index.theme standard doc

[Kiran Chauhan <kiranchauhan68 gmail com>]

Hi!

I am creating one theme while writing a tutorial on it and found index.theme file. I have looked around but not able to find standard docs on index.them such as we have for -

Icon Theme - https://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html

Desktop Entry - https://standards.freedesktop.org/desktop-entry-spec/latest/

Thank You,
Kiran Chauhan
