Recently I found deploying your Rails code which already on Github to Heroku is very useful. You can use this to show your work to your customers, friends …. Let’s start
== Generate a keypair
ssh-keygen -t rsa -C “firstname.lastname@example.org”
(enter at first prompt)
Then go to your github account then add that key in id_rsa.pub. Should use a text editor then ctrl-A to select all.
