Help Center Adding to a site
When you have a URL hash, the next step is to add functionalities to the website. This is done by adding a single line to the HTML page.
Most commonly, the javascript call is added in the HEAD element of a website, but you are free to add this elsewhere.
The exact code to add to the website can be found on the page 'Hash an URL'. After creating a hash you will see the hash filled in the code ready for use.
