+From QGIS
+^^^^^^^^^
+
+DebrisFrame can be run from QGIS via the OpenNHMQGisConnector plugin. The plugin
+installs the required Python packages into QGIS's Python environment and adds
+the DebrisFrame modules in the QGIS Processing Toolbox.
+
+Install the connector from ZIP
+""""""""""""""""""""""""""""""""
+
+The connector version required for DebrisFrame is not available on
+`plugins.qgis.org <https://plugins.qgis.org>`_ yet and is distributed as a zip
+file instead.
+
+#. Get the ``OpenNHMQGisConnector.zip``.
+#. In QGIS, open ``Plugins > Manage and Install Plugins...`` and switch to the
+   ``Install from ZIP`` tab.
+#. Select the downloaded zip file and click ``Install Plugin``.
+#. Make sure the plugin is enabled in the ``Installed`` tab.
+
+Install the DebrisFrame package
+""""""""""""""""""""""""""""""""""""""""
+
+#. Open the Processing Toolbox (``Processing > Toolbox``).
+#. Expand ``OpenNHM > Admin`` and run ``Install DebrisFrame``.
+
+The tool installs the ``debrisframe`` package from PyPI. DebrisFrame requires
+AvaFrame ``>= 2.2b1``. Since ``2.2b1`` is a pre-release, pip does not install it
+by default. The tool installs AvaFrame with the ``--pre`` flag. If an
+older AvaFrame is already installed, you are asked before it is replaced.
+
+If you prefer to install AvaFrame 2.2b1 yourself, or if the installation via the
+tool fails, run::
+
+  python -m pip install --user --upgrade --pre avaframe
+
+On Windows, open the **OSGeo4W Shell** from the start menu and run the command there.
+If you have multiple QGIS versions installed, choose the OSGeo4W Shell that matches
+your QGIS version.
+
+Restart QGIS afterwards for the DebrisFrame tools to appear.
+
+Run a module
+""""""""""""
+
+After restarting QGIS, the DebrisFrame tools appear in the Processing Toolbox
+under ``DebrisFrame_Experimental``. See :ref:`workflow:Application via QGIS` for
+an overview of the available modules and how to run them.
