Resources and Converters in KSP: How they work?

[Reusables]

I want to have some intermediate resources and resources converters in my mod, but I can't figure out how it works with API documentation.

So I have couple of questions to understand how they behave and how to use them. Helpful answers would be greatly appreciated!

• How are resources declared? Is there an instance of a resource type which I can access?
• How the check for crossfeed work? Can I customize restriction of resource movement through parts?
• Can I hide a resource from UI?
• Does it support discrete amount of resource? (Or is it already discrete?)
• How does conversion work? I can't understand the interface, some explanation would be great!
• How to check for conditions in converter, and select certain conversion?
