description: This guide teaches you how to set up an online MongoDB database for LibreChat using MongoDB Atlas, a cloud-based service. You will learn how to create an account, a project, and a cluster, as well as how to configure your database credentials, network access, and connection string.
- The URI format is `mongodb+srv://<username>:<password>@<host>/<database>?<options>`. Make sure to replace `<password>` with the database password you created in the "[database credentials](#database-credentials)" section above. Do not forget to remove the `<``>` around the password. Also remove `&w=majority` at the end of the connection string. `retryWrites=true` is the only option you need to keep. You should also add `LibreChat` or your own `APP_TITLE` as the database name in the URI.
