Exercises

1. Fork & Clone

• Hit 'Fork' on this repo (it's in the top right!)
• Make sure you are now looking at your fork (it will say <your-github-username>/lfa-hello-github at the top of the page)
• Click the green 'Code' button and copy the SSH option if you have already setup git in your terminal, or the HTTPS option if not.
• Clone down your fork using git clone <what you copied> in your terminal
• Move into the project folder with cd lfa-hello-github

2. futureproof your fork

Okay, bad pun but it's true! Throughout the course we will be asking you to contribute to this repo again, so we want to make sure you can always get the latest version to work on

• Add us as a remote with git remote add upstream https://github.com/LaFosseAcademy/lfa-hello-github.git
• Check that all is well so far by running git remote -v - You should see something similar to the following:

origin	  https://github.com/<your-github-username>/lfa-hello-github.git (fetch)
origin	  https://github.com/<your-github-username>/lfa-hello-github.git (push)
upstream	https://github.com/LaFosseAcademy/lfa-hello-github.git (fetch)
upstream	https://github.com/LaFosseAcademy/lfa-hello-github.git (push)

3. Make a Change

⚠️ If you have left it a while since doing that fork, clone and adding the upstream remote please sync your repo to our before continuing by running:
git pull upstream main

• Open it up in a text editor (if you have setup VS Code, you can do this from the command line using code .)
• Make a change! In the students array, add a new JSON object with a key of "name" and string value of your name and another key of "github" and string value of your GitHub username to <your-cohort>/roster.json and save the file (Windows/Linux: ctrl+s / MacOS: command+s). See example below and in other cohorts' rosters.
• Check the git status of the project with git status - <your-cohort>/roster.json should show in red as there are unstaged changes

{
  "name": "Loki Laufeyson",
  "github": "VariantL1130"
}

4. Stage your Change

• Stage your change with git add . (or git add <your-cohort>/roster.json)
• Check the status again - <your-cohort>/roster.json should now show in green as the changes have been staged but not yet committed

5. Commit your Change

• Commit your change with git commit -m "add <your-name>". The -m is a flag for 'message' and you must leave a message with every commit!

6. Push your Change

• Check your git status again - there should be nothing to commit now but an indicator that your local version is one commit ahead of the origin
• As it suggests, use git push to push up your work to GitHub!

7. Make your first PR

• You made your own fork of this, in the web browser go to your repo https://github.com/<your-github-username>/lfa-hello-github to see if you can make a Pull Request back to LaFosseAcademy/lfa-hello-github. Try and request review from @rom-30 or @moniafavaro. We will merge your PR when we receive it!
