Git intro:

1. Create an account on https://github.com/ (if you don't have one).
   • Add the public key from your computer at account settings/ssh keys (for ssh login)
   • Configure your username, email and colors

     git config --global user.email "me@here.com"
     git config --global user.name "John Doe"
     git config --global color.branch auto
     git config --global color.status auto
     git config --global color.diff auto

   • Clone this repo: git clone git@github.com:iriina/GitDemo.git
2. Try some git commands:
   • Create a new file, add it to index, commit it and push it in the repo.
   • After each command call git status and look at the changes.
   • Generate a conflict with one of your colleague and solve it using the stash method:
     • Both modify the same file at the same place.
     • One of you commit and push the changes.
     • The other one follow the steps below:
       • Add your modifications to index git add; git status
       • Stash your changes in order to retrieve possible conflicting updates git stash; git status
       • Get the updates from the server git pull and manually solve any possible merge conflicts.
       • Commit the final results and push them to the server.

The following steps will guide you through the process of making a patch for the Linux Kernel.
