+Installing extensions
+=====================
+
+If you want to use any Mopidy extensions, like Spotify support or Last.fm
+scrobbling, you need to install additional Mopidy extensions.
+
+You can install any Mopidy extension directly from PyPI with ``pip``. To list
+all the extensions available from PyPI, run::
+
+    pip search mopidy
+
+Note that extensions installed from PyPI will only automatically install Python
+dependencies. Please refer to the extension's documentation for information
+about any other requirements needed for the extension to work properly.
