You created a local repo in your m/c and then want to push it to github
The github repo for your project has already been created on github.
Either you have created it or has been added as one of the collaborators.
When you create a project
$ rails new app1 --skip-active-record --skip-bundle
and want this to be associated to the repo
cd to the project folder,
$ cd app1
and then execute
$ git remote add origin email@example.com:analytics/app1.git
$git pull origin master
So, the local repo has been pushed to the remote github repo
