Like many, I am marvelling at the nautical goodness that Pimoroni has recently shipped across the seven seas. Tinker Bell may even have put some pixel dust in your stockings...
So... you're on the starting block but mildly confident what to plug where and when to click what? The good news is that Flotilla is extremely intuitive to use but like any new songs reading the words to it helps you get intimate with the music...
I've therefore assembled a Getting Started guide for Flotilla and Rockpool in particular that I hope will get you comfy with your new tentacled friend. Without further ado:
