Stylistic choice or not, the lack of literally any capital letters doesn't lend itself kindly towards dyslexic or non-native-english-speaker's comprehension.
Furthermore, with no screenshots or images to speak of in the PDF, it feels like it'd work just as well as a plain text document. If you're going to make it be a PDF, at the very least include example images or something of the like.
That, or simply create an additional, optional plaintext document accompaniment with proper grammar and capitalization for people who value comprehension above atmospheric flavour.
Also, it'd be nice if there was an additional exact step-by-step rundown of Discord permissions to grant each role.
As-is, the Discord Template Link provided doesn't appear to offer anything in terms of roles; instead only gives a bunch of channels.
(Unless the implication is that both investigators and ghosts should be able to talk in every channel, as well as create channels on the fly, in which case... I guess the entire game relies on people not messing up and forgetting what they're doing? Doesn't feel like it's taking full-advantage of Discord's capabilities.)
For anyone who's running this game, I personally recommend you set up various roles (e.g. the Investigators don't get permission to type in any of the house's text-channels, the Ghosts don't get permission to speak in the walkie-talkie voice-channel, as well as the Ghost role has the ability to create new channels in the house-categories, etc.) This will eliminate any potential confusion as to who is what, as well as make sure players don't accidentally overstep their roles.
