-### gotosocial admin media list-local
+### gotosocial admin media list-attachments
 
-This command can be used to list local media. Local media is media that belongs to posts by users with an account on the instance.
+Can be used to list the storage paths of local, remote, or all media attachments on your instance (including headers and avatars).
 
-The output will be a list of files. The list can be used to drive your backups.
+`local-only` and `remote-only` can be used as filters; they cannot both be set at once.
 
-### gotosocial admin media list-remote
+If neither `local-only` or `remote-only` are set, all media attachments on your instance will be listed.
 
-This is the corollary to list-local, but instead lists media from remote instances. Remote media belongs to other instances, but was attached to a post we received over federation and have potentially cached locally.
+You may want to run this with `GTS_LOG_LEVEL` set to `warn` or `error`, otherwise it will log a lot of info messages you probably don't need.
 
-The output will be a list of URLs to retrieve the original content from. GoToSocial automatically retrieves remote media when it needs it, so you should never need to do so yourself.
