Github Classroom

All items of assessment will be given and answered using Github Classroom.
Git and Github
- Git is a free and open source distributed version control system designed to handle everything from small to very large projects. Git runs a repository on your computer.
- Github is a hosting service for software development and version control using Git. Github runs in the cloud, and stores files from your local Git repository.
- You can run Git alone, or hook it up to a Github repository.
- If you don't have Git on your computer, you should get it.
- If you don't have a Github account, you should make one and create a personal access token. Copy your token and save it somewhere safe.
- Identify yourself to Git. Use the same user name as for Github.
```
git config --global user.name "YOUR_USERNAME"
git config --global user.email "YOUR_EMAIL"
```
- Tell your local Git to use your access token. You will have to provide it when you first "push" (see below)
```
git config --global credential.helper store
```
  Git stores it as plain text in ~/.git-credentials.
Each item of assessment will have a link to Github classroom.
- Click the assessment link.
- "Accept this assignment"
- Wait 30 seconds before you click the link to the repository that has been created for you.
- Get the repository URL from the green <> Code menu. Use the HTTPS option (the default) and copy the link.
- On your computer do git clone paste_the_URL_here.
- Change into the repository directory to do your work.
- Add your answer files to the staging area
```
git add MyFile.txt MyCode.py etc. 
```
- Commit the files
```
git commit -m "SOME USEFUL MESSAGE" 
```
- Commit whenever you want after making changes. To avoid having to do a "git add" each time, use
```
git commit -a -m "SOME USEFUL MESSAGE" 
```
- Push the repository to Github. This first time you have to provide your Github login, and your access token as the password.
```
git push -u origin master 
```
  master could also be main, depending on your version of Git.
- At stable points after some commits push again (note you just "push")
```
git push 
```
- You can view the commmited code in Github.
