 ## How it works
 Settings are stored in database and are applied in `runtime` after each change. Most of the settings take effect immediately, except some, which need instance reboot. These settings are needed in `compile time`, that's why settings are duplicated to the file.
 
-File with duplicated settings is located in `config/{env}.exported_from_db.exs`. For prod env it will be `config/prod.exported_from_db.exs`.
+File with duplicated settings is located in `config/{env}.exported_from_db.exs` if pleroma is runned from source. For prod env it will be `config/prod.exported_from_db.exs`.

+For releases: `/etc/pleroma/prod.exported_from_db.secret.exs` or `PLEROMA_CONFIG_PATH/prod.exported_from_db.exs`.
