As a developer and an experience designer using a tool like Builder.io is amazing but there is always a learning curve for the individuals which aren't tech savvy to get into using the tool especially for the content managers especially if our clients want to act in this responsibility.
A training video / article series showing how to use the CMS as a content manager would be a great idea way to ensure our clients are empowered to look after their platform and to ensure we can onboard our internal staff as well.
