+#### Optional Series Folder Format for the Plex TV Series Scanner
+
+This naming scheme is made to be compatible with the beta [Plex TV Series Scanner](https://forums.plex.tv/t/beta-new-plex-tv-series-scanner/696242){:target="_blank" rel="noopener noreferrer"} that now support IMDB and TVDB IDs in file names.
+
+```bash
+{Series TitleYear} [imdb-{ImdbId}]
+```
+
+RESULT:
+
+`The Series Title! (2010) [imdb-tt1520211]`
+
+!!! note
+    The officially supported format is `{imdb-{ImdbId}}` but plex should also support `(imdb-{ImdbId})` or `[imdb-{ImdbId}]`, though the above should work for now. IMDb IDs are going to be very accurate and rarely change, TVDB/TMDB IDs, on the other hand, do change or are removed more frequently.
+
+!!! info
+    It's actually not needed to add a ID to the folder or filename to use the beta Plex TV Series Scanner.
