hi! 
i added the about text, how it works page, some validation on pin word length and description length. also added testing (rspec) but need to add the actual tests. haven't used devise before so figuring out how the routing is exposed with symbols through `bundle exec rake routes' but that's a different story. making this pull request so you can at least have some say or be aware we're trying to make this happen. feel free to put as little or as much energy you want into this.
