 Jupiter uses an ORM called [Drizzle](https://orm.drizzle.team/) to interact with the database. In order to connect to the database, you will need to add the `DATABASE_URL` variable to your `.env` file.
 
-We're using Supabase as our database provider. You can create a supabase account [here](https://supabase.io/). Once you have created an account, you can create a new project and add the `DATABASE_URL` to your `.env` file. From a Supabase project, you can find the `DATABASE_URL` by navigating to the `Settings` tab and clicking on the `Database` tab.
+We're using Neon as our database provider. You can create a Neon account [here](https://neon.com/). Once you have created an account, you can create a new project and add the `DATABASE_URL` to your `.env` file. From a Neon project, you can find the `DATABASE_URL` by navigating to the `Dashboard` tab and clicking on the `Connect` button.
 
 The Nebula API is used for image storage. The `NEBULA_API_URL` variable should be set to `https://api.utdnebula.com/` and the `NEBULA_API_STORAGE_BUCKET` variable to `jupiter`. An API key and storage key should be requested from the project lead for the `NEBULA_API_KEY` and `NEBULA_API_STORAGE_KEY` variables.
