+- `Manual` is ignored by all of my applications and only for my personal use
+
+- `Manga` is for Komga:
+  - Komga doesn't automatically import, We just decided to give it its own category anyway
+
+While creating these categories, We _ONLY_ changed the name, no other field was changed, the files once completed, will still go into their own directory as shown below.
