-# icon-captcha
-Static icon captcha, that generates a sprite.
+# Icon Captcha for PHP
+Inspired from [fabianwennink's icon captcha](https://github.com/fabianwennink/IconCaptcha-Plugin-jQuery-PHP). Although fabianwennink's icon captcha works nicely, there was some modifications to be made. The modifications are listed below:
+* Starting with not capping the icon amount, automatically calculating how many icons are there in the user's set folder.
+* Instead of having just 1 icon that needs to be selected, I modified it to have 2.
+* Instead of requesting each icon separately, we generate a sprite so that the front-end only needs to load the icons once.
+* Made noise of the icon more controllable, instead of it being capped to a limited amount (which was originally 50).
+* Addon is now more static website focused, meaning it's easier to integrate into websites that do not use JavaScript.
+
+# To-Do
+* Remove flex styling to support older browsers
+* Make the amount of icon's modifiable
+* Automatically generatable captcha, instead of c+p the current code in.
