Just run:
sudo ./install
Flotilla Daemon will install and autostart by default.
You'll find "Flotilla Rockpool" in the Pi menu under "Programming". It'll fire up your web-browser with the Rockpool flow interface.
If you want to use the Python API you'll first have to stop Flotilla glomming onto all the available Docks. You can do this by stopping the service like so:
sudo service flotillad stop
If you want to start it up again, just type:
sudo service flotillad start
