Adding a Book now button to your website will direct users to your public booking page. You'll need to know a little bit about HTML to do this...
To access the code for the button go to Calendar and click on the Share icon on the top right, select "Share".
Scroll down the page to "Book now button", copy the code and insert the button in an appropriate area, or more than one, of your website.
If you know a thing or two about CSS, the style of the button (colour, size, padding, etc.) can be easily tweaked.
