How about some nice screenshots?

[novoid]

People love screenshots to see whether or not the visualization of the feeds within Emacs is something they want or not.

[novoid]

Or do a screencast:

Example how I did it: https://github.com/novoid/filetags/

Done using Xubuntu, https://obsproject.com/ + key-mon using the following workflow:

• plug-in external microphone
• start ose
  • one-time setup
    • settings
      • Output > Recording path
      • Output > Recording Format: mp4
      • Audio > Mic/Auxiliary Audio Device: Snowball
      • Hotkeys > Super (Windows) , and . for start/stop recording
    • setup Sources > screen capture XSHM (via +)
  • manually enlarge the red border of the capture area so that the xfce menu is out of sight
• change emacs screen size so that it matches the new capture area of ose
• start key-mon to show keyboard action
• change to Emacs
• press Windows-, to start recording and have some fun
• final mp4 lands in the Recording path set above

There is also https://gitlab.com/ambrevar/emacs-gif-screencast but I didn't look into it myself since I am very happy with the process above.
