The explanation you need may be about the order of the steps, not the steps themselves.

Confusion is often not about missing information. You can know every piece and still not know what has to happen before what, and that gap feels like slowness when it is really sequence. Written instructions tend to list the parts thoroughly and leave the shape of the process unsaid, because whoever wrote them stopped noticing they knew it.

When something refuses to come together, stop rereading the steps. Ask someone who has done it to tell you the order, and which points cannot be moved.
