 ## Limitations
 
-- Currently the debugger doesn't automatically re-attach to the local gateway
-  after you have made changes. Click on the green triangle to re-attach the
-  debugger in VS Code.
 - We only support stepping through your own module code. System code provided by
   Zuplo are minified and stripped of source maps, so you won't be able to step
   through them.
