Downloading the WordPress software

Without further ado, get the latest version of the WordPress software at

http://wordpress.org/download.

WordPress gives you two compression formats for the software: .zip and
.tar.gz. We recommend getting the Zip file because it’s the most common
format for compressed files and both Windows and Mac operating systems
can use the format. Generally, the .tar.gz file format is used for Unix
operating systems.

Download the WordPress software to your computer and then decompress
(unpack or unzip) it to a folder on your computer’s hard drive. These steps
begin the installation process for WordPress. Having the program on your
own computer isn’t enough, however. You also need to upload (or transfer)
it to your Web server account .
