+Pileup track
+------------
+
+The **higlass-python** package also provides a way to include custom tracks in
+your view configuration. These tracks are defined in a separate (JavaScript)
+package, and can be included in Python in with some additional setup.
+
+The ``PluginTrack`` provides a mechanism to hook into the schema validation
+as well as provide the plugin source for the renderer. The ``plugin_url`` is a
+special field which points to the JavaScript source code.
+
+A plugin can be created by subclassing ``hg.PluginTrack`` and specifying the ``type``
+and ``plugin_url``. For example,
+
+.. code-block:: python
+
+    from typing import Literal, ClassVar
+    import higlass as hg
+
+    class PileupTrack(hg.PluginTrack):
