Git

Tried Git\Github.
After github registration, you need only three commands to upload:
git add .
git commit -m 'write smth here'
git remote add origin git@github.com:username_at_github/projectname_at_github.git
#here you've got to create "projectname_at_github" repository at github. #Unfortunately, I only know how to do that with web interface.
git push origin

and 'git pull' to sync with remote server

also, I've created .gitignore  for not commiting .pycfiles:
*.pyc


Next, I need to try branching. Also, I've found a link with tutorials and pictures
