Credits

Most of the Kohana source code is written by the Kohana Team. There are a few notable credits, however.

Kohana was originally a fork of CodeIgniter (CI), which is an open-source product of EllisLab. There are still many similarities between CI and Kohana, particularly in naming conventions and filesystem design, but all of the code is either new or completely rewritten.

All of the Kohana UTF-8 functions are ported from the phputf8 project.
