+# Syncthing on a Kobo eReader
+
+This installs [Syncthing](https://syncthing.net) on a Kobo eReader.
+
+Syncthing will be installed in `/usr/local/syncthing` with a udev rule
+`99-syncthing.rules` to automatically start it on network device
+detection.
+
+## Build
+
+Run `make` to build the update tarball `KoboRoot.tgz`.
+
+## Install
+
+Place the built `KoboRoot.tgz` file in the `.kobo/` folder of your
+eReader and eject it.
+
