+# Notice
+The **C3 series daughterboard has been deprecated** with the launch of the [C4 series](https://github.com/Unified-Daughterboard/UDB-C).  
+This repository will be kept up for the sake of the ability to maintain legacy keyboards, but the legacy C3 daughterboard is now not-for-new-designs - **please use the newer daughterboards instead for new keyboard projects**.  
+  
+In addition, documentation has moved to the new [documentation site](https://unified-daughterboard.github.io/).
