Translate a Video Game Achievement Guide From Jargon Into Clear Steps

The guide exists. It assumes you know what a missable is, what NG+ means, and why the order matters. This translates it into plain steps: prerequisites, what to do in order, anything that is permanent or time-sensitive, and the thing the guides keep leaving out. Name the game and the achievement.

You want to unlock a specific achievement or trophy but the guide assumes knowledge you do not have. Describe what you are trying to do: [game name and achievement description].

Translate the commonly available guide into: (1) what you need to have done or unlocked first; (2) the steps in plain language, in order; (3) any choices that are permanent or time-sensitive; (4) one thing the guides consistently fail to mention that trips people up.
