 # Catstodon
-
 ## Introduction
-
 This Mastodon fork is based on the [glitch-soc Fork of Mastodon](https://github.com/glitch-soc/mastodon).
+I intend to contribute some useful differences back to [glitch-soc](https://github.com/glitch-soc/mastodon) and [vanilla Mastodon](https://github.com/mastodon/mastodon).
 
-- To install, take a look at [glitch-soc.github.io/docs/](https://glitch-soc.github.io/docs/). The instructions and features are the same, except for the differences outlined below.
-- Contributing guidelines are available [here](CONTRIBUTING.md).

 ## Differences
-
 - Some files are adjusted specifically for the CatCatNya~ instance. Specifically, these:
   - sounds/boop.mp3
   - sounds/boop.ogg
-  
-  You might want to revert these to the upstream files (or your own versions!) if you decide to use this fork for your own instance.
