Um, actually, the goal of most commonly used software is ease of installation and ease of use. You want people to use your software, and as such you should actual care enough to try and make things easy to understand. Not take the elitist route and say "well I explained it for an advanced user, so if you don't understand it, you are not advanced and I do not want your money (via donating to remove watermark)." This is not the right way to go about it. Even if it was, though, the way you have your site setup to "explain" to the advanced users on how to install is very vague. For example, http://www.glass8.eu/guide.htmlis not even up to date remotely. This isn't even correct in the sense that you made installers for the users. One does not even need to do anything as far as registry editing is concerned. Also, registry editing is NOT considered to be a basic system knowledge. Registry editing is very dangerous, even for the advanced users and is often taught to basic system users to not be tampered with and at the very least to make a backup of the registry in the event one messes up their system by editing something incorrectly. You also improperly and confusingly add lower down the page to in fact use the installer anyway! So do you not want them to install the software if they don't know how to edit the registry or install it regardless? The rest of the page is mostly complete (while still innacurate to a varying degree in that one does not need to make registry edits as you provide installers and a GUI tool to make changes). However, for the Windows 8 portion, you don't even make mention on how to inject your executables. You just say that they need to do so. I am a long time OS X users coming from Windows XP and Vista and I appreciate the glass looks of Windows and would love to have them on Windows 8 for example, and even though I am quite competent with OS X, I am still somewhat behind on some Windows things, so showing even the advanced users on how to do such a thing to get your software running would be helpful in the so called guide. But as most users moved on to 8.1 and 10, this is basically irrelevant again using your installers. All that being said, my only question is this; Why then does the "guide" page still exist? If it were I, I would delete it, and leave the main page as is with the exception of adding a third download for the GUI application and label it as beta. I would then add a portion to the page saying "Want to remove the watermark? Donate, then follow the instructions in the email!" Add the instructions in the email with the login info and stuff as you already have. As the "testing" page has no links to any downloadable files, you should just remove it. It's confusing. If you want to keep a guide page, I would provide a guide on how to create a theme atlas and load it. Also, you should make the "Login to your account" link much more noticeable. It's tucked away in a hard to see spot for the user, and almost tricks one into thinking they have to donate again to access their donation.key files. Please note, this is constructive criticism, nothing personal.
