Fork this repository into your own GitHub account.

Clone that forked version to your local machine. Check that the README.md file looks like this file.

Create a new branch to work in. Call it add-my-details.

git checkout -b add-my-details

(notice the -b flag. It's important. Why?)

Edit the file about.me, replacing my name and ID with yours.

Have a look at the differences between your working copy of the file and the one you started with:

git diff

Commit the changes to your local repository

git add about.me
git commit -m 'added my details'

Go back to the master branch.

git checkout master

Have a look at about.me. Your changes are gone!

Go back to the branch you did the work in

git checkout add-my-details

Have a look at the file now. You should see the changes you made.

Push the file to your github account:

 git push -u origin add-my-details

The first time you push from a branch, you have to tell git where to put it on the destination repository. origin is the default name for a repository you clone, so this is saying "store it back in the original remote repository in the add-my-defaults branch.

Visit your project on GitHub. Switch to the "add-my-details" branch and generate a pull request. Make sure to include your name and SMU ID in the notes.
