All i find is this: "Using this app is extremely easy. Just download, extract and launch it. Afterwards just click the "add to GOG.com Downloader" link, right below the classic download link(s) and you're good to go."

I don't get what to do. I am at my library and i only see two buttons. One that says install now which brings me to the downloader i already have installed, and a windows installer, english. What do i press to install via the downloader?

Assuming you have the downloader installed, and "Downloader Mode" set to On (Green), click the Windows Installer to download through the downloader.

Edit: Disregard this.
Novotnus had made a picture tutorial, let me see if I can find it.
Was remembering wrong, the tutorial was how to download without the downloader. Do ask if you want more info

That would be great. Downloading for dummies xD

Quick screengrab. Make sure downloader mode (1) is set to On, then click Windows Installer, English (2). The GOG downloader should intercept the link and start downloading. If nothing happens, post your browser so we can post instructions on how to enable gogdownloader links.

It works, thank you very much! Sam & Max here i come.

I would add : once your game(s) is/are downloaded, they appear as a list in the downloader. In your downloader window, you have a button at the top right "settings". Cliuck that button and you get several choices, including the option to have the installer being launched right after download. If this is not selected, you have to click the small looking glass next to each title in the downloader list, it will bring you to the folder where the installer is located. Just launch the installer ( sometimes using administrator privileges is preferable ) and here you go. A last word, to chose your install path, select the option button on the first screen after the installer launches

OK, thanks for the info. But how do i que several games? If i am downloading something and then press download on another game will it take its place or que.

Clicking on several items will queue them. Queue is game based, so adding the installer for Beneath a Steel Sky, then the installer for Tyrian 2000, then the extras for Beneath a Steel Sky, the queue will be BaSS installer, BaSS extras, Tyrian installer. If on the other hand you queue BaSS installer, Tyrian Extras, Ultima 4 installer, the queue will be BaSS installer, Tyrian Extras, Ultima 4 installer.

OK, thanks Mich.
