Shopify Theme Installation
After you have purchased your Shopify Theme you will receive an automated email which will include a download link.
Once you have clicked on this link your theme will begin downloading as a "zipped" folder with a .zip file extension.
Do not unzip the folder.
When the theme has downloaded enter your Shopify admin and go to the Themes area.
Select the Upload a theme option and find the zipped folder.
When uploaded Shopify will auto extract the folder installing your new theme however it will remain unpublished at this point so as not to disrupt your current setup.
Return to the Manage themes page and you will see your new theme. From here you can edit, preview or publish the theme to make it live.
