How to install Xbmc/Kodi to a USB flash drive(DIY) -video

Do you have to put this app in a usb and then download kodi, install it and configure it?
I`ve seen that video but is too short without any detailed instructions.
Please help if you can.
thanks.
 
I tried it. After you download installs on usb. By his instructions search for xbmc(it`s 14.0), install and configure.
You have to use a usb3.0 though.
After the trial version is over, format usb, re-install everything and use a backup of your existing setup.
