I have now started work on this by creating the manifest.json file and some other boilerplate like a very small README.md and added the MIT license. Next I will start to look into how the main home page of Stardance gets posts and how I can add new stuff to it. Will start by doing a bookmarking feature (like adding a favorite button that you usually see on social media). This is my first time making an extension so it will hopefully be fun and interesting.
