The user manual is there : http://downloads.arturia.com/products/minilab-mkII/manual/MiniLabmkII_Manual_1_0_7_EN.pdf
To use it in your DAW, make sure Analog Lab is closed before launching your DAW so the USB-MIDI port is released.
Then, in your DAW, select the Minilab’s USB-MIDI ports as MIDI input and output and use the usual workflow to route them to your plugins.
Analog Lab itself can be run as a plugin and you should appear as such.
Hope this helps.
