Publish

Once the snap is built, you’ll have a <name>.snap file
in your root project directory. You can now publish the snap.
The process consists of the following:

Create a developer account at snapcraft.io, if you
haven’t already done so.

Register the app’s name. Registration can be done
either using the Snap Store Web UI portal, or from the
command line, as follows:
    
$ snapcraft login
$ snapcraft register

Release the app. After reading the next section
to learn about selecting a Snap Store channel,
push the snap to the store:
    
$ snapcraft upload --release=<channel> <file>.snap

Snap Store channels

The Snap Store uses channels to differentiate among
different versions of snaps.
