-You can overwrite some of the global settings on per-element basis by using following attributes:
-* `data-aos-offset`
-* `data-aos-duration`
-* `data-aos-easing`
-* `data-aos-delay`
-* `data-aos-once`
-* `data-aos-mirror`
+#### Anchor
 
-There are also few settings that can be used only on per-element basis:
-* `data-aos-anchor` - element whose offset will be used to trigger animation instead of an actual one
-* `data-aos-anchor-placement` (default `top-bottom`) - defines which position of the element regarding to window should trigger the animation. `top-bottom` means that the animation will be triggered once top of the element hits bottom of the screen.

+## Caveats:
 
-#### setting: duration:
-*Duration accept values from 50 to 3000, with step 50ms, it's because duration of animation is handled by css, and to not make css longer than it is already I created implementations only in this range. I think this should be good for almost all cases.
+#### setting: `duration`, `delay`
 
-If not, you may write simple CSS on your page that will add another duration option value available, for example:
+Duration and delay accept values from 50 to 3000, with step 50ms, it's because those are handled by css, and to not make css longer than it is already I implemented only a subset. I believe those should cover most cases.
+
+If not, you can write simple CSS that will add another duration, for example:
 
 ```css
-  body[data-aos-duration='4000'] [data-aos], [data-aos][data-aos][data-aos-duration='4000']{
+  body[data-aos-duration='4000'] [data-aos],
+  [data-aos][data-aos][data-aos-duration='4000'] {
     transition-duration: 4000ms;
   }
 ```
-
 This code will add 4000ms duration available for you to set on AOS elements, or to set as global duration while initializing AOS script.
-
 Notice that double `[data-aos][data-aos]` - it's not a mistake, it is a trick, to make individual settings more important than global, without need to write ugly "!important" there :)
 
-#### setting: startEvent:
-If you set `startEvent: 'load'` it will add event listener on `window` instead of `document`.

+```html
+  <div data-aos="fade-in" data-aos-duration="4000"></div>
