Create CONTRIBUTING.MD contributing guideline

[alemorm]

Hi, @alemorm I would Iike to work on this.

Hey @Yashs911, awesome! Feel free to fork this project and submit a pull request with the change.

Just remember to clone this repository as well as the hugo-notice submodule by running the following command in any directory:

git clone --recursive https://github.com/alemorm/ucsf-radiology-getting-started.git

As for the Hugo version, I have used different versions (0.72.0 and 0.75.1) so I don't think there should be a compatibility issue as long as you use anything higher than 0.72.0. Just grab a precompiled binary for whatever operating system you are using (I use 64-bit Ubuntu) on their release page.

I will open a new issue to work on a more comprehensive contributing guideline.

PR #17 was a good starting point for this issue and provided a template for CONTRIBUTING.md but it still needs to be more specific to this project. Reference the Getting Started section of the README.md at the beginning of the file (Issue #18)
