 # Pixiecore
 
 This project is a permanent fork of: [Pixiecore](https://github.com/danderson/netboot/tree/master/pixiecore)
+
+Sample command to run `pixie` in grpc mode which talks to the metal-api and provides grpc client certificates and the metal-api-view-hmac to the metal-hammer.
+With this metal-hammer will be able to talk to metal-api directly.
+
+```bash
+docker run -it --rm -name pixiecore \
+    --network host \
+    --dns 10.1.253.13 \
