+Development
+-----------
+
+When developing malcontent, you should be able to run an uninstalled version of
+`malcontent-client` or `malcontent-control`, as long as the polkit files from
+`accounts-service/` and `malcontent-control/org.freedesktop.MalcontentControl.policy.in`
+have been installed system-wide (typically under `/usr/share/polkit-1`) where
+your system copy of polkitd can find them.
