+### Text element
+Text elements can be created with a single style applied.
+```javascript
+var text = draw.text({
+  text: "svg\nto\nthe\npoint.",
+  x:    300,
+  y:    0
+});
+```
+Styling text can be done using the 'font()' method:
+```javascript
+text.font({
+  family: 'Helvetica',
+  size: 36,
+  anchor: 'middle',
+  leading: 1.5
+});
+```

 ### Image element
 When creating images the width and height values should be defined:
