readme.txt 88% from 16 tests

The readme.txt file describes your plugin functionality and requirements and it is parsed to prepare the your plugin's listing
These attributes need to be fixed:
  • Tags: There are too many tags (21 tag instead of maximum 10)
  • Screenshots: Please add images for these screenshots: #1 (Shows a example content site with the generated qr code), #2 (Shows the using of the shortcode within the backend in wp-admin), #3 (The QR Code panel wp-admin), #4 (The QR Code menu setting panel wp-adim)
The official readme.txt might help

  • Description: The description should be shorter than 140 characters (currently 345 characters long)
