I'm switching from PHP to Ruby on Rails and I'm loving it, the only thing is I'm so used to Twitter Bootstrap for most of my designs and now I feel crippled without it, I followed some tutorials like adding bootstrap-sass and what not to my Gemfile, but I still appear to be missing important things like input-block-level I'm just curious if there is an updated version or a easier tutorial to follow? Thanks.
AFAIK, the easiest and most rails way to integrate the twitter bootstrap to rails is via
twitter-bootstrap-rails gem, they have a pretty good documentation too.
check these screen casts, and this (premium) to get an idea.
and welcome to Rails :)
