+# Kernels CLI Reference
+
+## Main Functions
+
+### kernels upload
+
+Use `kernels upload <dir_containing_build> --repo_id="hub-username/kernel"` to upload
+your kernel builds to the Hub. 
+
+**Notes**:
+
+* This will take care of creating a repository on the Hub with the `repo_id` provided. 
+* If a repo with the `repo_id` already exists and if it contains a `build` with the build variant
+being uploaded, it will attempt to delete the files existing under it.
+* Make sure to be authenticated (run `hf auth login` if not) to be able to perform uploads to the Hub.
