+## Alternative development ecosystems
+
+In addition to Arduino, many of our supported boards can also be used with popular development ecosystems such as **Simplicity Studio** and **Zephyr**, allowing users to seamlessly transition between platforms as their projects evolve.
+
+Please refer to the table below for ecosystem compatibility:

+ℹ️ To use the **Arduino Nano Matter** or **Seeed Studio XIAO MG24** with **Simplicity Studio**, install the [Silicon Labs OpenOCD Support](https://marketplace.visualstudio.com/items?itemName=silabs-bozont.silabs-openocd-flasher) VS Code extension alongside the official [Simplicity Studio for VS Code](https://marketplace.visualstudio.com/items?itemName=SiLabs.siliconLabsSupportExtension) extension.
+Together these extensions enable flashing and debugging of OpenOCD-based boards directly from Simplicity Studio projects.
