Get entity/node title from ID

Hello,

In my custom theme and in a node template I set a node ID to retrieve his path.

<code>
{% set nid = 29 %}
<a class="btn btn-default" href="{{ path('entity.node.canonical', {'node': nid}) }}" role="button">{% trans %}Info{% endtrans %}</a></code>

But I don't see how to get the entity/node title from the ID.

Can you give me an example to retrieve the node title in a twig template?

Thanks.
