I haven’t seen it mentioned, but you might want to know about the cookbook: The Home Assistant Cookbook - Index. This was created by a number of people (among others) that have responded here.
As mentioned, the docs are a technical reference. The above is a how to guide.

The YAML examples can be quite inconsistent: in some cases the main key would be there and in other cases not. This can make it hard for people 5o know where to place it. Or when an option is a list or dictionary — or either. Luckily anybody can co tribute a fix or improvement.
