Adding multiple remotes for a single git repository

It is sometimes useful to make multiple remote copies of a git repository, for instance, pushing your changes to both GitLab and GitHub. This can easily be done by calling the following commands:

git remote add gitlab url-to-your-gitlab-repository
git remote add github url-to-your-github-repository

The url-to-your-gitlab/github-repository part assumes that you already have created an empty repository in GitLab/GitHub. Now we are ready to push the latest changes using:

git push gitlab branch-name
git push github branch-name

where the branch-name variable refers to the actual name of the branch you need to push.
