*install evothings workbench
*install evothings client app on your mobile device
*by starting evothings client on your computer you create a "server", then just start the evothings client app on your mobile device and connect to it
*after you're connected, just click "run" on any of the demos listed in the evothings client app. what is cool that if you change any of the files in the folder opened after clicking on "code" the mobile app automatically updates. that's it!
you should, however, be present on the same local network. both your cellphone and computer
publishing app is another chapter (althought not a difficult one, just a lot of installs), perhaps you should play with evothings client at first
