It is something like this:

1. Create an IBM account by visiting: https://internetofthings.ibmcloud.com/ (someone should verify this url)
2. Verify email
3. Forgot password
4. Create new bluemix free. (don't recall actual step here)
5. Add device (use mac address without colons?), type must be "PAPA" (or whatever you use in PapaExample), copy/paste token into PapaExample
