How to Make an Addon?


How to make an addon?

I need to create an information page for my customers with dates of receipt of their orders.

In fact, I need to put a script in PHP or Smarty (I already have the scripts) on a new special dedicated only information CMS page or an other page.

```php Your order will be at your door {PHP}“Today + X Days”{/PHP} ```

How could I do?

Create an addon?

Thank you,
