Upload the contents of the Hyperframe distribution to a suitable location on your webserver. This need not be in the root of the webspace.
Open this location in a browser, and observe whether the home page (index.htm or index.php) has the top banner and lefthand menu. If so, Hyperframe is working. Note that you must open the site through the webserver's URL. Opening the page directly as a file will not work, because this is a php site and therefore requires server interaction.
Once you have the basic page display working, add the text '?admin' to the page's URL. This should cause the hyperbar (Hyperframe toolbar) to appear at the top of the page. Log in with 'admin' and 'hyperframe' as the default username and password. If the login is successful the bar should change to a dropdown menu.
If the installation is on a publicly-visible server, you should now immediately change the default password to something more secure. Go to Tools>User Management and select the admin user. Enter a new password and press Save. Log out and log back in again to check that the new password has taken effect.
Congratulations, installation really is as a simple as that for a basic site on an industry-standard server.
Next, you will want to create some pages of your own, and and edit the menu accordingly. You will then need to think about designing a frame for your site.
You can then delete all of the example pages (.php and/or .htm files) in the root directory with the exception of the automatic sitemap, which you should retain. Do not delete other filetypes. In Hyperframe there is no install.php to delete post-intallation, by the way.
