+# Zocial CSS social buttons
+
+I basically rewrote this entire set so they are full vector buttons, meaning:
+
+- @font-face icons
+- custom font file for all social icons
+- em sizing based on button font-size
+- support for about 44 different services
+- buttons and icons supported
+- no raster images (sweet)
+- works splendidly on any browser supporting @font-face
+- CSS3 degrades gracefully in IE8 and below etc.
+
+## How to use these buttons:
+
+	<button class='zocial facebook'>
+		<span>Button label here</span>
+	</button>
+
+- Parent element can be any element e.g. `a`, `div`, `button` etc.
+- Must contain child `span` element
+- Add class of `.zocial` to parent element
+- Add class for name of service e.g. `.dropbox`, `.twitter`, `.github`
+- Done :-)
