How do I debug my meteor app? Node-Inspector instructions are out of date.

[taji]

I was confused by the answer here:

1. Install node-inspector: npm install -g node-inspector
2. Start meteor: NODE_OPTIONS='--debug-brk' mrt run
3. Start node-inspector
4. In Chrome, go to the URL given by node-inspector
5. If debugging remotely, make sure the port given at the URL above (8080) is not firewalled
6. Debug at will

Isn't this relatively obsolete based on the meteor debug command? I'm assuming that meteor is packaging node-inspector into meteor as they do with node and mongodb. So why advise the reader to install a version of node-inspector that may not be compatible?
