+This project implements a real time platform to deploy the O-CU and O-DU and it's based on Yocto/OpenEmbedded.
+
+This includes a Yocto/OpenEmbedded compatible layer meta-stx-oran and wrapper scripts
+to pull all required Yocto/OE layers to build out the reference platform.
+
+To contribute on this project, basic knowledge of Yocto/OpenEmbedded is needed, please refer to the following docs if you want to learn about how to develop with Yocto/OpenEmbedded:
