Plugin configuration 87% from 29 tests

readme.txt 88% from 16 tests

The readme.txt file is important because it is parsed by WordPress.org for the public listing of your plugin
These attributes need your attention:
  • Screenshots: No descriptions were found for these screenshots #3, #4 in easy-flashcards/assets to your readme.txt
  • Donate link: Invalid URI ("")
The official readme.txt is a good inspiration

easy-flashcards/ef_install.php 85% from 13 tests

The main file in "Easy Flashcards" v. 0.1 serves as a complement to information provided in readme.txt and as the entry point to the plugin
You should first fix the following items:
  • Description: Please keep the plugin description shorter than 140 characters (currently 165 characters long)
  • Main file name: Even though not officially enforced, the main plugin file should be the same as the plugin slug ("easy-flashcards.php" instead of "ef_install.php")
