I downloaded the zip to my local computer, then ftp uploaded it to my web server. I created the /wp-content/plugins/files/ directory and ensured it is writable.
I'm not using Localization so I skipped that section.
I then enabled the CiviCRM plugin and ran the installer. I filled in the database settings, and it continued on with the Check Requirements and Install CiviCRM which completed successfully.
The part I don't understand is that the installer assigns a database administrator name and password, however the password is starred out ***** so I do not know what it is. I don't get the point of this, how can I possibly maintain or recover the database if I don't have the password credentials???
I thought that after the install it would email me those credentials but it appears to be top secret so that even me, the administrator, cannot know it. How do I obtain this password?
