Help upgrading Docker 5.0.2 to 6.0.0

So I did. Here, comment 39/131.

But even so, I’m not sure what you’re suggesting I do here and now. That was an initial installation. I now need to upgrade. The upgrade instructions I posted above are not clear to me. The wording:

“set a shared volume for (such-and-such) a directory”
“do a docker-compose up”

I do not know what these phrases mean or how to carry them out.

Thank you.
