Customize Logon page "Find User" 5.13.1

Hello,

I need to customize the logon page for the new SelfService site. I had the update in the previous version PMUser. Then PMUser site used the user.xml located here...
C:\Program Files\One Identity\Password Manager\Web\User\App_Data\LocalizationStorage\en-US 

I had that customized but now moving to 5.13.1 and need to make the same updates there. I have some instructions for my employees posted there.
I got the previous instructions from...

www.oneidentity.com/.../modifying-self-service-home-page

Any help is appreciated.

Thanks,

Lu
