In some rare cases Super Bar will not be able to automatically add the snippet to your theme. Not to worry though, manual installation is a breeze.
Step 1: Copy the snippet
Start by coping the manual installation snippet found on the installation page.
Step 2: Duplicate your theme
Next you'll want to head to Online Store > Themes and make a duplicate of your theme. This is done as a precaution in case anything goes wrong.
Step 3: Open the code editor
Open the code editor on your theme by going to Actions > Edit Code.
Step 4: Open the theme.liquid file
On the left sidebar you'll see a big list of all the files that make up your theme. Open the theme.liquid file located in the layout section.
Step 5: Paste in the snippet before the closing body
Scroll to the bottom of the file and locate the closing
</body> tag. Make sure it is
</body> exactly and NOT
<body>. Paste the copied snippet on a new line above.
