Too Long; Didn't Read
To create an inclusive design means to allow every user to have the same pleasant experience when using your website, web or mobile app, despite various conditions they may be living with, e.g. color blindness, dyslexia, anxiety, and many more. It's not easy to consider in advance all possible use cases, but this doesn't have to be a one-time effort. It can be gradual, so you can continuously improve your designs to allow access to more vulnerable groups over time.
