Gems gems gems!

One of the best features of the Ruby on rails is the use of gems! Sometimes it's hard to pick the best gems to get the work done. My first quest in the RoR world was find a lot of useful gem's to work with, and I want to share my finding. I really hope that this could be a good start for RoR starters. I'm in love with bootstrap so, many of this gems are compatible with it.


Bootstrap is a toolkit from Twitter designed to kickstart development of webapps and sites. It includes base CSS and HTML for typography, forms, buttons, tables, grids, navigation, and more.
