Looking for 1P for Dummies

Thank you for the response. I had high hopes with 1Password University for a minute. Then I went to the site...it's a sales pitch. I need concrete How-To directions for setting up.

I'm switching between a laptop and and an iPad so that complicates things...nothing comes up on the screen in the same way twice. I clip on the icon at the top of the screen, it sometimes fills the password, sometimes is asks for the 1P password 2 or 3 times before filling the password.
I filled out my DL information on a Drivers License form. I can copy but not fill from that form. I just can't find clear directions for Dummies.
