Confused about installing Option #1: multiple sites with multiple databases - from one /wire code base

[modifiedcontent]

I have trouble following the instructions here. 

I have several virtual domains successfully installed on Apache Ubuntu, with index.php placeholder files. I want to install Processwire sites in each of them, each with their own config and database, and have all of them use the same /wire codebase in /domainone.

/www/html/domainone/site (+ /wire)

/www/html/domaintwo/site

/www/html/domainthree/site

etc.

The 'how to install' instructions on the link talk about creating subdirectories off the web root, tmp directories, moving and renaming folders, having to come up with different names for the site folders, etc. It does not sound like what I am looking for.

Is there a simpler way to get the structure described above? ChatGPT claimed I could just bootstrap the /wire folder into the other with one line and install normally, but that did not work of course.
