Description

Maybe add the necessary "" to the basic instructions ....?!?!? took me like a whole 5 min to search and figure out that NOWHERE in the original docs informs of the required quotations around the desired URL.

1. Follow the template according to READ THIS BEFORE OPENING A NEW ISSUE! THIS MEANS YOU! #30839.
2. It's a FAQ answer.
3. Learn the Highway Code before you use your newly downloaded free car.

The importance, and style, of quoting depends on your shell, which we can't control.

Now that macOS is coming with zsh as default, which treats embedded ? specially, it may be worth rolling more explicit advice into the installation help.

There could be a paragraph of basic advice at the end of the Installation section including links to the FAQ.
