This looks reasonable :) Thank you. Could you also update the documentation about this in CONTENT.md?

I've done if for this PR, but please check that your editor applies our .editorconfig file when editing this repository; particularly you are missing some newlines at the end. See https://gist.github.com/olivertappin/19a95236d8b69f1c9eadfc799a9ab7fc for more info about newlines at the end of files.
