+<!-- 🚨 HEY! HERE BEGINS THE INTERESTING STUFF 🚨 -->
+
+## Wut? Poppers?
+
+A popper is an element on the screen which "pops out" from the natural flow of your application.  
+Common examples of poppers are tooltips, popovers and drop-downs.
+
+
+## So, yet another tooltip library?
+
+Well, basically, **no**.  
+Popper.js is a **positioning engine**, its purpose is to calculate the position of an element
+to make it possible to position it near a given reference element.  
+
+The engine is completely modular and most of its features are implemented as **modifiers**
+(similar to middlewares or plugins).  
+The whole code base is written in ES2015 and its features are automatically tested on real browsers thanks to [SauceLabs](https://saucelabs.com/) and [TravisCI](https://travis-ci.org/).
+
+Popper.js has zero dependencies. No jQuery, no LoDash, nothing.  
+It's used by big companies like [Twitter in Bootstrap v4](https://getbootstrap.com/), [Microsoft in WebClipper](https://github.com/OneNoteDev/WebClipper) and [Atlassian in AtlasKit](https://aui-cdn.atlassian.com/atlaskit/registry/).
+
+### Popper.js
+
+This is the engine, the library that computes and, optionally, applies the styles to
+the poppers.
+
+Some of the key points are:
+
+- Position elements keeping them in their original DOM context (doesn't mess with your DOM!);
+- Allows to export the computed informations to integrate with React and other view libraries;
+- Supports Shadow DOM elements;
+- Completely customizable thanks to the modifiers based structure;
+
+Visit our [project page](https://fezvrasta.github.io/popper.js) to see a lot of examples of what you can do with Popper.js!
+
+Find [the documentation here](/docs/_includes/popper-documentation.md).
+
+
+### Tooltip.js
+
+Since lots of users just need a simple way to integrate powerful tooltips in their projects,
+we created **Tooltip.js**.  
+It's a small library that makes it easy to automatically create tooltips using as engine Popper.js.  
+Its API is almost identical to the famous tooltip system of Bootstrap, in this way it will be
+easy to integrate it in your projects.  
+The tooltips generated by Tooltip.js are accessible thanks to the `aria` tags.
+
+Find [the documentation here](/docs/_includes/tooltip-documentation.md).
+
+
+## Installation
+Popper.js is available on the following package managers and CDNs:
+
+| Source |                                                                                  |
+|:-------|:---------------------------------------------------------------------------------|
+| npm    | `npm install popper.js --save`                                                   |
+| yarn   | `yarn add popper.js`                                                             |
+| NuGet  | `PM> Install-Package popper.js`                                                  |
+| Bower  | `bower install popper.js --save`                     |
+| unpkg  | [`https://unpkg.com/popper.js`](https://unpkg.com/popper.js)                     |
+| cdnjs  | [`https://cdnjs.com/libraries/popper.js`](https://cdnjs.com/libraries/popper.js) |
+
+Tooltip.js as well:
+
+| Source |                                                                                  |
+|:-------|:---------------------------------------------------------------------------------|
+| npm    | `npm install tooltip.js --save`                                                  |
+| yarn   | `yarn add tooltip.js`                                                            |
+| Bower* | `bower install tooltip.js=https://unpkg.com/tooltip.js --save`                   |
+| unpkg  | [`https://unpkg.com/tooltip.js`](https://unpkg.com/tooltip.js)                   |
+| cdnjs  | [`https://cdnjs.com/libraries/popper.js`](https://cdnjs.com/libraries/popper.js) |
+
+\*: Bower isn't officially supported, it can be used to install Tooltip.js only trough the unpkg.com CDN. This method has the limitation of not being able to define a specific version of the library. Bower and Popper.js suggests to use npm or Yarn for your projects.  
+For more info, [read the related issue](https://github.com/FezVrasta/popper.js/issues/390).
+
+### Dist targets
+
+Popper.js is currently shipped with 3 targets in mind: UMD, ESM and ESNext.
+
+- UMD - Universal Module Definition: AMD, RequireJS and globals;
+- ESM - ES Modules: For webpack/Rollup or browser supporting the spec;
+- ESNext: Available in `dist/`, can be used with webpack and `babel-preset-env`;
+
+Make sure to use the right one for your needs. If you want to import it with a `<script>` tag, use UMD.
+
+## Usage
+
+Given an existing popper DOM node, ask Popper.js to position it near its button
+
+```js
+var reference = document.querySelector('.my-button');
+var popper = document.querySelector('.my-popper');
+var anotherPopper = new Popper(
+    reference,
+    popper,
+    {
+        // popper options here
+    }
+);
+```
+
+### Callbacks
+
+Popper.js supports two kinds of callbacks, the `onCreate` callback is called after
+the popper has been initalized. The `onUpdate` one is called on any subsequent update.
+
+```js
+const reference = document.querySelector('.my-button');
+const popper = document.querySelector('.my-popper');
+new Popper(reference, popper, {
+    onCreate: (data) => {
+        // data is an object containing all the informations computed
+        // by Popper.js and used to style the popper and its arrow
+        // The complete description is available in Popper.js documentation
+    },
+    onUpdate: (data) => {
+        // same as `onCreate` but called on subsequent updates
+    }
+});
+```
+
+### Writing your own modifiers
+
+Popper.js is based on a "plugin-like" architecture, most of its features are fully encapsulated "modifiers".  
+A modifier is a function that is called each time Popper.js needs to compute the position of the popper. For this reason, modifiers should be very performant to avoid bottlenecks.  
+
+To learn how to create a modifier, [read the modifiers documentation](docs/_includes/popper-documentation.md#modifiers--object)
+
+
+### React, Vue.js, Angular, AngularJS, Ember.js (etc...) integration
+
+Integrating 3rd party libraries in React or other libraries can be a pain because
+they usually alter the DOM and drive the libraries crazy.  
+Popper.js limits all its DOM modifications inside the `applyStyle` modifier,
+you can simply disable it and manually apply the popper coordinates using
+your library of choice.  
+
+For a comprehensive list of libraries that let you use Popper.js into existing
+frameworks, visit the [MENTIONS](/MENTIONS.md) page.
+
+Alternatively, you may even override your own `applyStyles` with your custom one and
+integrate Popper.js by yourself!
+
+```js
+function applyReactStyle(data) {
+    // export data in your framework and use its content to apply the style to your popper
+};
+
+const reference = document.querySelector('.my-button');
+const popper = document.querySelector('.my-popper');
+new Popper(reference, popper, {
+    modifiers: {
+        applyStyle: { enabled: false },
+        applyReactStyle: {
+            enabled: true,
+            fn: applyReactStyle,
+            order: 800,
+        },
+    },
+});
+
+```
+
+### Migration from Popper.js v0
+
+Since the API changed, we prepared some migration instructions to make it easy to upgrade to
+Popper.js v1.  
+
+https://github.com/FezVrasta/popper.js/issues/62
+
+Feel free to comment inside the issue if you have any questions.
+
+### Performances
+
+Popper.js is very performant. It usually takes 0.5ms to compute a popper's position (on an iMac with 3.5G GHz Intel Core i5).  
+This means that it will not cause any [jank](https://www.chromium.org/developers/how-tos/trace-event-profiling-tool/anatomy-of-jank), leading to a smooth user experience.
+
+## Notes
+
+### Libraries using Popper.js
+
+The aim of Popper.js is to provide a stable and powerful positioning engine ready to
+be used in 3rd party libraries.  
+
+Visit the [MENTIONS](/MENTIONS.md) page for an updated list of projects.
