=> Spoof all MAC adresses - the description sentence should be
simplified. You can't explain "spoof" by "spoof" i think. My idea would
be something like:
* "Conceal the hardware identifier of your network card"
* "Conceal the unique hardware identifier of your network card"
* "Conceal the identifiable hardware identifier of your network card"
=> "Persistent volume lets you save data and configuration." I'd write:
Persistent volume lets you save data and configuration files.
