The Java "securing build time" page is incomplete.

[JoeBeeContrast]

The Java documentation is incomplete. I strongly doubt anyone outside of contrast would be able to use this to successfully run the CLI tool on a Java build.

There are two commands listed.
npm install -g @contrast/contrast-cli
which installs the cli
and
contrast-cli --yamlPath scan.yaml
Which does, nothing...
Before this there is no reference to a scan.yaml file, or what it should contain.

This page should contain step by step instructions on how you setup the cli to generate a scan/sbom. With the only thing you need is to drop in your api key/auth token. And there should be instructions on how you get those.
Also example Java application, such as https://github.com/Contrast-Security-OSS/vulnerable-spring-boot-application with an example of the build integration would also be very useful. With examples for gradle and maven.

Same for the Node version of this page
https://developer.contrastsecurity.com/learn/guides/devsec-with-contrast/tutorial-node/securing-build-time/
It's a copy/pasta of the Java one. It even includes references to pom.xml/gradle.
