I am clearly a complete idiot....
I am migrating from Blogger.
Since there appears to be no way to install the Share This rotating button à la Blogger on the online version of WordPress, I have downloaded version 2.8.3.
I cannot for the life of me understand how the five minute installation works. To wit....
nstallation: Famous 5-minute install
Unzip the package in an empty directory. DONE
Open up wp-config-sample.php with a text editor like WordPad or similar (DONE, in Notepad) and fill in your database connection details. WHAT ARE THESE?
The rest is irrelevant for now as I have no idea what my database connection details are.
Save the file as wp-config.php
Open /wp-admin/install.php in your browser. This should setup the tables needed for your blog. If there is an error, double check your wp-config.php file, and try again. If it fails again, please go to the support forums with as much data as you can gather.
Note the password given to you.
The install script should then send you to the login page. Sign in with the username admin and the password generated during the installation. You can then click on 'Profile' to change the password.
