+This Source enables multi-scrobbler to accept scrobbles from outside applications as if it was a Last.fm server.
+
+:::tip[Other Uses]
+
+* To **scrobble to** Last.fm, create a [Last.fm (Client)](/configuration/clients/lastfm)
+* To monitor and re-scrobble activity from your Last.fm account, create a [Last.fm (Source)](/configuration/sources/lastfm-source)
+
+:::
+
+### URL
+
+If a **slug** is **not** provided in configuration then multi-scrobbler will accept Last.fm scrobbles at
+
+```
+http://localhost:9078/2.0/
+```
+
+which is the "standard" Last.fm server path for scrobbling
+
+Use a slug only if you need to setup multiple Last.fm Endpoint sources and cannot use different tokens.
+
+If a slug is used then the URL will be:
+
+```
+http://localhost:9078/api/lastfm/mySlug
+```
