 1 | YOURLS Case Insensitive Plugin
 2 | ==============================
 3 | 
 4 | Makes all keywords case insensitive (creates all keywords and calls all keywords lowercase.) Only works if you are using Base 36. Fixes disappearing capital letters.
 5 | 
 6 | Installation
 7 | ------------
 8 | 
 9 | Move the `case-insensitive` folder into the `/users/plugins` folder. Then, activate the plugin in the admin interface. That's all there is to it.
10 | 
11 | Requirements
12 | ------------
13 | 
14 | User must have [YOURLS](http://yourls.org/#Install) 1.5.1+ installed.
15 | 
16 | Bonus
17 | -----
18 | 
19 | Works with [YOURLS QR Code Plugin](https://github.com/seandrickson/yourls-qrcode-plugin) to generate smaller QR codes! This is because QR codes store upper-case characters significantly more efficiently than lower-case (ratio 5.5:8)
20 | 
21 | Credits
22 | -------
23 | 
24 | Borrowed code from Ozh's [Force Lowercase](https://github.com/YOURLS/force-lowercase) plugin
