 Standard Configuration Sets
 ---------------------------
 
+The following sections explain some core commands added by well-known configuration sets.
+
+If you want other setups (`rtinst`, `QuickBox`, …) to be documented, we accept pull requests.

 `rTorrent` Wiki Template
 ^^^^^^^^^^^^^^^^^^^^^^^^
 
 The `CONFIG Template`_ wiki page defines a few commands in its configuration snippet.

+    cfg.basedir
+    cfg.watch
+    cfg.logs
 
+        These define important base paths in the file system layout of a `rTorrent` instance,
+        and are all private. They are used where appropriate to define further paths
+        like the session directory, and allow easy changes at just one place.
 
-`pyrocore` Configuration
-^^^^^^^^^^^^^^^^^^^^^^^^
+        By default, ``cfg.watch`` and ``cfg.logs`` are sub-dirs of ``cfg.basedir``.

+    pyro.extended
+
+        Set ``pyro.extended`` to ``1`` to activate `rTorrent-PS` features.
+        Note that this *tells* the rest of the configuration that it can
+        safely use the extended command set – it *won't* magically make a
+        vanilla `rTorrent` an extended one.
+
+        Starting with `rTorrent-PS 1.1+`, this setting is detected automatically,
+        thanks to :term:`system.has`.
+
+    pyro.bin_dir
+
+        A constant that should be set to the ``bin`` directory
+        where you installed the `pyrocore` tools.
+
+        Make sure you end it with a ``/``;
+        if this is left empty, then the shell's path is searched.
