+# Panelization GUI
+
+The panelization feature of KiKit is also available via GUI in the KiCAD's PCB
+editor (Pcbnew). The main use-case for the GUI is to quickly construct the
+desired KiKit command and fine-tune the panel. It also serves as a quick help in
+case you are not sure about parameter naming.
+
+The GUI is designed to be run in a standalone instance of Pcbnew (not executed
+from a project) as the generated panel replaces the currently open board.
+
+You can invoke the GUI via clicking on the panelization icon:
+
+![Pcbnew toolbar with the icon](resources/panelizeToolbar.png)
+
+Then the following window will open:
+
+![Panelization plugin Window](resources/panelizeWindow.png)
+
+There are three parts of the window:
+
+- the left column where you can edit individual parameter sections. These
+  sections are in 1:1 correspondence to the panelization CLI. For the help on
+  their meaning please refer to [CLI documentation](panelizeCli.md)
+- the right column with:
+    - the constructed KiKit command (that you can put into your Makefile)
+    - the constructed JSON preset that you can save and later use.
+
+Note that both, the command and JSON preset, does not include a parameter if it
+is the same with the default, built-in, preset.
+
+Once you are happy with the parameters, you can click the "Panelize" button and
+the panel will appear in the Pcbnew work area. You can then edit the parameters
+and regenerate the panel.
