Ionic Analyzer with gulpfile.js

Hi, I’m reading an instruction here :

I’ve follow all the steps,
And when i run this command :
make Android

it return this :
'make' is not recognized as an internal or external command, operable program or batch file.

I think I misunderstood where to put the ‘Makefile’ file.
it said in the root folder, it suppose to be the same level as the gulpfile.js right ?

but again, its just my guess, any idea ?
