AutoIt is a very simple language to learn. All that is required to write a script is logic! Although simple, you still have a wide range of resources and functions to use that allow you to create a diverse range of scripts from simple automation to making your own programs and games!
To get started, all you need to do is download the latest release of AutoIt. To begin with it is recommended you avoid downloading the beta because some of the functions may have errors which may confuse you. The latest release can be downloaded from here. The other thing you need is a text editor. Although you can use Notepad for this, it does not have some of the functionality that other specialist text editors provide such as syntax highlighting, text prediction and running the script from the editor. The editor that most AutoIt members use is a custom built version of SciTE. This has a huge advantage over other editors in that it contains addons such as Tidy and Obfuscator. Although these can be downloaded separately, they are much easier to use from within SciTE. To learn more about SciTE, see Development Environment.

Many experienced AutoIt users have also written extensive tutorials to help people get started. These may concentrate on specific elements of AutoIt such as graphics, automation, or even more advanced aspects such as TCP and Dll use! However, there are several general tutorials that are great for both learning the commands, syntax, and the layout of a script.
A list of tutorials can be found in Tutorials.
