+# dogfood template
+
+Ammar is this template's admin.
+
+This template runs the `gcr.io/coder-dogfood/master/coder-dev-ubuntu` Docker
+image in a `sysbox-runc` container.
+
+## Personalization
+
+The startup script runs your `~/personalize` file if it exists.
+
+## How is this hosted?
+
+Coder dogfoods on a beefy, single Teraswitch machine. We decided to use
+a bare metal provider for best-in-class cost-to-performance. We decided to
+use a single machine for crazy fast parallelized builds and tests.
+
+## How is the provisioner configured?
+
+Our dogfood VM runs an SSH tunnel to our dogfood Docker host's docker socket.
+The socket is mounted on `/var/run/dogfood-docker.sock`.
+
+The SSH command can be found hanging out in the screen session named
+`forward`.
+
+The tunnel and corresponding SSH key is under the root user.
