<h2 align="center">Supporting Vue.js</h2>

Vue.js is an MIT-licensed open source project with its ongoing development made possible entirely by the support of these awesome [backers](https://github.com/vuejs/vue/blob/dev/BACKERS.md). If you'd like to join them, please consider:

- [Become a backer or sponsor on Patreon](https://www.patreon.com/evanyou).
- [Become a backer or sponsor on Open Collective](https://opencollective.com/vuejs).
- [One-time donation via PayPal or crypto-currencies](https://vuejs.org/support-vuejs/#One-time-Donations).

#### What's the difference between Patreon and OpenCollective?

Funds donated via Patreon go directly to support Evan You's full-time work on Vue.js. Funds donated via OpenCollective are managed with transparent expenses and will be used for compensating work and expenses for core team members or sponsoring community events. Your name/logo will receive proper recognition and exposure by donating on either platform.

## Introduction

Vue (pronounced `/vjuː/`, like view) is a **progressive framework** for building user interfaces. It is designed from the ground up to be incrementally adoptable, and can easily scale between a library and a framework depending on different use cases. It consists of an approachable core library that focuses on the view layer only, and an ecosystem of supporting libraries that helps you tackle complexity in large Single-Page Applications.

#### Browser Compatibility

Vue.js supports all browsers that are [ES5-compliant](https://kangax.github.io/compat-table/es5/) (IE8 and below are not supported).
