Go to Giants Developer Network (GDN) downloads page.
Unfortunately you have to register account to download anything from GDN. You obviously need an account to post messages into GDN Forum but its quite bad when you have to register to download, you should never have to do that, but it is what it is. If you don't want to register, then you can download latest Giants Software from PMC download mirror.
In GDN downloads section you'll find "Editor", this is where Giants Editor versions are available for download.
The description reads depending on the installer version like: "GIANTS Editor v10.0.3 (Farming Simulator 25)".
Click the latest version available at the time you're reading this and then Giants Editor installer is downloaded. You need to refer to your web browser settings where the file was downloaded, its beyond the scope of this tutorial.
Now you are ready to read HOWTO Install Giants Editor page.
