- Notes

One can now create an account in a free git repository with private and public projects. There are many options for this nowadays, but the most popular are still github and bitbucket. You can find bitbucket at:
http://bitbucket.org
You can just upload your ssh keys and you're ready to go.
For example: 
git init
git add .
git commit -m "initial import"
git remote add origin_1  git@bitbucket.org:esguerra/end2end.git
git push origin_1 master
One can also create an empty git repository like so: 
mkdir nameofrepo
cd nameofrepo
git --bare init
You can also add an additional option to make sure that the repo is shared to all members of the same group with: 
git init --bare --shared=group
Once you've created the empty bare repo in a remote host, then you have to make your local project indexed by git and then you can push it to the bare git repository in your remote host. 
cd project   #AT LOCAL MACHINE
git init
git add
git commit -a
git push ssh://myremotehost/~/nameofrepo master #AND THIS WILL PUSH TO REMOTE
Note: In the last line notice that the push is done to master branch. If you want it to go automatically to your git repo, you gotta config .git/config first.

Tips of the day

If you did: 

git add .

And you really didn't mean to, then you can revert with: 

git reset

Then you will get to see again everything as unstaged, phew!
