 Note that a "Convex" collision body will work better for simple meshes. For more
 complex shapes, select "Create Trimesh Static Body". Once each mesh has
 a physics body and collision shape assigned, your mesh library is ready to
 be used.

+Inspector properties
+~~~~~~~~~~~~~~~~~~~~
+
+The **Physics Material** setting allows you to override the physics material for
+every mesh in the NavigationMesh.
+
+Under **Cells** the size property should be set to the size of your meshes. You can
+leave it at the default value for the demo. Set the "Center Y" property to "Off".
+
+The Collision options allow you to set the collision layer, collision mask, and
+priority for the entire grid. For more information on how those work see the
+:ref:`physics section<doc_physics_index>`__ of the docs.
+
+Under **Navigation** is the "Bake Navigation" option, if enabled it creates a
+navigation region for each cell that uses a mesh_library item with a navigation
+mesh.
+
+If you click on the MeshLibrary itself in the inspector you can adjust settings for
+individual meshes, such as their navigation mesh, navigation layers, or if the mesh
+casts shadows.

+GridMap panel
+~~~~~~~~~~~~~
+
+At the bottom of the editor is the GridMap panel, which should have opened
+automatically when you added the GridMap node.
+
+.. image:: img/gridmap_panel.webp
+
+From left to right in the toolbar:
+
+- **Transform**: Adds a gizmo to the scene that allows you to change the
+  relative position and rotation of the gridmap in the scene.
+- **Selection**: While active you can select an area in the viewport, click and drag
+  to select more than one space on the grid.
+- **Earase**: While active, click in the viewport and delete meshes.
+- **Paint**: While active, click in the viewport and add whatever mesh is currently
+  selected in the GridMap panel to the scene.
+- **Pick**: While active, clicking on a gridmap mesh in the viewport will cause
+  it to be selected in the GridMap panel.
+- **Fill**: Fill the area that has been selected in the viewport with whatever mesh
+  is selected in the GridMap bottom panel.
+- **Move**: Move whatever mesh or meshes are currently selected in the viewport.
+- **Duplicate**: Create a copy of whatever the selected mesh or meshes in the
+  GridMap are.
+- **Delete**: Similar to erase, but for the entire selected area.
+- **Cursor Rotate X**: While the paint tool is selected, this will rotate the mesh
+  that will be painted on the X axis. This will also rotate selected areas if they
+  are being moved.
+- **Cursor Rotate Y**: While the paint tool is selected, this will rotate the mesh
+  that will be painted on the Y axis. This will also rotate selected areas if they
+  are being moved.
+- **Cursor Rotate Z**: While the paint tool is selected, this will rotate the mesh
+  that will be painted on the Z axis. This will also rotate selected areas if they
+  are being moved.
+- **Change Grid Floor**: adjusts what floor is currently being worked on, can be
+  changed with the arrows or typing
+- **Filter Meshes**: used to search for a specific mesh in the bottom panel.
+- **Zoom**: controls the zoom level on meshes in the bottom panel
+- **Layout toggles**: These two buttons toggle between different layouts for meshes
+  in the bottom panel.
+- **Tools dropdown**: This button opens a dropdown menu with a few more options.
+
+.. image:: img/gridmap_dropdown.webp
+
+Clicking on **Settings** in that dropdown brings up a window that allows you to
+change the pick distance, this is the maximum distance at which tiles can be placed
+on a GridMap, relative to the camera position (in 3D units).
