+
+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
+- Quickly create Vue, Vuetify or React frontends for your Go programs
+- 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
+
+**Ensure Go modules are enabled: GO111MODULE=on and go/bin is in your PATH variable.**
+
+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. A huge thank you to each and every one of you!
+
+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)

+This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
+
+## Available Scripts
+
+In the project directory, you can run:
+
+### `npm start`
+
+Runs the app in the development mode.<br>
+Open [http://localhost:3000](http://localhost:3000) to view it in the browser.
+
+The page will reload if you make edits.<br>
+You will also see any lint errors in the console.
+
+### `npm test`
+
+Launches the test runner in the interactive watch mode.<br>
+See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
+
+### `npm run build`
+
+Builds the app for production to the `build` folder.<br>
+It correctly bundles React in production mode and optimizes the build for the best performance.
+
+The build is minified and the filenames include the hashes.<br>
+Your app is ready to be deployed!
+
+See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
+
+### `npm run eject`
+
+**Note: this is a one-way operation. Once you `eject`, you can’t go back!**
+
+If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
+
+Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
+
+You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
+
+## Learn More
+
+You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).
