-# Updating guide
-
-## From v1.x to 2.x (or latest)
-
-Configuration handling has been updated: the ability to change settings from the CLI or the environment has been removed.
-
-**Configuration is now handled with a yml config file**, which can be overridden with the `--config` CLI argument.
-
-Here is the mapping from old cli argument / env variables to the new config file object:
-
-- accesstoken => `backend.accessToken`
-- webdav => `backend.enableWebdav`
-- disablesmallestscreen => `frontend.showSmallestScreenIndicator`
