Mention constraints in your gem description for searchability

[leonid-shevtsov]

Hi! Thanks for this gem and thanks for your continued maintenance of it! It's super valuable.

However I almost missed it when searching for "constraints" on Rubygems. (Fortunately, later I found the Github page with Google.)

This is easy to fix - Rubygems searches in names and descriptions only, so include constraints into the description somewhere - and then more people will be able to find the gem.

Thanks, that's a great suggestion!
