Thanks for your feedback, and I'm sorry to hear that you're frustrated with the documentation. We've done a lot over the last several months to drastically improve our documentation experience (both for our users and for our documentation authors), but we also know that we can always do more to improve the volume of our content, as well as its organization.
In fairness, I would like to point out that the specific item the customer was looking for was, in fact, in the docs, and not buried in a faq that lives outside of our documentation repository. Even still, I know that "just because it's there" doesn't always mean that a doc or docs are in the right place or intuitively findable by our customers.
Along those lines, we are trying to be very open about our documentation process, and all of our docs can be found in a public, MIT-licensed GitHub repo (http://github.com/telerik/kendo-docs). In addition to making the docs public via this repo, we gladly accept both Issue reports and pull requests. So if you ever have an issue with something being missing, or you feel that key information is in the wrong place, please feel free to create an issue and let us know what way.
Have a great weekend!
