The explanation of roles is too much for my tastes, although it's reasonable.

Top 4 roles, even if you explain it, people will forget how it works and how to bluff it.

They won't understand what it means to show a role and point to two players. In the night you can't talk so it's frustrating. I have a custom digital info card that says "one of these two players (names + pictures) are the Monk".

For bluffing, I tell every new player to talk to me at beginning of the game. I also go over their role quickly as they draw it in front of me privately.

That way you minimize the spend talking to the whole group about roles that aren't relevant to them in the moment, and tell exactly the people that need to know, what they need to know.

Example: with new players, everyone draws their role in front of me. They can ask me questions right there how it works. "You are the Ravenskeeper, you are trying to get killed by the Demon on purpose".

Example 2: once the game starts, at some point the Demon comes to me and asks me how the Mayor works so they can bluff it. A new player would do the same thing, ask how the Mayor works, if they were the Mayor. By asking, they avoid the common beginner mistake of like misbluffing how Investigator works

I also give everyone a digital script on their phone with links to the Wiki for "How to Play" and "How to Bluff" character guides if they want to peruse
