+/**
+ * This class provides easy integration with
+ * {@link https://github.com/Exercise/HTMLPurifierBundle Exercise/HTMLPurifierBundle}
+ * for Symfony-based apps.
+ *
+ * Because {@see \Exercise\HTMLPurifierBundle\HTMLPurifierConfigFactory} does not support
+ * ustom config classes ({@link https://github.com/Exercise/HTMLPurifierBundle/issues/60 related issue}),
+ * the injection of HTML5 config instance must be done inside the Purifier service itself.
+ *
+ * This class is not intended for direct use or outside Symfony apps, as it adds extra overhead
+ * related to config instantiation, required to overcome limitations of the HTMLPurifierBundle.
+ *
+ * To use HTML5 purifier as a default profile add the following to <code>services.yaml</code>:
+ *
+ * <pre>
+ * services:
+ *     exercise_html_purifier.default:
+ *         class: HTMLPurifier_HTML5
+ *         tags:
+ *             - name: exercise.html_purifier
+ *               profile: default
+ * </pre>
+ *
+ * To use it as any other profile please consult
+ * {@link https://github.com/Exercise/HTMLPurifierBundle/blob/master/README.md HTMLPurifierBundle documentation}.
