1. Create a directory, move the downloaded snapcraft.yaml file into the new directory and navigate there:

   mkdir ~/ros-talker-listener-{name} && mv ~/Downloads/snapcraft.yaml ~/ros-talker-listener-{name} && cd  ~/ros-talker-listener-{name}

2. Run snapcraft:

   snapcraft

Make sure the name matches what has been used previously (i.e ros-talker-listener-{name})

Whilst we do encourage testing your snaps, it is not required for this tutorial. If you wish you can skip this section and move on to the next step.

1. Install the snap:

   sudo snap install --devmode --dangerous *.snap

2. List your installed snaps to confirm:

   snap list

3. Run the snap:

   ros-talker-listener-{name}

4. Stop it when you tire of seeing the nodes communicate:

   ctrl-c
