 This information is refreshed in the same manner that changesets are retrieved: By default, the repository is refreshed when a user visits the repository page. This information is cached for the time configured under the global `administration settings → repositories`.
 
-It could also externally be refreshed by using a cron job using the Sys API. Executing a GET against `/sys/projects/:identifier/repository/update_storage` will cause a refresh when the maximum cache time is expired. If you pass the query `?force=1` to the request above, it will ignore the cache.
-
-For a future release, we are hoping to provide a webhook to update changesets and storage immediately after a change has been committed to the repository.
