-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
-
-## 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 1.11 or above
-- 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`
-
-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 -u 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 HMTL frontend with their applications, without resorting to creating a server and opening a browser to view it.
-
-## 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.
-  * [Serge Zaitsev](https://github.com/zserge) - Creator of [Webview](https://github.com/zserge/webview) which Wails uses for the windowing.
-
-Special Mentions:
-
-  * [Bill Kennedy](https://twitter.com/goinggodotnet) - Go guru, encourager and all-round nice guy, whose 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.
