trying to spin up an instance using a raspberry pi 4

I wanted to run my own Lemmy instance but I don't have the physical space / server to run anything massive so I was trying to use a pi 4. Using the Ansible instructions I get most of the way through up to it trying to start the docker compose instance it mentions there's no Arm in the manifest file. I know it's not the strongest device but does Lemmy not support the pi outright?
