+### Pleroma Settings Store
+Pleroma has mechanism that allows frontends to save blobs of json for each user on the backend. This can be used to save frontend-specific settings for a user that the backend does not need to know about.
+
+The parameter should have a form of `{frontend_name: {...}}`, with `frontend_name` identifying your type of client, e.g. `pleroma_fe`. It will overwrite everything under this property, but will not overwrite other frontend's settings.
+
+This information is returned in the `verify_credentials` endpoint.
+
