Git - Steps to commit a project

1. Show the status(how many new files, deleted files, modified files, etc.):

$ git status

2. Add all files to the project:

$ git add -A

the -A option means track all including deleted files.

3. Commit:

$ git commit -m "[Comments]"

the -m option gives you the possibility to add your comments in the same line.

4. Push:

$ git push -u origin master

The -u is optional and what it does is sets your local repo to a central one in order to, in the next time, git knows where to push and pull from.
