Downloading and installing a theme

I have chosen Multiflex by G. Wolfgang as the theme that I can customize for my Drupal site. I like its use of colors to highlight groups of content. I think that the combination of blues accented by yellows, purples, and greens gives a standard yet lively environment for interacting with information on the site. This theme didn't come with the core installation of Drupal so I had to download and install it. Here's how I did it:

• Went to Drupal's Themes page. Scrolled down to Multiflex and clicked Download.
• Unzipped the file multiflex-4.7.0.tar to the themes folder of my Drupal directory on my computer.
• Uploaded the multiflex folder to the themes folder of the Drupal installation on my hosted shared web server.
• Logged in to my Drupal site and went to administer>themes. The new theme has been added to the list of themes I can enable.
• Clicked the Enable as well as the Default buttons.

...to be continued. I'm learning how to detail my process. What level of detail is really helpful for my intended audience? I probably just need to say "download & install your chosen theme" and they know exactly the details of how to do that. We'll see.
