 #### Data persistence
 Configure these options if you want to change default paths for data persistence:
-- `ConnectionStrings:DataContext=Data Source=/persistence/data.db` - SQLite DB connection string (default: `/persistence/data.db`)
-- `LettuceEncrypt:CertificatesPath=/persistence` - path to store Let's Encrypt certificates (default: `/persistence` for `Production` and `data.db` for `Development`)
+- `ConnectionStrings:DataContext=Data Source=/persistence/data.db` - SQLite DB connection string (default: `Data Source=/persistence/data.db` for `Production` and `Data Source=data.db` for `Development`)
+- `LettuceEncrypt:CertificatesPath=/persistence` - path to store Let's Encrypt certificates (default: `/persistence`)
 
 > **IMPORTANT**: default persistence paths are configured to be used in a Docker container, where the user is `root`. `/persistence` is not writtable by a non-root user, so you need either to change the paths if you want to run the app outside of a container without root privileges or run app as `sudo`.
