 Once you've become comfortable with the Adobe I/O infrastructure, analyze  your current extensions and begin mapping its in-process features into the App Builder and Adobe I/O environment. Key areas to consider include:
 
-*  Service contracts
+*  APIs
 *  Plugins and observers
 *  Backend development
 *  Custom cron jobs
 *  Database data
 *  Filesystem
 
-## APIs
+### APIs
 
 [API Mesh for Adobe Developer App Builder](https://developer.adobe.com/graphql-mesh-gateway/) enables developers to integrate private and third-party APIs and other software interfaces with Adobe Commerce and other Adobe products using Adobe I/O.
