Plugins reference guide

Will there be any area for reference guides for the various plugins in

Am specifically trying to find details for the logstash-input-http plugin ( Was hoping to find something similar to what's available for the output-http plugin ( but have not come across anything so far.

I know I could be picking a lesser-used edge case here, but the point is perhaps more to suggest incorporating the bigger or more commonly used plugins to the core documentation somehow. Or having a separate page for plugin documentation that would be built using files in the plugin repositories themsleves.
