I find navigating around the Stripe documenation a very frustrating experience. The series of screenshots below shows the journey, one page at a time, from the Home or Dashboard page of Stripe to the documentation for implementing a Client Only integration of Stipe Checkout Payments on your website.
It is inevitable that Stripe will tinker around with their documentation (and probably make it even more confusing). So, if the precise sequence of clicks shown in the screenshots below fail, you would probably be best to use the URLs and some of the key words to search google.
