Thanks! I like your videos, although the ENG subtitles don't work for me, and unfortunately, my poor German makes it hard to understand.
There's a subtitle button at the bottom of the video or in your app's settings, depending on what you're using. In a browser, you'll find the settings for different languages right next to it (gear icon > Subtitle settings). Simply select your language there, and you should see at least a reasonably good translation. 🙂
