 # BTButton
 
-BTButton is a UIButton subclass for iOS 7. With BTButton, you can create round buttons and rounded rect buttons with ease.
+BTButton is a UIButton subclass for iOS 7. Although many argue that one should not subclass UIButton, all BTButton does is add a couple methods that make styling buttons in iOS applcations much simpler.
+
+Take a look at the included demo app in order to get a full understanding of how BTButton works.
+
+## Installation
+
+To use BTButton in you projects, you can simply add `pod BTButton, '~> 1.0.0'` to your Podfile, if you're using CocoaPods. If you prefer the manual route, just add the contents of the BTButton folder to your project. Super simple!
+
+## Usage
+
+Taking inspiration from Apple's push to using NSAttributedStrings throughout iOS 7, BTButton uses one simple method to set the style of a button. The currently supported customizations are:
+
+* Corner Radius
+* Fill Color
+* Border Color
+* Border Width
+
+By using different combinations of these attributes, you can create a handful of different effects, such as a red button with a white label and a 5 pixel corner radius:
+
+```obj-c
+NSAttributedString *title =
+    [[NSAttributedString alloc] initWithString:@"Button"
+                                    attributes:@{NSForegroundColorAttributeName:[UIColor whiteColor]}];
+
+BTButton *button = [BTButton new];
+[button setStyleAttributes:@{BTButtonCornerRadiusName:@(5.0f),
+                             BTButtonFillColorName:[UIColor red]}
+           forControlState:UIControlStateNormal];
+[button setAttributedTitle:title forControlState:UIControlStateNormal];
+[button sizeToFit];
+```
