 This FreeCAD mod adds a search bar for tools, document objects and preferences.
 
+⚠️ Several issues related to the C++ memory management interacting badly with Python's have caused lots of segfaults during development. ⚠️
+
+⚠️️ Most of these should now be solved, but save your work often and proceed with caution while testing this extension. ⚠️
+
+Extensibility
+-------------
+
 It can be extended by other mods, by adding a new result provider.
 
+Usage
+-----
+
+The search bar appars next to the What's this? tool, in FreeCAD's default File toolbar.
+
 ![Screenshot of the search bar, with results in its drop-down menu and extra info about the result in a separate pane](screenshot.png)
 
+Development
+-----------
+
+* `InitGui.py` adds an instance of `SearchBoxLight` to the GUI.
+* `SearchBoxLight` is a hollowed-out implementation of a search box, it loads everything lazily.
