I merged a Pull Request Template to be used by requesters who wish to submit projects to HT awesome list. (including a checkbox for COC at the top). Also raised this issue with list of dotted points for deciding an inclusion/update of HT awesome list. We can include some points from this to the Contributing guidelines too after your comments.
Please review : Issue #16 and let me know what you think.
We can reuse the similar PR template with modifications for other repositories also.
