# Get started
Install your free trial of Eclipse and start customizing your storefront. When you're ready, purchase your copy and hit publish!
{% stepper %}
{% step %}
#### Choose theme preset
Choose from 4 presets with ready-made layouts and styles.
All presets include the same features and settings. The demos provide just a few examples — you can customize Eclipse to create storefronts as unique as your business.
{% endstep %}
{% step %}
#### Start free trial
Try Eclipse as long as you like before deciding to purchase. Click **Try theme** on the theme preset listing.
In your **Theme library**, click **Customize** to open the theme editor. All your changes will be saved when you buy the theme.
{% endstep %}
{% step %}
#### Buy and publish
hen you're ready to publish, go to your theme library and click **Buy** on your theme trial version. You can only [publish themes](https://help.shopify.com/en/manual/online-store/themes/managing-themes/publishing-themes) to your online store that you've purchased.
{% hint style="info" %}
**Licensed themes are purchased exclusively through the Shopify Theme Store.** Unlicensed themes are not supported. If you downloaded the theme from another vendor or plan to use the theme on another store, you need to take immediate action to purchase a legal licensed version.
