The current documentation for using Heat (web/src/Docusaurus/docs/tools/heat.md) does not mention the Include attribute in any of the reference sections, only in examples. Because this is actually the most important thing about the whole idea—it specifies what to harvest in the first place—I think it should be documented.

In particular (and because I am confident this will be omitted as obvious unless I mention it here) the documentation should make clear exactly what a relative path in the attribute's value is relative to. I think it must be the directory of the project file, but you never know.
