Quick Start Guide for those more experienced with Windows

If you are new to the world of UNIX, you may find it difficult to understand at first. This guide is not meant to be comprehensive, so we recommend that you use the many available Internet resources to become acquainted with UNIX basics (search for "UNIX basics" or "UNIX tutorial").

To install a basic Cygwin environment, run the setup.exe program and click Next at each page. The default settings are correct for most users. If you want to know more about what each option means, see the section called “Internet Setup”. Use setup.exe any time you want to update or install a Cygwin package. If you are installing Cygwin for a specific purpose, use it to install the tools that you need. For example, if you want to compile C++ programs, you need the gcc-g++ package and probably a text editor like nano. When running setup.exe, clicking on categories and packages in the package installation screen will provide you with the ability to control what is installed or updated.

Another option is to install everything by clicking on the Default field next to the All category. However, be advised that this will download and install several hundreds of megabytes of software to your computer. The best plan is probably to click on individual categories and install either entire categories or packages from the categories themselves. After installation, you can find Cygwin-specific documentation in the /usr/share/doc/Cygwin/ directory.

Developers coming from a Windows background will find a set of tools capable of writing console or GUI executables that rely on the Microsoft Win32 API. The dlltool utility may be used to write Windows Dynamically Linked Libraries (DLLs). The resource compiler windres is also provided.
