Raspbian stretch and flotilla

Hi,
I have a fresh Stretch install updated / upgraded on an Raspberry pi Zero W.
I have the Mega Treasure Chest Starter Kit ordered few months ago.
So I followed the instructions :
here http://learn.flotil.la/getting-started/installation

And did the improvement found in this topic

sudo apt install libboost-system1.58 libboost-filesystem1.58 libboost-program-options1.58
git clone https://github.com/pimoroni/flotilla-offline
sudo cp flotilla-offline/flotilla-stretch /usr/bin/flotilla

But i keep on getting the message “searching for docks no docks found, yet! =(” on rockpool

Is flotilla compatible with Raspberry Pi Zero W ?
Thank you
