-# ReVanced Releases API
-
 This is a simple API that returns the latest ReVanced releases.
 
 ## Usage
 
 The API is available at [https://revanced-releases-api.afterst0rm.xyz/](https://revanced-releases-api.afterst0rm.xyz/).
 
-For development purposes, you can run the API locally by cloning this repository and running `docker-compose up` or `docker-compose up --build` if you want to rebuild the image. Optionally you can run the application without Docker by running `pip -U install -r ./requirements.txt` and `python ./main.py`. Remember to set the environment variable `GITHUB_TOKEN` to a valid token if you want to run the API locally.

-### API Endpoints
+## API Endpoints
 
 * [apps](/apps) - Returns all currently patchable apps
 * [tools](/tools) - Returns the latest version of all ReVanced tools and Vanced MicroG
 * [patches](/patches) - Returns the latest version of all ReVanced patches
 
-There is no cache on this API because we trust our fellow developers to implement a cache on their end.
+## Additional Information
 
-So please be kind and don't blow up the API with requests or we will have to block your IP address.
+* Rate Limiting - 15 requests per minute
+* Cache - 1 minute
+
+## Important Notes
+
+1. Although we will try to avoid breaking changes, we can't guarantee that it won't happen.
+2. Okay, the api is now cached and rate limited (per endpoint). But please don't abuse it, we don't want to have to block you.
+3. Make sure to implement a cache system on your end to avoid unnecessary requests.
 
 Godspeed 💀
