Video, 80 seconds, no sound: the click path as a diagram, step by step. No screenshots; the same steps are below for reading.

Diagram, not a screenshot. Your provider's interface may look different.

Step by step

In the Shopify admin open “Online Store” → “Themes”.
On your current theme click the three dots and first “Duplicate”. That gives you a backup.
Click the three dots again and then “Edit code”.
In the “Layout” folder open the file “theme.liquid”.
Look for the line </body> at the very bottom and paste the line of code directly above it.
Click “Save”.

Your line of code

Good to know

According to Shopify, code changes can be lost when a theme is updated. After an update, use “Check installation” to see whether the line is still there.
Shopify recommends changing theme code only if you are confident doing so. Otherwise use the button “Create an email to my web designer”.
