Need feedback on new Guide for Unity SDK

I've just completed the first draft on a guide for our Unity SDK for game developers. I'd appreciate any advice/opinions on some of the suggestions I've made in the guide.

For example, I've suggested `GetComponent<...>()` as a way to retrieve a reference to a `GameObject` from another script. There's a lot of confusion online about what the best approach is to sharing objects between scripts and I don't want to spread more bad information. What is the best way to handle this scenario?

Let me know what you think and what needs more work. Thanks.
