The launch of WordPress 3.0 skyrocketed the amount of tutorials available for creating Custom Post Types and Taxonomies. Anyone that has worked on highly-customized WordPress themes is familiar with the tedious process. Rest assured, the repetitiveness has been eased thanks to Themergency, a growing resource for WordPress plugins, tutorials and more.
Enormous credit must also be handed to Brad Williams, the creator of the Custom Post Type UI plugin, which has been around for quite some time. This plugin automatically takes care of the code without you having to copy and paste generated data into the functions.php file.
