# Overview

Carbon fields is a library which enables easy creation of custom (meta) fields in the WordPress administration panel. It allows theme developers to associate meta-information with various entities in a WordPress site (such as posts, taxonomy terms, widgets and so on).

Carbon Fields can be installed through composer (composer require htmlburger/carbon-fields).

The library supports PHP 5.3+ and uses PHP namespaces.

The main components of the library are:

  • Container – represents and controls a group of fields.
  • Field – represents a single field.
  • Data Storage – controls the underlying data storage for field values.
