h1 tag for homepage

Hiim trying to change the h1 tag for my homepage, but after having made a few adjustments it still doesnt work and now shows as a error in my code. originally i think the h1 was set as the alt text of my logo. see below the code now, but can you please advise what ive done wrong in the code and how to rectify it so that the h1 tag is the text i have written:

class="site-logo" href="{{ routes.root_url }}"> {% if section.settings.logo %} {% assign logo_alt = section.settings.logo.alt %} {% if logo_alt == '' %} {% assign logo_alt = shop.name | strip %} {% endif %}

{% if template == ‘index’ %}

{% endif %} {% render 'rimg', img: section.settings.logo, class: 'site-logo-image', alt: logo_alt, size: logo_size, focal_point: section.settings.logo.presentation.focal_point, %} {% if template == 'index' %}

{% endif %} {% else %} {% if template == 'index' %}
