Prerequisites

Step 1: Set Up Your Development Environment

1. Install Shopify CLI:

    npm install -g @shopify/cli
   

2. Authenticate Your Store:

    shopify login --store YOUR-STORE-URL.myshopify.com
   

---

Step 2: Download the Dawn Theme

1. Clone Dawn from GitHub:

    git clone https://github.com/Shopify/dawn.git
   

2. Navigate to the Theme Folder:

    cd dawn
   

3. Initialize with Shopify CLI:

    shopify theme init
   

---

Step 3: Customize the Theme Locally

Use Shopify CLI to start a local development server:

shopify theme dev --store YOUR-STORE-URL.myshopify.com

This syncs changes in real time to your store’s preview theme.

Key Customization Areas:

• Edit Templates: Modify .liquid files (e.g., product.liquid or collection.liquid) to adjust layout logic.

• Update Styles: Customize CSS in the assets/theme.css file.

• Add Sections: Create new sections in the sections/ directory to enable drag-and-drop blocks in the theme editor.

Key Customization Areas with Liquid Examples:

1. Product Template (product.liquid)

Add dynamic product details using Liquid:

{% comment %} product.liquid {% endcomment %}  
<div class="product">  
  <h1>{{ product.title }}</h1>  
  <div class="price">{{ product.price | money }}</div>  
  <div class="description">{{ product.description }}</div>  

  {% if product.available %}  
    <form action="/cart/add" method="post">  
      <input type="hidden" name="id" value="{{ product.variants.first.id }}">  
      <button type="submit">Add to Cart</button>  
    </form>  
  {% else %}  
    <p>This product is sold out.</p>  
  {% endif %}  
</div>

2. Collection Page (collection.liquid)

Loop through products in a collection:

{% comment %} collection.liquid {% endcomment %}  
<h1>{{ collection.title }}</h1>  
<div class="product-grid">  
  {% for product in collection.products %}  
    <div class="product-item">  
      <a href="{{ product.url }}">  
        <img src="{{ product.featured_image | img_url: '300x' }}" alt="{{ product.title }}">  
        <h3>{{ product.title }}</h3>  
        <p>{{ product.price | money }}</p>  
      </a>  
      {% unless product.available %}<span class="sold-out">Sold Out</span>{% endunless %}  
    </div>  
  {% endfor %}  
</div>

3. Custom Section (sections/custom-banner.liquid)

Create a reusable banner section with editable settings:

{% comment %} sections/custom-banner.liquid {% endcomment %}  
{% schema %}  
{  
  "name": "Custom Banner",  
  "settings": [  
    {  
      "type": "text",  
      "id": "heading",  
      "label": "Banner Heading",  
      "default": "Welcome to Our Store"  
    },  
    {  
      "type": "image_picker",  
      "id": "image",  
      "label": "Banner Image"  
    }  
  ],  
  "presets": [{ "name": "Custom Banner" }]  
}  
{% endschema %}  

<div class="custom-banner">  
  <img src="{{ section.settings.image | img_url: '1200x' }}" alt="Banner Image">  
  <h2>{{ section.settings.heading }}</h2>  
</div>

4. Dynamic CSS with Liquid (Optional)

{% comment %} assets/theme.css.liquid {% endcomment %}  
:root {  
  --primary-color: {{ settings.primary_color }};  
}  

.button {  
  background-color: var(--primary-color);  
}

---

Step 4: Configure Theme Settings

Dawn’s settings_schema.json file lets you define customizable options (like colors or fonts) in the Shopify admin. For example:

{  
  "name": "Colors",  
  "settings": [  
    {  
      "type": "color",  
      "id": "primary_color",  
      "label": "Primary Color",  
      "default": "#121212"  
    }  
  ]  
}

Adjust this file to expose new settings in the Theme Editor → Customize.

---

Step 5: Preview & Publish

1. Preview Changes: Use the local server or Shopify admin’s Online Store → Themes to test.

2. Publish Your Theme: Once satisfied, select Publish in the Shopify admin.
