Is there a detailed guide anywhere about how to embed Squirrel into a project?
All I could find is the official documentation which unfortunately is very difficult to understand.
Thank you.
You have the official plugin (https://bitbucket.org/stormeus/0.4-squirrel/get/newapi.zip) at your disposal. If not, there's also this (https://github.com/iSLC/VCMP-SqMod) plugin. And then there are all the released modules/plugins in the plugins section. There's plenty of information to learn from. There's also the source code (https://github.com/albertodemichelis/squirrel). But don't expect to become some expert on it any time soon.

If you can't get started with all those examples then I'd suggest to stay away from it.
