If during the program you have questions about Plutus, we invite you to share them at [Cardano Stack Exchange (CSE)](https://cardano.stackexchange.com/) by adding the `plutus-pioneer-program` tag to your question. The IOG's Education Team members will monitor these questions to support your learning journey. Whenever you share a question at CSE, you're helping to build up the Cardano and Plutus development knowledge base. *** This work is licensed under a [Creative Commons Attribution 4.0 International License](http://creativecommons.org/licenses/by/4.0/).
