 > 🪬 **IMPORTANT**: A Supabase instance is needed for the bot to work. A free cluster should be more than enough (even for small bots & communities) for development.
 
-There's a `supabase/schema.sql` file with the necessary tables and columns needed for the bot to work. You can use it to create the tables in your Supabase instance.
+### Supabase Local Development.
+
+Supabase is used for storing the bot's configs, guilds, and users.
+
+You can work with supabase local, just follow the instructions [here 🔗](https://supabase.io/docs/guides/local-development).
+Once you run `supabase start` the local supabase will be populate with the latest schema (have a look at the `supabase/seed.template.sql` file for more configuration)
 
 More information related to working with Supabase local development can be found [📹 here 🔗](https://www.youtube.com/watch?v=N0Wb85m3YMI)
 
 ## 👩🏼‍💻 Development
 
+Once the `Prepare environment` section is done, you can start developing your bot.
+
 ### `npm run dev`
 
 Will start a development server with `ts-node` and `nodemon` for livereload. A bot Invite link will be displayed in the console. Use it to invite the bot to your server.
