Excuse me I am a total beginer, but I want to learn programming in RoR. I have linux Ubuntu 14.04. How I can install it? Is there somewhere step by step instruction? Thanks.
You can start with installing ruby . http://rvm.io/
I recommend using rvm http://rvm.io, all you need to do is, in a terminal sudo apt-get install curl curl -L https://get.rvm.io | bash -s stable --rails
then to stop rubygems installing docs for everything
echo "gem: --no-ri --no-rdoc" >> ~/.gemrc
Then work right through railstutorial.org (which is free to use online) or a similar tutorial.
Good luck
Colin
