# CodeIgniter 4 Framework ## What is CodeIgniter? CodeIgniter is a PHP full-stack web framework that is light, fast, flexible and secure. More information can be found at the [official site](https://codeigniter.com). This repository holds the distributable version of the framework. It has been built from the [development repository](https://github.com/codeigniter4/CodeIgniter4). More information about the plans for version 4 can be found in [CodeIgniter 4](https://forum.codeigniter.com/forumdisplay.php?fid=28) on the forums. You can read the [user guide](https://codeigniter.com/user_guide/) corresponding to the latest version of the framework. ## Important Change with index.php `index.php` is no longer in the root of the project! It has been moved inside the *public* folder, for better security and separation of components. This means that you should configure your web server to "point" to your project's *public* folder, and not to the project root. A better practice would be to configure a virtual host to point there. A poor practice would be to point your web server to the project root and expect to enter *public/...*, as the rest of your logic and the framework are exposed. **Please** read the user guide for a better explanation of how CI4 works! ## Repository Management We use GitHub issues, in our main repository, to track **BUGS** and to track approved **DEVELOPMENT** work packages. We use our [forum](http://forum.codeigniter.com) to provide SUPPORT and to discuss FEATURE REQUESTS. This repository is a "distribution" one, built by our release preparation script. Problems with it can be raised on our forum, or as issues in the main repository. ## Contributing We welcome contributions from the community.
