Devhub Content Issue: at https://developer.gov.bc.ca/Design-System/About-the-Design-System, there's mention of improving documentation. Improving design documentation is my speciality! Also, I'm quite good with technical documentation and user documentation. If Design System folks need editing, I'd like to step up and volunteer :)
