I'm trying to document my code using YARD, however I'm having hard time figuring out how to get rid of following warning:
   $ ~/.gem/ruby/2.3.0/bin/yard 
[warn]: @param tag has unknown parameter name: val 
    in file `lib/wolfsden_myanimelist/values.rb' near line 22
Files:           4
Modules:         2 (    2 undocumented)

Attributes:     14 (    0 undocumented)
Methods:         4 (    0 undocumented)
 66.67% documented
In the following code:
    # @overload episode
    #   Gets last seen episode.
    #   @return [Integer] last seen episode
    # @overload episode=(val)
    #   Sets last seen episode.
    #   @param val last seen episode
    attr_reader :episode
    def episode=(val)
        @status = Integer(val)
    end
However I believe this is exactly how documentation ( http://www.rubydoc.info/gems/yard/file/docs/GettingStarted.md#Documentation_for_a_Separate_Attribute_Writer ) recommends to do it. So, how can I get rid of the warning?
                        
I believe what you need to do is supply a data type for the parameter. It would look like this:
You can have more than one data type in a parameter -- I put
StringandIntegerin, because a user could put in either.
