+
+The traditional method of providing web interfaces to Go programs is via a built-in web server. Wails offers a different approach: it provides the ability to wrap both Go code and a web frontend into a single binary. Tools are provided to make this easy for you by handling project creation, compilation and bundling. All you have to do is get creative!
+
+## Features
+
+- Use standard Go libraries/frameworks for the backend
+- Use any frontend technology to build your UI
+- Expose Go methods/functions to the frontend via a single bind command
+- Uses native rendering engines - no embedded browser
+- Shared events system
+- Native file dialogs
+- Powerful cli tool
+- Multiplatform
+
+## Project Status
+
+Wails is currently in Beta. Please make sure you read the [Project Status](https://wails.app/project_status.html) if you are interested in using this project.
+
+## Installation
+
+Wails uses cgo to bind to the native rendering engines so a number of platform dependent libraries are needed as well as an installation of Go. The basic requirements are:
+
+- Go 1.12
+- npm
+
+### MacOS
+
+Make sure you have the xcode command line tools installed. This can be done by running:
+
+`xcode-select --install`
+
+### Linux
+
+#### Ubuntu 18.04
+
+`sudo apt install pkg-config build-essential libgtk-3-dev libwebkit2gtk-4.0-dev`
+
+#### Arch Linux
+
+`sudo pacman -S webkit2gtk gtk3`
+
+#### Red Hat Based Distros
+
+`sudo yum install webkit2gtk-devel gtk3-devel`
+
+Note: If you have successfully installed these dependencies on a different flavour of Linux, please consider submitting a PR.
+
+### Windows
+
+Windows requires gcc and related tooling. The recommended download is from [http://tdm-gcc.tdragon.net/download](http://tdm-gcc.tdragon.net/download). Once this is installed, you are good to go.
+
+## Installation
+
+Installation is as simple as running the following command:
+
+<pre style='color:white'>
+go get github.com/wailsapp/wails/cmd/wails
+</pre>
+
+## Next Steps
+
+It is recommended at this stage to read the comprehensive documentation at [https://wails.app](https://wails.app).
+
+## FAQ
+
+ * Is this an alternative to Electron?
+
+   Depends on your requirements. It's designed to make it easy for Go programmers to make lightweight desktop applications or add a frontend to their existing applications. Whilst Wails does not currently offer hooks into native elements such as menus, this may change in the future.
+
+ * Who is this project aimed at?
+
+   Go programmers who want to bundle an HTML/JS/CSS frontend with their applications, without resorting to creating a server and opening a browser to view it.
+
+ * What's with the name?
+
+   When I saw WebView, I thought "What I really want is tooling around building a WebView app, a bit like Rails is to Ruby". So initially it was a play on words (Webview on Rails). It just so happened to also be a homophone of the English name for the [Country](https://en.wikipedia.org/wiki/Wales) I am from. So it stuck.
+
+## Shoulders of Giants
+
+Without the following people, this project would never have existed:
+
+  * [Dustin Krysak](https://wiki.ubuntu.com/bashfulrobot) - His support and feedback has been immense. More patience than you can throw a stick at (Not long now Dustin!).
+  * [Serge Zaitsev](https://github.com/zserge) - Creator of [Webview](https://github.com/zserge/webview) which Wails uses for the windowing.
+
+And without [these people](CONTRIBUTORS.md), it wouldn't be what it is today.
+
+Special Mentions:
+
+  * [Bill Kennedy](https://twitter.com/goinggodotnet) - Go guru, encourager and all-round nice guy, whose infectious energy and inspiration powered me on when I had none left.
+  * [Mark Bates](https://github.com/markbates) - Creator of [Packr](https://github.com/gobuffalo/packr), inspiration for packing strategies which fed into some of the tooling.
+
+This project was mainly coded to the following albums:
+
+  * [Manic Street Preachers - Resistance Is Futile](https://open.spotify.com/album/1R2rsEUqXjIvAbzM0yHrxA)
+  * [Manic Street Preachers - This Is My Truth, Tell Me Yours](https://open.spotify.com/album/4VzCL9kjhgGQeKCiojK1YN)
+  * [The Midnight - Endless Summer](https://open.spotify.com/album/4Krg8zvprquh7TVn9OxZn8)
+  * [Gary Newman - Savage (Songs from a Broken World)](https://open.spotify.com/album/3kMfsD07Q32HRWKRrpcexr)
+  * [Steve Vai - Passion & Warfare](https://open.spotify.com/album/0oL0OhrE2rYVns4IGj8h2m)
+  * [Ben Howard - Every Kingdom](https://open.spotify.com/album/1nJsbWm3Yy2DW1KIc1OKle)
+  * [Ben Howard - Noonday Dream](https://open.spotify.com/album/6astw05cTiXEc2OvyByaPs)
