 The GitHub issues tracker contains a 'Good First Issue' tag. Filtering by this tag will show issues that are well suited for new contributors.
 Try to find an issue that seems like an obvious win. If your issue seems unclear or complex, and you've given it a good shot, consider asking for help on Discord or the Forum before investing too much time (see below).
 
+### Developing Addons and Workbenches
+
+If you are interested in creating addons or workbenches for FreeCAD, the [Addon Academy](https://github.com/FreeCAD/Addon-Academy) provides comprehensive guides covering the full addon lifecycle — from project creation and scaffolding with Cookiecutter, through development and testing, to publishing via the Addon Manager and long-term maintenance. It also covers important topics like licensing, dependency management, and code structuring.
+
 Please note: While existing contributors try their best to be helpful, open source projects attract many first-time contributors, many of whom may not stick around for long.
 As such, existing contributors have limited time to help all newcomers. Please don't be offended if your questions go unanswered. Your contributions are still appreciated.

+
+### [Source Documentation (SourceDoc)](https://github.com/FreeCAD/SourceDoc)
+Doxygen-generated API documentation for the FreeCAD C++ source code. This provides class hierarchies, method signatures, and detailed reference documentation for core modules.
+
+> **Note:** The SourceDoc is currently based on FreeCAD version 0.20 and may not reflect the latest API changes in the development branch. For the most up-to-date API information, consider generating the documentation locally from the source tree, or consult the [Python stubs package](./technical/PythonStubsPackage) for Python-level API reference.
+
+### [Ondsel Lens Documentation](https://github.com/FreeCAD/lens-docs)
+Documentation for [Ondsel Lens](https://lens.ondsel.com/), a free/libre product data management (PDM) system designed for FreeCAD and FreeCAD-based software. Covers the web interface for managing CAD data, version control, and collaboration features.
