 # bnuy-api
 
 A API which collects pictures of bunnies and provides a API to get random bunny pictures.
-doesn't work yet, still in progress
+
+it's just a basic API right now, I want to add more sources for gifs (tenor?) and maybe more sources for pictures
+
+# Usage
+
+The API is available [here](https://bnuy-api.scrunkly.cat/random)
+
+# Selfhosting
+
+Just copy the compose.yml from the repo and copy the .env.example to .env and fill it.
