+## Description
+This plugin provides an easy way to get involved with Beta testing WordPress.
+
+Once installed it will enable you to upgrade your website to the latest Beta or Release candidate at the click of a button using the built in upgrader.
+
+By default once enabled it switches your website onto the point release development track.
+
+For the more adventurous there is the option to switch to the bleeding edge (trunk) of development.
+
+Don't forget to backup before you start!
+
+In the **Extra Settings** tab are choices for testing features in trunk that may require constants to be set. A checked feature will add a constant to the user's `wp-config.php` file in the format as follows:
+
+`define( 'WP_BETA_TESTER_{$feature}', true );`
+
+Unchecking the feature will remove the constant.
+
+If no settings are present there is no testing to be done that requires this feature.
+
+PRs are welcome on [GitHub](https://github.com/afragen/wordpress-beta-tester).
