+## Example
 
-    gremlins.createHorde()
+### Simple example
-        .before(function(done) {
-            var horde = this;
-            setTimeout(function(){
-                horde.log('async');
-                done();
-            }, 500);

-        .before(function() {
-            this.log('sync');
-        })
-        .gremlin(gremlins.species.formFiller())
-        .gremlin(gremlins.species.clicker().clickTypes(['click']))
-        .gremlin(gremlins.species.scroller())
-        .gremlin(function() {
-            alert('here');
-        })
-        .after(function() {
-            this.log('finished!');
-        })
-        .mogwai(gremlins.mogwais.alert())
-        .mogwai(gremlins.mogwais.fps())

+
+### Custom gremlins
+
+```js
+gremlins.createHorde()
+  .allGremlins()
+  .gremlin(function () {
+    document.activeElement.blur()
+  })
+```
+{: data-line="3,4,5"}
+
+Runs the given function at regular intervals.
+
+### Full example
+
+```js
+gremlins.createHorde()
+  .gremlin(gremlins.species.formFiller())
+  .gremlin(gremlins.species.clicker()
+    .clickTypes(['click'])
+    .canClick(element => { ··· })
+    .showAction((x, y) => { ··· }))
+  .gremlin(gremlins.species.scroller())
+  .mogwai(gremlins.mogwais.alert())
+  .mogwai(gremlins.mogwais.fps())
+  .mogwai(gremlins.mogwais.gizmo().maxErrors(2))
+  .unleash()
+```
+
+By default, all gremlins and mogwais species are added to the horde. Do it this way to customize gremlins.
