 SQLite, as the name implies, is the lightest database type that GoToSocial can use. It stores entries in a simple file format, usually in the same directory as the GoToSocial binary itself. SQLite is great for small instances and lower-powered machines like Raspberry Pi, where a dedicated database would be overkill.
 
-To configure GoToSocial to use SQLite, change `db-type` to `sqlite`. The `address` setting will then be a filename instead of an address, so you might want to change it to `sqlite.db` or something similar.

 Note that the `:memory:` setting will use an *in-memory database* which will be wiped when your GoToSocial instance stops running. This is for testing only and is absolutely not suitable for running a proper instance, so *don't do this*.
