[jstarry]

looks good to me but I think ci is going to complain about the line length on line 513

@jstarry comment fixed :)

I'm not sure this modification is necessary. This is just a general note saying to make sure the CLI is installed, no command an earlier note already says that we'll be using the sol user so this seems repetitive

[romeo4934]

Before on this page, you wrote to create a sol user.
https://docs.solanalabs.com/operations/setup-a-validator#sol-user
I believe if you recommand to create a sol user, then installation CLI should be installed by this sol user right?
I was myself confused if I had to install the CLI with the sol user or with the root user following each instructions on this page. I had to ask someone on the discord for clarification.

Ahh I see, I was a little confused based on where you added "with the sol user" in the sentence. At the end there, it seems to be reinforcing that the validator will be run with sol user, not which user to use to install it.

Yep, and shortly after that bit we have this note

It is a best practice to always run your validator as a non-root user, like the sol user we just created.

Altho it doesn't directly say it, this comment implies that the CLI needs to be accessible to user sol

Technically it isn't required, but to keep things simplest, yes, the CLI should be installed with user sol.

Now that I understand your point of view, I'm in favor of it. However, I think it is a little ambiguous where you added the note. How about an extra (but short) sentence:
