  • Have to follow code format & style from Apache Geode [1] guidelines.
  • Should contain a README.md file with step-by-step instruction on how to set up and run the example. Diagrams give you extra credit.
  • Donations need to be licensed through ASL 2.0 and contributors need to file an ICLA[3].
