Where is layout usage documented?

[leducvin]

Hi, I'm trying to use this amazing package for the first time. So far I'm only using the default theme with the default layouts included in slidev.

However, I'm having difficulty using the layouts properly, mainly because I don't know what fields they accept in the front matter blocks.

Of course, some of it is documented at https://sli.dev/builtin/layouts.html. Maybe I missed something, but I find this page is lacking many parameters for many layouts.

For example, some layouts use image, others media or even background to specify an image file. Another example are the iframe layouts, for which I had to guess (and search github issues) that the scale parameter exists and can be used to change the effective zoom of the iframe. It accepts a float 0-1, apparently.

Is the best place to see layout usage the source code? If so, where?
