**[WordPress][1]** is a PHP-based, open source content management system ([tag:cms]) for creating websites and blogs. Through its dynamic presentation of content, webmasters have the flexibility to create beautiful and useful websites easily. Through its system of filters and hooks, WordPress allows developers to extend functionality through pieces of code called functions, which can be grouped into separate executables called "plugins". It is also possible to customize a WordPress installation via the creation of custom themes.

[WordPress][1] as a content management platform should be distinguished from [wordpress.com][2], which is a hosted solution by the creators of WordPress. For a discussion of the differences, visit [WordPress.com and WordPress.org][3].

This tag is for programming-specific questions related to WordPress, especially those that involve a mix of languages and technologies (PHP, MySQL, CSS, JavaScript/jQuery and others). Questions about plugin and theme development, WordPress administration, management best practices and server configuration are best asked on Stack Exchange [WordPress Development][4]. 

History

WordPress appeared the first time in 2003 as a fork of b2, the version 1.0 was developed until January 2004. WordPress has since been improved many times through updates.
