In terms of design, the site design (1) doesn't promote a linear flow of reading, (2) doesn't space out information with enough padding, (3) doesn't make good use of text sizing to create an information hierarchy, (4) has too many disparate and messy screenshots, and (5) has distracting cursor animations and alignment shifts when hovering over the top navbar. Overall, it makes for a messy, cluttered reading experience and imo likely turns many people away. Here's the page I'm talking about:

The important thing is to present a very clear "how this is used" right away, targeted at a narrow set of use cases, in an easy-to-follow, nice design. Not too many examples; one key feature at a time. For the audience of devs, they need to see how the platform is used at the most basic level (the code and UI screenshots on that Payload CMS site are good examples). If you find that Payload site's layout confusing, you're probably out of sync with modern design. In any case, I hope this feedback helps.
