 ### Tag Support
 
-Games can be tagged with region, revision, or other tags by using parentheses in the file name. Additionally, you can set the region and language by adding a prefix: `(USA)`, `[reg-J]`, `(French)`, `[De]`.
+Games can be tagged with region, revision, or other tags by using parentheses in the file name. RomM will parse both tags with `[]` and `()`.
 
+- Regions and languages will be identified with both supported shortcodes and names. Additionally, you can set a custom region/language adding a `reg` prefix (e.g. `reg MyOwnLang`)
 - Revision tags must be prefixed with `rev` or `rev-` (e.g. `rev v1` or `rev-1`)
 - Other tags will also be imported, for example: `tetris [1.0001](HACK)[!].gba`
 
 Tags can be used to search for games in the search bar. For example, searching for `(USA)` will return all games with the USA tag.
