Git: Common usage scenario

1. Checking out remote changes:
   git clone (very first time) or git pull (always afterward)
2. Editing a file:
   E.g.: add a new function attack() to the player.js file
3. Adding a file to "staging area" for the next commit:
   git add player.js
4. Commit the modification to the local repository:
   git commit -m "Add player attack"
5. Send local modifications to the remote repository:
   git push
6. Resolution of any conflicts:
   File modification and commiting again (starting from step 3)

Note! If you start a project from scratch you do git init to create a new repository
