+##### Using sphinxHook {#using-sphinxhook}
+
+The `sphinxHook` is a helpful tool to build documentation and manpages
+using the popular Sphinx documentation generator.
+It is setup to automatically find common documentation source paths and
+render them using the default `html` style.
+
+```
+  outputs = [
+    "out"
+    "doc"
+  ];
+
+  nativeBuildInputs = [
+    sphinxHook
+  ];
+```
+
+The hook will automatically build and install the artifact into the
+`doc` output, if it exists. It also provides an automatic diversion
+for the artifacts of the `man` builder into the `man` target.
+
+```
+  outputs = [
+    "out"
+    "doc"
+    "man"
+  ];
+
+  # Use multiple builders
+  sphinxBuilders = [
+    "singlehtml"
+    "man"
+  ];
+```
+
+Overwrite `sphinxRoot` when the hook is unable to find your
+documentation source root.
+
+```
+  # Configure sphinxRoot for uncommon paths
+  sphinxRoot = "weird/docs/path";
+```
+
+The hook is also available to packages outside the python ecosystem by
+referencing it using `python3.pkgs.sphinxHook`.
