Hi @chlawrence31 thanks for your contribution.
Actually github provides some standards for this purpose.
So filename shoud be like -
CONTRIBUTING.md (root dir)
CODE_OF_CONDUCT.md (.github dir)
// We are not maintaining any docs so we can skip that.

In CONTRIBUTING.md file you also need to write basic instructions like

• setting up the project (including fork)
• Steps to build the project (Platform specific)
• Submitting the Code or raising issue
