git clone git@github.com:NetworkGradeLinux/meta-mion-bsp.git

Warning

The above steps require you have a GitHub account and uploaded public key to your account. You'll also have to activate ssh-agent as the build script will fetch software from Git using SSH transport.

Tip

title	Tip

Even if the build process can be long depending on your build host, build duration can reach 30 minutes with a 32 cores machines. Subsequent builds will take significantly less time as a cache mechanism will avoid to to redo the whole build process.

Believe me, you are done !

Just wait the end of the build process and grab the freshly baked image.
