 ## How to make your own
 
+### Deploy to Koyeb
+
+> [!IMPORTANT]
+> You'll have to expand the "Environment variables and files" section and update the env variables before hitting the deploy button.
+
+> [!NOTE]
+> This deploys the **latest docker release and NOT the latest commit**. Since it uses prebuilt docker container, the deploy speed will be significantly faster.
