+<?php

+
+Register your helper class:
+
+```php
+$this->helper->register('myHelper', '\Kanboard\Plugin\MyPlugin\Helper\MyHelper');
+```
+
+Using your helper from a template:
+
+```php
+<p>
+    <?= $this->myHelper->doSomething() ?>
+</p>
+```
+
+Using your helper from another class:
+
+```php
+$this->helper->myHelper->doSomething();
