 # Code + Learn
 
-Code + Learn is a worldwide initiative of workshop sprints to introduce new developers to working on Node.js.  Supportive, hands-on sessions are mentored by existing contributors and tackle real problems.
+Code & Learn events allow you to get started (or go further) with Node.js core contributions. Experienced contributors help guide you through your first (or second or third or fourth) commit to Node.js core. They also are available to provide impromptu guided tours through specific areas of Node.js core source code.
