Reference documentation for daml.yaml file

Is there a good reference for what stuff I can put into a daml.yaml file?

The main reference for the daml.yaml format is here:

https://docs.daml.com/tools/assistant.html#project-config-file-daml-yaml

This page is not fully exhaustive, and daml.yaml settings for specific tasks are located in other sections of the Daml documentation. For instance, daml.yaml settings for code generation can be found here:

https://docs.daml.com/tools/codegen.html#project-file-configuration-java-and-scala

The format is also extensible, in that each tool only reads what it cares about, and ignores the rest.

The only mandatory field is sdk-version.
