 TDBadgedCell grew out of the need for TableViewCell badges and the lack of them in iOS (see the [article explaining this on TUAW](http://www.tuaw.com/2010/01/07/iphone-devsugar-simple-table-badges/). TDBadgedCell was written originally using CGPaths but as more people began to use TDBadgeCell the more customisation people wanted.
 
 To set the content of your badge (NSString) simply do:
-
-	cell.badgeString = @"130990";
+
+```Objective-C
+cell.badgeString = @"130990";
+```
 
 You can set _badgeColor_ and _badgeColorHighlighted_ to modify the colour of the badges:
-
-	cell.badgeColor = [UIColor colorWithRed:0.792 green:0.197 blue:0.219 alpha:1.000];
+
+```Objective-C
+cell.badgeColor = [UIColor colorWithRed:0.792 green:0.197 blue:0.219 alpha:1.000];
+```
 
 You can also specify a border radius for your badges:
 
-	cell.badge.radius = 9;
+```Objective-C
+cell.badge.radius = 9;
+```
 
 and you can also turn on shadows for the cells selected state:
 
-	cell.showShadow = YES;
+```Objective-C
+cell.showShadow = YES;
+```
 
 Below is an example of those different options enabled in the demo app.
