Non-video tutorials for UE4?

Are there non-video tutorials for UE4? I am hearing-impaired. Will there be books for UE4?

In the wiki you can find some: A new, community-hosted Unreal Engine Wiki - Announcements and Releases - Unreal Engine Forums

The wiki is the home for all written tutorials as mentioned above. I believe we will have subtitles for the videos soon as well.
