+Android Units
+==========
+
+A utility class for converting between different Android display units
+
+
+
+Example Usage
+-------------
+
+How can I get the pixels for the display pixel (dp) measurement I have?
+```java
+float topPaddingOrSomething = AndroidUnits.DENSITY_PIXELS.toPixels(8);
+```
+
+
+Download
+--------
+
+Add via Gradle:
+```groovy
+compile 'com.github.kevelbreh:androidunits:0.1.0'
+```
+or Maven:
+```xml
+
+ com.github.kevelbre
+ androidunits
+ 0.1.0
+
+```
