I’m having a really hard time to understand even the “beginner’s method” on that wiki.

For example, it entirely glosses over how to solve the „first two layers“ (F2L) on the left and back faces. It only ever explains F2L for the front and right faces. However, I can’t possibly achieve a „yellow cross“ that way. I wonder why I can’t seem to find any source that actually explains it.

I generally prefer written tutorials over video tutorials, but cubing related stuff is an exception. Videos are easier to digest.

Here's a good beginner tutorial:

Thank you!

Thanks. Looks promising!
