+## Running `gosher` under `chroot`
+
+In general, it makes sense to run a server in a `chroot` environment, to
+reduce the risks connected with remote exploits. If you would like to
+run `gosher` under `chroot` be sure to have the following binaries (and
+the corresponding libs) available in the chroot-ed environment:
+
+```
+	basename cat cut mkfifo netcat realpath rm sed sh
+```

+Obviously, `netcat` will be your preferred `netcat` implementation.
