13	+
14	+ Uber Login Logo is a simple plugin I made so that I could customise the login screen on my own website by utilising in-built WordPress functions and the WordPress media uploader.
15	+ Considering all the bloated plugins and resource intensive implementations floating around, I thought this lightweight codebase and clean UI could be of similar benefit to other WordPress users/developers.
16	+ Don't expect too many fancy bells and whistles, this plugin does one thing, and does it well.
17	+
18	+ == Installation ==
19	+
20	+ Download and activate from the Plugins page of your WordPress site.
21	+
22	+ == Frequently Asked Questions ==
23	+
24	+ = Will you add X feature? =
25	+
26	+ I'd like to keep this plugin simple, but if you think you have a good idea leave a comment on the [plugin page](http://www.uberweb.com.au/uber-login-logo-wordpress-plugin/) and I'll at least consider it.
27	+
28	+ == Screenshots ==
29	+
30	+ 1. How awesome your login screen could look after using this plugin.
31	+
32	+ 2. The oh so simple settings page.
33	+
34	+ == Changelog ==
35	+
36	+ = Version 0.1 =
37	+
38	+ * The first release.
