**Developer session (10AM to Noon Pacific)**

* 20 minutes on Besu and Github - source (3 repos), issues, PRs, code checkout, CI.

* 20 minutes on setting up with an IDE. Run and compile with Gradle. Checks and validations in place with spotless and errorprone.

* 20 minutes on the main repository content, describing types of tests in place, showing the tree of dependencies between Gradle modules.
