-# Lion
+> ## 🛠 Status: Pilot Phase
+> Lion Web Components are still in an early alpha stage; they should not be considered production ready yet.
+>
+> The goal of our pilot phase is to gather feedback from a private group of users.
+> Therefore, during this phase, we kindly ask you to:
+> - not publicly promote or link us yet: (no tweets, blog posts or other forms of communication about Lion Web Components)
+> - not publicly promote or link products derived from/based on Lion Web Components
+>
+> As soon as Pilot Phase ends we will let you know (feel free to subscribe to this issue https://github.com/ing-bank/lion/issues/1)
 
-I'm afraid a little more patience is needed.
+# Lion Web Components
 
-See you soon :)
+Lion web components is a set of highly performant, accessible and flexible Web Components.
+They provide an unopinionated, white label layer that can be extended to your own layer of components.

+
+## How to use
+
+### Use a Web Component
+
+```html
+<script type="module">
+  import '@lion/input/lion-input.js';
+</script>
+
+<lion-input name="firstName"></lion-input>
+```
+
+### Use a JavaScript system
+
+```html
+<script type="module">
+  import { ajax } from '@lion/ajax';
+
+  ajax.get('data.json').then(response => {
+    // most likely you will use response.data
+  });
+</script>
+```
+
+### Extend a Web Component
+
+```js
+import { LionInput } from '@lion/input';
+
+class MyInput extends LionInput {}
+customElements.define('my-input', MyInput);
+```
+
+## Key Features
+
+- High Performance - Focused on great performance in all relevant browsers with a minimal number of dependencies
+- Accessibility - Aimed at compliance with the WCAG 2.0 AA standard to create components that are accessible for everybody
+- Flexibility - Provides solutions through Web Components and JavaScript classes which can be used, adopted and extended to fit all needs
+
+## Technologies
+
+Lion Web Components aims to be future proof and use well-supported proven technology. The stack we have chosen should reflect this.
+
+- [lit-html](https://lit-html.polymer-project.org) and [lit-element](https://lit-element.polymer-project.org)
+- [npm](http://npmjs.com)
+- [yarn](https://yarnpkg.com)
+- [open-wc](https://open-wc.org)
+- [webpack](https://webpack.js.org)
+- [Karma](https://karma-runner.github.io)
+- [Mocha](https://mochajs.org)
+- [Chai](https://www.chaijs.com)
+- [ESLint](https://eslint.org)
+- [prettier](https://prettier.io)
+- [Storybook](https://storybook.js.org)
+- [ES modules](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import)
+- Lots and lots of tests
+
+## Rationale
+
+We know from experience that making high quality, accessible UI components is hard and time consuming:
+it takes many iterations, a lot of development time and a lot of testing to get a generic component that works in every
+context, supports many edge cases and is accessible in all relevant screen readers.
+
+Lion aims to do the heavy lifting for you.
+This means you only have to apply your own Design System: by delivering styles, configuring components and adding a minimal set of custom logic on top.
+
+## How to contribute
+
+Lion Web Components are only as good as its contributions.
+Read our [contribution guide](./CONTRIBUTING.md) and feel free to enhance/improve our product .
+
+## Support and issues
+
+As stated above "support and issues time" is currently rather limited: feel free to open a discussion.
+However, we can not guarantee any response times.
