Twig check if value in array is true

I have an array which contains booleans. How do I search the array to see if one or more is true and then display the <h1> something once?

Here is my code so far 

{% set guides = 
              [
                 product.is_user_guide,
                 product.is_product_guide,
                 product.is_installation_guide
              ] 
              %}

               {% for guide in guides %}
                  {% if (guide) %}
                  <h1>There is a guide!</h1>
                  {% endif %}
              {% endfor %}

In the above code it finds 2 values in the array to true and displays the h1 twice. How can I modify it so it only displays once?

You can use the containment operator in:

{% set guides = [
    product.is_user_guide,
    product.is_product_guide,
    product.is_installation_guide
] %}

{% if true in guides %}
   <h1>There is a guide!</h1>
{% endif %}
