The website provides a wealth of support documentation and video on the use of the H5P tool including Getting Started, Installation & Setup, Developer Guide, Content Guide and Contributing.
Navigating the H5P OER Hub should be very easy for users. Currently the site has video demonstrations for Browsing, Sharing, and Adding Meta Data.
A note on Accessibility
The goal for the accessible content types is WCAG 2.1 AA support, so the content types have been tested against these criteria and more. The content types have gone through a lot of testing with various screen readers, keyboard navigation, zooming, code inspection and more. We can't, however, guarantee any level of accessibility support.
If you have basic skills for making a Power Point Presentation, it is easy to apply the changes proposed to add to the interactivity of your work.
