Using Kirki theme developers can create rich experiences for the WordPress Customizer using best coding practices.

Included are 30 custom control types ranging from simple sliders to complex typography controls with Google-Fonts integration, automatic CSS generation, `postMessage` scripts automatically generated, tooltips and a lot of extras that make developing themes a lot faster for developers and meaningful for users.

We advise you to familiarize yourself with the Customizer API before you start writing your theme using Kirki. An excellent handbook for the WordPress Customizer can be found on the [developer.wordpress.org](https://developer.wordpress.org/themes/customize-api/) website.

You can find detailed documentation on how to use Kirki on [https://aristath.github.io/kirki/](https://aristath.github.io/kirki/)

[Development and issues on github](https://github.com/aristath/kirki).

== Installation ==

Simply install as a normal WordPress plugin and activate.

If you want to integrate Kirki in your theme or plugin, please read the instructions on [our ducumentation site](https://kirki.org/docs/advanced/integration.html).
