Hi friends!

The purpose of this repo is for us to have a place where we can put instructive resources. Hopefully, this way whenever someone is starting to delve into a new challenge (Compute Canada, parallel programming, bash scripts, etc) they have many helpful documents available!

Submission instructions

• Organization:
  • If you're submitting a new tutorial or document, first check if there are any existing subdirectories where it can go. Else, create a new subdirectory!
  • Please make sure not to do git add . or something similar; we don't wan't random files like __pycache__ or .DS_store floating around.
• Author statement: Don't forget to put your name and date at the top of the document.
• Table of Contents: Once you're done, add a section to the table of contents briefly explaining your document.
• Closing issues: If your document resolves an issue, include something like "closes #10" in your pull request, which will automatically resolve the issue when it's merged.
