+DFHack tools
+============
+
+DFHack has **a lot** of tools. This page attempts to make it clearer what they
+are, how they work, and how to find the ones you want.
+
+.. contents:: Contents
+  :local:
+
+What tools are and how they work
+--------------------------------
+
+DFHack is a Dwarf Fortress memory access and modification framework, so DFHack
+tools normally access Dwarf Fortress internals and make some specific changes.
+
+Some tools just make a targeted change when you run them, like `unforbid`, which
+scans through all your items and removes the ``forbidden`` flag from each of
+them.
+
+Some tools need to be enabled, and then they run in the background and make
+changes to the game on your behalf, like `autobutcher`, which monitors your
+livestock population and automatically marks excess animals for butchering.
+
+And some tools just exist to give you information that is otherwise hard to
+come by, like `gui/petitions`, which shows you the active petitions for
+guildhalls and temples that you have agreed to.
+
+Finding the tool you need
+-------------------------
+
+DFHack tools are tagged with categories to make them easier to find. Note that a
+tool can belong to more than one category. If you'd like to see the full list of
+tools in one flat list, please refer to the `index <genindex>`.
