Eric Anderson, a fellow Earthling, will be talking about how to get the Sage starter theme up and running and some general conventions for creating custom WordPress themes. Sage has a few automated build processes and he’ll spend some time going through how to get that set up as well. Please come with questions about custom themes even if they aren’t related to Sage!
Note: Sage 9 has just been released but he will be talking about Sage 8 since he hasn’t had enough time to work with Sage 9 to talk about it competently. If you want to start checking out Sage 8, here a link to the latest Sage 8 release: https://github.com/roots/sage/tree/8.5.4
