Due to the tongue smiley, I'm not sure if you're serious enough or not, but regardless, I'll get something started:
Subject: How to Uninstall Software
One of the things that is beautiful about Mac OS X is the application bundle format. On OS X, most applications, although they look like single files, are actually folders. These folders which look like files, or "bundles" as they are called on OS X, contain not only the program itself, but all of the support files and resources it needs to run. If an application is self-contained in this manner, then chances are no installer will be needed to install all its separate parts on your hard drive. The upshot of all this is that the majority of applications on OS X can be installed simply by dragging them to your Applications folder, and can be uninstalled by dragging them to the Trash and emptying it.
Of course, there are some legitimate exceptions to this rule (and some poorly written applications which use an installer even though it's not necessary). In these cases, however, the author of the application will usually distribute an uninstaller along with the application. For some applications, the installer you used to install the application also has the ability to uninstall it. In general, though, if you didn't have to run an installer to install an application, you won't need an uninstaller to remove it.
If you really want to remove all traces of an application, you can check the Library/Preferences and Library/Application Support folders inside your home folder. There may sometimes be a file inside one or both of these folders which contains application settings, support information, etc. for the app. However, it is generally not necessary to delete these files as they usually take an insignificant amount of space on the disk, and will not cause any problems or conflicts just from being there. Plus, should you ever decide to put the application back on your hard drive and start using it again, your settings will be just how you left them if you didn't delete the preference files. Therefore, it's usually best just to leave these files alone.
In summary, in the majority of cases, all you will need to do to uninstall an app on the Mac is drag it to the Trash. It really is that simple.

Of course, feel free to modify this as you like, to make it clearer or whatever. I'm sure there are parts that could be cleaned up - I am admittedly not the best of documentation writers.
