 However there are times when we need to manually add a child relation to be inspected. This can be done in one of two ways. The most common case is if we want to specify additional associations. This will take all of the associations that can be auto-detected and also add in the one provided.
 
 ```ruby
 class SomeObject
-  include Hierarched
+  include Hierarchable
   hierarched parent_source: :parent,
              additional_descendant_associations: [:some_association]
 end
 ```
 
 There may also be a case when we want exact control over what associations that should be used. In that case, we can specify it like this:
 
 ```ruby
 class SomeObject
-  include Hierarched
+  include Hierarchable
   hierarched parent_source: :parent,
              descendant_associations: [:some_association]
 end
 ```
