 ## Common Problems
 
 ### Wrong categories
-Incorrect categories is probably the most common cause of results showing in manual searches of an indexer/tracker, but *not* in Sonarr. The indexer/tracker *should* show the category in the search results, which should help you figure out what is missing.
+Incorrect categories is probably the most common cause of results showing in manual searches of an indexer/tracker, but *not* in Sonarr. The indexer/tracker *should* show the category in the search results, which should help you figure out what is missing. If you're using Jackett, each tracker has a list of specifically supported categories. Make sure you're using the correct ones for each entry. I find it helpful to have the list visible in one browser window while I edit the entry in Sonarr.
 
 ### Wrong show type
 The show type is another cause of poor search results. Most shows should be `Standard`. For daily shows which are typically released with a date, `Daily` should be used. Finally, there is anime where using `Anime` is *usually* right, but sometimes `Standard` can work better, so try the *other* one if you're having issues.
