+##  Planning  ##
+
+Right now a lot of the planning for this project takes place in our development Discord, or through GitHub Issues and Projects.
+We're working on ways to improve the planning structure and better solicit feedback, and if you feel like you can help in this respect, feel free to give us a holler.
+
+##  Documentation  ##

+The documentation for this repository is available at [`glitch-soc/docs`](https://github.com/glitch-soc/docs) (online at [glitch-soc.github.io/docs/](https://glitch-soc.github.io/docs/)).
+Right now, we've mostly focused on the features that make this fork different from upstream in some manner.
+Adding screenshots, improving descriptions, and so forth are all ways to help contribute to the project even if you don't know any code.
+
+##  Frontend Development  ##
