 If that doesn't work you can [read more about installing node on arm v6 architecture](https://www.thepolyglotdeveloper.com/2018/03/install-nodejs-raspberry-pi-zero-w-nodesource/). Also [the builds are here](https://unofficial-builds.nodejs.org/).

-I can't remember how I got ssb-server to work, `sudo npm install -g ssb-server` throws `illegal instruction`. Something to do with a woknky version of Node.

 As long as the EBB repo is at `/home/pi/ebb` the following service files should be configured fine. Otherwise you gotta edit ssb.service and ebb-carousel.service and update the `WorkingDirectory` field.
