The Hello Bar code is just a single line of JavaScript that can be placed anywhere on the HTML portion of a website. We recommend installing the code just before the closing tag on your page or site templates HTML code. 

This is where most lines of code will go, making it easier to locate at anytime should you need too. .

Some website platforms will offer a type of HTML "Input" area for lines of code, such as the Hello Bar installation script. You can use this instead of the above method, please just make sure you are installing Hello Bar a single time.
