Configuration

Configuration is done through the use of environment variables.

!!! note If you create a db with certain settings and later change them, haiku.rag will detect incompatibilities (for example, if you change embedding provider) and will exit. You can rebuild the database to apply the new settings, see Rebuild Database.
