+  <br><br>
+ In this workshop we’ll be building a GitHub bot that will greet contributors to your project. The bot will be built as a GitHub App which can then be installed to your GitHub repositories.
+We will be building a GitHub bot that can say thanks to the maintainer who installed your bot using gidgethub and aiohttp libraries. 
+If time permits, I'll also share how you can automate other parts of your workflow with Zapier.
