Here are some command line suggestions:
Code:
$ git status
git add <path/filename>
git add -u
git commit -m "<comment>"
git push
git push origin master
git push origin <branch-name>
Basically you should add new or modified files, these are the git add commands, and there are various options to choose.
Next you commit, using the commit, and typically with a comment.
Finally you push these changes to the repository. I find that typing "git push" first gives me advice back to tell me if I need the origin, etc. Sometimes yes, sometimes no. I don't know the full rules there, sorry, just my experiences.
Hope this helps.
