-# M2B - Mastodon ➡️ Bluesky crossposter
+# M2B - Mastodon ➡️ Bluesky crossposter
+
+FYI: This is a work-in-progress and I intend to clean up the code and make this *MUCH* more user-friendly.
+
+## Why did I make this?
+
+I was having a hard time finding a mastodon --> bluesky crossposting tool that supported replies and boosts on top of normal posts. This ended up wasting enough time to where I figured I'd just make my own.
+
+## How to use
+
+Don't forget to install dependencies with `npm i` and adjust the config by copying `example.env` into `.env`.
+Get the mastodon credentials from going to user preferences > development > and creating a new application.
+For bluesky credentials you have to make a new app password under settings > privacy and security > app passwords.
+This should ideally be run from a cron job (specifically `run.sh`), but can be run with just `node index.js`.
+
+## ToDo List
+
+* Cleanup code
+* Maybe fix the "reply to" add-in
+* Maybe generate image preview of mastodon post
