+## This repo is currently a work in progress 
+- The README.md will be fully updated once the repo is in a stable state

+# TODO:
+- Need to automate rust project (xbnet)
+    - Configure (looks good)
+    - Build
+    - Deploy
+        - On ubuntu for testing
+        - On Linux for Tegra for TX2
+        - On Jetson Orin
+- Working on setup_host_device.sh
+    - Issues with bridging interfaces
+- Need to add setup_end_device.sh
+- Need dokcerize service
+- Possibly may need to bridge docker xbnet network will local wifi interface as well
