I think we generally prefer markdown tables to HTML tables, mind converting them?

I started with Markdown tables, but it didn't display correctly for me and I noticed other pages used the html tables, so I actually converted them to HTML.

Are you sure Markdown tables are supported?

@Xephyz I am probably misremembering then. @nmoskaleva is the docs master

@mickhansen The last table I added was in the CIBA docs, and it's HTML. So HTML is definitely the standard :)

Looks great! A few comments.

Looks great!

Looks like the "Products and their supported scopes" is missing a title for the right-most column. Probably should be something like "Supported scopes".
Otherwise, looks good!

@Xephyz remember to autosquash, this repo does not have a CI check against it.
