+
+**Positioning tooltips and popovers is difficult. Popper is here to help!**
+
+Given an element, such as a button, and a tooltip element describing it, Popper
+will automatically put the tooltip in the right place near the button.
+
+It will position _any_ UI element that "pops out" from the flow of your document
+and floats near a target element. The most common example is a tooltip, but it
+also includes popovers, drop-downs, and more. All of these can be generically
+described as a "popper" element.
+
+## Demo
+
+[![Popper visualized](https://i.imgur.com/F7qWsmV.jpg)](https://popper.js.org)
+
+## Docs
+
+- [v2.x (latest)](https://popper.js.org/docs/v2/)
+- [v1.x](https://popper.js.org/docs/v1/)
+
+We've created a
+[Migration Guide](https://popper.js.org/docs/v2/migration-guide/) to help you
+migrate from Popper 1 to Popper 2.
+
+To contribute to the Popper website and documentation, please visit the
+[dedicated repository](https://github.com/popperjs/website).
+
+## Why not use pure CSS?
+
+- **Clipping and overflow issues**: Pure CSS poppers will not be prevented from
+  overflowing clipping boundaries, such as the viewport. It will get partially
+  cut off or overflows if it's near the edge since there is no dynamic
+  positioning logic. When using Popper, your popper will always be positioned in
+  the right place without needing manual adjustments.
+- **No flipping**: CSS poppers will not flip to a different placement to fit
+  better in view if necessary. While you can manually adjust for the main axis
+  overflow, this feature cannot be achieved via CSS alone. Popper automatically
+  flips the tooltip to make it fit in view as best as possible for the user.
+- **No virtual positioning**: CSS poppers cannot follow the mouse cursor or be
+  used as a context menu. Popper allows you to position your tooltip relative to
+  any coordinates you desire.
+- **Slower development cycle**: When pure CSS is used to position popper
+  elements, the lack of dynamic positioning means they must be carefully placed
+  to consider overflow on all screen sizes. In reusable component libraries,
+  this means a developer can't just add the component anywhere on the page,
+  because these issues need to be considered and adjusted for every time. With
+  Popper, you can place your elements anywhere and they will be positioned
+  correctly, without needing to consider different screen sizes, layouts, etc.
+  This massively speeds up development time because this work is automatically
+  offloaded to Popper.
+- **Lack of extensibility**: CSS poppers cannot be easily extended to fit any
+  arbitrary use case you may need to adjust for. Popper is built with
+  extensibility in mind.
+
+## Why Popper?
+
+With the CSS drawbacks out of the way, we now move on to Popper in the
+JavaScript space itself.
+
+Naive JavaScript tooltip implementations usually have the following problems:
+
+- **Scrolling containers**: They don't ensure the tooltip stays with the
+  reference element while scrolling when inside any number of scrolling
+  containers.
+- **DOM context**: They often require the tooltip move outside of its original
+  DOM context because they don't handle `offsetParent` contexts.
+- **Compatibility**: Popper handles an incredible number of edge cases regarding
+  different browsers and environments (mobile viewports, RTL, scrollbars enabled
+  or disabled, etc.). Popper is a popular and well-maintained library, so you
+  can be confident positioning will work for your users on any device.
+- **Configurability**: They often lack advanced configurability to suit any
+  possible use case.
+- **Size**: They are usually relatively large in size, or require an ancient
+  jQuery dependency.
+- **Performance**: They often have runtime performance issues and update the
+  tooltip position too slowly.
+
+**Popper solves all of these key problems in an elegant, performant manner.** It
+is a lightweight ~3 kB library that aims to provide a reliable and extensible
+positioning engine you can use to ensure all your popper elements are positioned
+in the right place.
+
+When you start writing your own popper implementation, you'll quickly run into
+all of the problems mentioned above. These widgets are incredibly common in our
+UIs; we've done the hard work figuring this out so you don't need to spend hours
+fixing and handling numerous edge cases that we already ran into while building
+the library!
+
+Popper is used in popular libraries like Bootstrap, Foundation, Material UI, and
+more. It's likely you've already used popper elements on the web positioned by
+Popper at some point in the past few years.
+
+Since we write UIs using powerful abstraction libraries such as React or Angular
+nowadays, you'll also be glad to know Popper can fully integrate with them and
+be a good citizen together with your other components. Check out `react-popper`
+for the official Popper wrapper for React.
+
+## Installation
+
+### 1. Package Manager
+
+```bash
+# With npm
+npm i @popperjs/core
+
+# With Yarn
+yarn add @popperjs/core
+```
+
+### 2. CDN
+
+```html
+<!-- Development version -->
+<script src="https://unpkg.com/@popperjs/core@2/dist/umd/popper.js"></script>
+
+<!-- Production version -->
+<script src="https://unpkg.com/@popperjs/core@2"></script>
+```
+
+### 3. Direct Download?
+
+Managing dependencies by "directly downloading" them and placing them into your
+source code is not recommended for a variety of reasons, including missing out
+on feat/fix updates easily. Please use a versioning management system like a CDN
+or npm/Yarn.
+
+## Usage
+
+The most straightforward way to get started is to import Popper from the `unpkg`
+CDN, which includes all of its features. You can call the `Popper.createPopper`
+constructor to create new popper instances.
+
+Here is a complete example:
+
+```html
+<!DOCTYPE html>
+<title>Popper example</title>
+
+<style>
+  #tooltip {
+    background-color: #333;
+    color: white;
+    padding: 5px 10px;
+    border-radius: 4px;
+    font-size: 13px;
+  }
+</style>
+
+<button id="button" aria-describedby="tooltip">I'm a button</button>
+<div id="tooltip" role="tooltip">I'm a tooltip</div>
+
+<script src="https://unpkg.com/@popperjs/core@^2.0.0"></script>
+<script>
+  const button = document.querySelector('#button');
+  const tooltip = document.querySelector('#tooltip');
+
+  // Pass the button, the tooltip, and some options, and Popper will do the
+  // magic positioning for you:
+  Popper.createPopper(button, tooltip, {
+    placement: 'right',
+  });
+</script>
+```
+
+Visit the [tutorial](https://popper.js.org/docs/v2/tutorial/) for an example of
+how to build your own tooltip from scratch using Popper.
+
+### Module bundlers
+
+You can import the `createPopper` constructor from the fully-featured file:
+
+```js
+import { createPopper } from '@popperjs/core';
+
+const button = document.querySelector('#button');
+const tooltip = document.querySelector('#tooltip');
+
+// Pass the button, the tooltip, and some options, and Popper will do the
+// magic positioning for you:
+createPopper(button, tooltip, {
+  placement: 'right',
+});
+```
+
+All the modifiers listed in the docs menu will be enabled and "just work", so
+you don't need to think about setting Popper up. The size of Popper including
+all of its features is about 5 kB minzipped, but it may grow a bit in the
+future.
+
+#### Popper Lite (tree-shaking)
+
+If bundle size is important, you'll want to take advantage of tree-shaking. The
+library is built in a modular way to allow to import only the parts you really
+need.
+
+```js
+import { createPopperLite as createPopper } from '@popperjs/core';
+```
+
+The Lite version includes the most necessary modifiers that will compute the
+offsets of the popper, compute and add the positioning styles, and add event
+listeners. This is close in bundle size to pure CSS tooltip libraries, and
+behaves somewhat similarly.
+
+However, this does not include the features that makes Popper truly useful.
+
+The two most useful modifiers not included in Lite are `preventOverflow` and
+`flip`:
+
+```js
+import {
+  createPopperLite as createPopper,
+  preventOverflow,
+  flip,
+} from '@popperjs/core';
+
+const button = document.querySelector('#button');
+const tooltip = document.querySelector('#tooltip');
+
+createPopper(button, tooltip, {
+  modifiers: [preventOverflow, flip],
+});
+```
+
+As you make more poppers, you may be finding yourself needing other modifiers
+provided by the library.
+
+See [tree-shaking](https://popper.js.org/docs/v2/performance/#tree-shaking) for more
+information.
+
+## Distribution targets
+
+Popper is distributed in 3 different versions, in 3 different file formats.
+
+The 3 file formats are:
+
+- `esm` (works with `import` syntax — **recommended**)
+- `umd` (works with `<script>` tags or RequireJS)
+- `cjs` (works with `require()` syntax)
+
+There are two different `esm` builds, one for bundler consumers (e.g. webpack,
+Rollup, etc..), which is located under `/lib`, and one for browsers with native
+support for ES Modules, under `/dist/esm`. The only difference within the two,
+is that the browser-compatible version doesn't make use of
+`process.env.NODE_ENV` to run development checks.
+
+The 3 versions are:
+
+- `popper`: includes all the modifiers (features) in one file (**default**);
+- `popper-lite`: includes only the minimum amount of modifiers to provide the
+  basic functionality;
+- `popper-base`: doesn't include any modifier, you must import them separately;
+
+Below you can find the size of each version, minified and compressed with the
+[Brotli compression algorithm](https://medium.com/groww-engineering/enable-brotli-compression-in-webpack-with-fallback-to-gzip-397a57cf9fc6):
+
+<!-- Don't change the labels to use hyphens, it breaks, even when encoded -->
+
+![](https://badge-size.now.sh/https://unpkg.com/@popperjs/core/dist/umd/popper.min.js?compression=brotli&label=popper)
+![](https://badge-size.now.sh/https://unpkg.com/@popperjs/core/dist/umd/popper-lite.min.js?compression=brotli&label=popper%20lite)
+![](https://badge-size.now.sh/https://unpkg.com/@popperjs/core/dist/umd/popper-base.min.js?compression=brotli&label=popper%20base)
+
+## Hacking the library
+
+If you want to play with the library, implement new features, fix a bug you
+found, or simply experiment with it, this section is for you!
+
+First of all, make sure to have
+[Yarn installed](https://yarnpkg.com/lang/en/docs/install).
+
+Install the development dependencies:
+
+```bash
+yarn install
+```
+
+And run the development environment:
+
+```bash
+yarn dev
+```
+
+Then, simply open one the development server web page:
+
+```bash
+# macOS and Linux
+open localhost:5000
+
+# Windows
+start localhost:5000
+```
+
+From there, you can open any of the examples (`.html` files) to fiddle with
+them.
+
+Now any change you will made to the source code, will be automatically compiled,
+you just need to refresh the page.
+
+If the page is not working properly, try to go in _"Developer Tools >
+Application > Clear storage"_ and click on "_Clear site data_".  
+To run the examples you need a browser with
+[JavaScript modules via script tag support](https://caniuse.com/#feat=es6-module).
+
+## Test Suite
+
+Popper is currently tested with unit tests, and functional tests. Both of them
+are run by Jest.
+
+### Unit Tests
+
+The unit tests use JSDOM to provide a primitive document object API, they are
+used to ensure the utility functions behave as expected in isolation.
+
+### Functional Tests
+
+The functional tests run with Puppeteer, to take advantage of a complete browser
+environment. They are currently running on Chromium, and Firefox.
+
+You can run them with `yarn test:functional`. Set the `PUPPETEER_BROWSER`
+environment variable to `firefox` to run them on the Mozilla browser.
+
+The assertions are written in form of image snapshots, so that it's easy to
+assert for the correct Popper behavior without having to write a lot of offsets
+comparisons manually.
+
+You can mark a `*.test.js` file to run in the Puppeteer environment by
+prepending a `@jest-environment puppeteer` JSDoc comment to the interested file.
+
+Here's an example of a basic functional test:
+
+```js
+/**
+ * @jest-environment puppeteer
+ * @flow
+ */
+import { screenshot } from '../utils/puppeteer.js';
+
+it('should position the popper on the right', async () => {
+  const page = await browser.newPage();
+  await page.goto(`${TEST_URL}/basic.html`);
+
+  expect(await screenshot(page)).toMatchImageSnapshot();
+});
+```
+
+You can find the complete
+[`jest-puppeteer` documentation here](https://github.com/smooth-code/jest-puppeteer#api),
+and the
+[`jest-image-snapshot` documentation here](https://github.com/americanexpress/jest-image-snapshot#%EF%B8%8F-api).
