Enable ssh https://linuxize.com/post/how-to-enable-ssh-on-raspberry-pi/ 
  To enable SSH on your Raspberry Pi perform the following steps:
  Power off your Raspberry Pi and remove the SD card.
  Insert the SD card into your computer’s card reader. The SD card will mount automatically.
  Navigate to the SD card boot directory using your OS file manager. Linux and macOS users can also do this from the command line.
  Create a new empty file named ssh, without any extension, inside the boot directory.
  Remove the SD card from your computer and put it in your Raspberry Pi.
  Power on your Pi board. On boot Pi will check whether this file exists and if it does, SSH will be enabled and the file is removed.
