Cannot figure how to install

Hey I am trying to install, I put the 2 files in the wp-content and home directories as stated.

My problem is I do not know what to configure. I tried putting in my password and database info and deleting the other 2 connection fields below that but honestly I don’t know what I’m doing.

I have a site with 4 sites combined in 1 db. I want to either get those 4 sites out into 4 databases, or if not possible, keep the 4 together and create new ones attached to a DB each.

I only want to have users connected. Such as if I make a new site for userx then userx can use my site also with his same username and password.

Currently an issue is the WP profile information spreads across all sites and it’s near impossible it seems to get an avatar pic up to all 4 sites. So I am hoping separate databases could help me solve this issue if I can separate my 4 current sites. But if not I still do want to be prepared to keep these and other site related issues at hand, but still allowing users to sign in with same username and password to all sites, just not with admin permissions to all but I think WP handles all that

Thanks for your time!
