-### Use shortcodes outside post content
-
-By default, scripts are only loaded when the shortcode is within the content.
-If you use shortcodes outside the content, ex. custom fields or by `do_shortcode`, you need to manually enqueue the scripts for the submit to work.

-```php
-wp_enqueue_script('wplf-form-js');
-wp_localize_script( 'wplf-form-js', 'ajax_object', array(

-### Client side callbacks
-
-WP Libre Form supports client side callbacks after form submission using window.wplf object. Example usage:
-
-```
-window.wplf.successCallbacks.push(function(response){

-});
-
-window.wplf.errorCallbacks.push(function(response){
-  alert("Form submission failed!");

-
-These callbacks are executed in the order they appear.
-
-### Add CSS classes to form output
-
-You can use the xclass attribute inside the shortcode to add your own extra classes.

-```

+## Contributing
+
+Please make sure your code conforms to the code style used in the rest of the plugin.
+
+We use the standard WordPress code style, with a few major exceptions to make it nicer for modern GitHub projects:
+
+* Indedation is 2 spaces, not tabs.
+* Yoda conditions aren't enforced
+
+### PHP Codesniffer
+
+This project comes with a phpcs configuration (`phpcs.xml`) you can use to check your code like so:
+
+Run phpcs in the project root directory:
+
+```
+phpcs --extensions=php --standard=./phpcs.xml -n -p .
+```
+
+Before you can run phpcs, you need to install PHP Codesniffer and WordPress coding standards like so:
+
+```
+composer create-project wp-coding-standards/wpcs:dev-master --no-dev $HOME/wpcs
+```
+
+Or read the official installation instructions here:
