[git] How to add a local repo and treat it as a remote repo

It appears that your format is incorrect:

If you want to share a locally created repository, or you want to take contributions from someone elses repository - if you want to interact in any way with a new repository, it's generally easiest to add it as a remote. You do that by running git remote add [alias] [url]. That adds [url] under a local remote named [alias].

#example
$ git remote
$ git remote add github [email protected]:schacon/hw.git
$ git remote -v
