You're talking about a magic scroll, Equinox... different thing.
In 5e, a Spell Scroll can only be cast and used by someone who has the spell it holds on their spell list (they don't need to know the spell personally, just have it on their spell list). To anyone else, the scroll is incomprehensible and unusable.
Magic Scrolls are a different thing, and they are specifically designed to be cast and used by laypeople - they rarely contain actual spells, however, and usually hold specific enchantments or individual tailored magical effects.
In this case, we're talking specifically about Spell Scrolls.
