+#### Components
+
+You can match generic components similarly to [extra attributes](#extra-attributes). If you want to match an extra
+attribute match directly using that, for better performance.
+
+You can specify a `path` and match similar to extra attributes, but in addition you can also specify a `component`. This
+variable is the identifier of a component type that will then be encoded to nbt and matched according to the `match`
+using a [nbt matcher](#nbt-matcher).

 #### Pet Data
 
 Filter by pet information. While you can already filter by the skyblock id for pet type and tier, this allows you to
