+## Applying License Header to New Files
+
+If you submit a contribution that adds a new file, please add the license
+header. You can do so manually or use the `ltag` tool:
+
+
+```console
+$ go get github.com/kunalkushwaha/ltag
+$ ltag -t ./license-templates
+```
+
+The above will add the appropriate licenses to Go files. New templates will
+need to be added if other kinds of files are added. Please consult the
+documentation at https://github.com/
