this explains how you have to use it
Yes I already look in wiki.
Using code below, the output will show development. At first boot, the top left show something "community devel build followi by date and other number. (git checkout 9.0.0)
In LE8.x, if I do get "git checkout 8.2.5", the code to run will be ROJECT=RPi2 ARCH=arm make image since it's a final stable version.
The output in TV, will show 8.2.5 version instead of develp.
Hope I made sense. Thanks
