We would LOVE to get feedback on our docs and samples. The UE team is working on the RTM doc refresh and plans to do monthly refreshes thereafter - any feedback you have will help us prioritize how we can invest in our docs to make them more useful to you. So please respond back with your feedback, and I'll work with UE to action it!
