+* Update your git remote URL:
+  ```bash
+  # Check current remote
+  git remote get-url origin
+
+  # Update SSH remote
+  git remote set-url origin git@github.com:OpenHands/OpenHands.git
+
+  # Or update HTTPS remote
+  git remote set-url origin https://github.com/OpenHands/OpenHands.git
+  ```
+* Update Docker image references from `ghcr.io/all-hands-ai/` to `ghcr.io/openhands/`

+  ```bash
+  git grep -i "all-hands-ai"
