Is there a German howto/documentation for snapcraft?

[David Planella]

Hi Ralf,

In addition to the replies you've already gotten here, we're running a
weekly event called the snappy playpen, where snap pioneers help each other
getting their apps snapped.

It's on today all day (across European and some US timezones), you'll be
most welcome to join us!

You'll find out more here:

Cheers,
David.
