I am following the tutorial: "Build a real-time chat app with Node-RED in 5 minutes" http://www.ibm.com/developerworks/cloud/library/cl-rtchat-app/
But the Deploy button is not enabled. So I can not deploy.
I have installed CF command line and run "push" for my app. This is what I learned in the "Start Coding" in the dashboard, under the "CFApp". It was successful.
Is this "push" the same as the "deploy" in the Node-Red editor?
Thanks.

The deploy button is different from the CF push. The node-red deploy button is available in the node-red graphical UI.
Once you create your node-red application you have to launch it.
This is bullet number 3 on step 1 on the tutorial. On the Bluemix dashboard click in the application name to launch it.
The main window for node-red application is displayed (bullet number 4 on step 1 for the tutorial).
Clicking on the big red button "Go to your node-RED flow editor" will open the node-red flow editor (displayed on bullet number 5 on step 1). At this time you should see an empty sheet and the "Deploy" button at the top-right corner should be disabled.
Follow step 2 instructions to import the node-red flow (I included it below for your convenience):

Follow the other steps to import the flow above, deploy and run the application.
