 This example includes all level A rules except for valid-lang, and in addition will include the level AA color-contrast rule.
 
-5. Run only some tags, but exclude others
-
-Similar to scope, the runOnly option can accept an object with an 'include' and 'exclude' property. Only those checks that match an included tag will run, except those that share a tag from the exclude list.
-
-```js
-axe.run(
-	{
-		runOnly: {
-			type: 'tags',
-			values: {
-				include: ['wcag2a', 'wcag2aa'],
-				exclude: ['experimental']
-			}
-		}
-	},
-	(err, results) => {
-		// ...
-	}
-);
-```
-
-This example first includes all `wcag2a` and `wcag2aa` rules. All rules that are tagged as `experimental` are than removed from the list of rules to run.
-
 6. Only process certain types of results
 
 The `resultTypes` option can be used to limit the number of nodes for a rule to a maximum of one. This can be useful for improving performance on very large or complicated pages when you are only interested in certain types of results.
