One of the biggest things we need to get done before release is a full, proper guide for creating your own spells.

The guide will probably be primarily a "Hello World" of a Spell, getting you through setting up your environment and building the plugin to creating your first functional spell.

If you can write the tech aspects, I can make it user-friendly and nice-sounding.

Sounds good

we have a basic guide now, but I'm not going to close this issue, because I want to make a more detailed guide designed for beginners with screenshots etc.
