I think this is the way we should communicate, when presented with the question on how to get on Mastodon:
Copy paste from the link:
How do I use Mastodon?
Download the Mastodon app from the Apple app store or Play store.
Create an account (just like Twitter or any other social media)
Follow people, and get posting.
Why do tech journalists say it’s too confusing to catch on?
I have no fucking idea.
EDIT for clarification, don’t take this too seriously:
This “guide” is a bit of a joke made out of frustration. If you actually want to know more, including why I feel it has potential to free us from the dystopian hellscape that is modern social media, here is the “real” guide to Mastodon. It still uses simple language (and has lots of pictures!):

Most of those are all really simple, common things that are done when creating accounts on any service though. If Mastodon is literally the first service you’ve ever signed up for in your life maybe that’s justified but most people have made an account somewhere before.
And that’s the point OP is trying to make. It’s a very familiar process, except for step 1, which you can literally just ignore and pick the big highlighted blue button and avoid that scary and confusing “Pick another server” button if you’re not up to it.
