Contribution Guide

[ktalebian]

Hello, I was going to open a PR for both phin and centra and add a few improvements:

• Replace forEach with for-loop for performance reasons
• Remove unnecessary else
• Use of const over let
• Migrate to use TypeScript

Is there a contribution guide or should I just open a PR and put it up for review? Also, I've noticed the codebase does not use any linter. Any interest in adding one?

Thanks for the suggestions. Sure, adding a linter could be helpful. I'm not really able to experiment with that too much right now, so a PR would be very much appreciated.
