Is your feature request related to a problem? Please describe.
Not a problem.

I am attempting to help with this issue, but I am a little stuck getting started. All the npm commands fail. It looks like they are maybe written to work in windows?

Describe the solution you'd like
It would be awesome to have some development instructions to work with. EG windows, node 14, etc... and the general flow of the workflow when developing.

Describe alternatives you've considered
No alternatives

Additional context
Thanks for the plugin! It's great.

First of all, thank you for willing to contribute to this project.

The development process is not as good as I wished it would be, but you are right I should at least explain how one should approach this project if he wish to contribute to it. I will try to get to it this week.
