Prerequisites

You must have git installed. You can use a GUI tool like GitHub Desktop or SourceTree. I recommend learning the command-line myself, especially those wanting to do professional web development. If you want to learn the command-line version, feel free to hit me up on slack on the #git channel.

You must have node and npm installed on your machine. You can install node directly from here, but let me know if you want to know how to better manage your node installation by sending me a message on the #node slack channel.

Once that's done, you'll want to fork this repo to your own. In the top right of this page, there should be a Fork button. Do that and fork it to your personal account. This is where you will do most of your development work.

Once you have it forked to your account, clone the repo to your computer. If you're using the GitHub Deskop client, you should be able to navigate the menus to clone your newly created repo to your computer. If you want to do it the command-line way, in your forked version of the repo, copy the repo url from the right hand side of the page. Then in your terminal, navigate to your projects folder, and type git clone https://github.com/{your username here}/quiz1.git then cd quiz1.

Whether or not you opened the terminal before, now you need to and navigate to the project directory. On a Mac, you can do this by opening up the terminal and opening up the finder to the location of your project. In the terminal, type cd (that's a space after the cd) and drag your quiz1 folder from the finder window into your terminal window. It will auto-complete the path to your directory. Now press enter.

Next, type npm test to run the tests. At this point, all of them will fail and will spit nasty errors at you. You just need to open up the files in the problems directory and add the code necessary to make the tests pass!

You can run npm test as many times as you want, and it will give you the results of the tests. Keep fixing your code to make the functions do what they're supposed to.

Once your done and you have all your tests running and passing, you'll want to commit your code. In the command-line, enter git add . to stage all of your changes and git commit -m 'I fixed the tests' to commit those staged changes. After your done, run git push to push to your repository.

After you've got your code pushed up, you need to submit a pull request. On the quiz1 repo page under your account, Click on the Pull Requests button in the right sidebar. Click on Create Pull Request and make sure that dgm-ria-fall-2015/quiz1 repo is selected as the base, and yours as the compare fork. You should see a list of code differences.

Once the Pull Request is created, I'll review them as needed. Note that these are open and can be viewed by anyone. I'm not going to stop you from viewing and using others' code, but you'll be doing yourself a great disservice if you don't stop to figure out why things work the way they do. You'll be seeing and using other people's code every day, but you need to know what parts are good and what parts are garbage, or how to fix other people's code. Asking why people did things the way they did is a great way to collaborate and learn new ways of doing things.
