOT** the orginal repo of Newpipe, and will **NOT** always keep up with the latest version of the original repo.
+
+This repo can **NOT** ensure every extra service is available. If a service fails to work, it will stay failing until a kind (or maybe new) maintainer repairs
+it.
