+To build (and run locally) the SqueakPhone image, ensure your Unix user is in the `input`
+group. Follow the instructions in the [SqueakPhone
+README](https://git.syndicate-lang.org/tonyg/squeak-phone); namely, first [install
+squeaker](https://github.com/tonyg/squeaker), check out the [squeak-phone
+repository](https://git.syndicate-lang.org/tonyg/squeak-phone), and run `make images/current`
+inside it.
 
+Then, on the device, create a file `/home/user/dpi.override` containing just `256`. On the host
+machine, send your image to the device with `./push-image-to-phone.sh pm-qemu`. It should
+automatically start.
