+# webbrowser [![Build Status](https://travis-ci.org/toqueteos/webbrowser.png?branch=master)](https://travis-ci.org/toqueteos/webbrowser) [![GoDoc](http://godoc.org/github.com/toqueteos/webbrowser?status.png)](http://godoc.org/github.com/toqueteos/webbrowser) [![Sourcegraph](https://sourcegraph.com/github.com/toqueteos/webbrowser/-/badge.svg)](https://sourcegraph.com/github.com/toqueteos/webbrowser?badge)
+
+webbrowser provides a simple API for opening web pages on your default browser.
+
+It's inspired on [Python's webbrowser](http://docs.python.org/3/library/webbrowser.html) package but lacks some of its features (open new window).
+
+It just opens a webpage, most browsers will open it on a new tab.
+
+## Installation
+
+As simple as:
+
+```bash
+go get -u github.com/toqueteos/webbrowser
+```
+
+## Usage
+
+```go
+package main
+
+import "github.com/toqueteos/webbrowser"
+
+func main() {
+    webbrowser.Open("http://golang.org")
+}
+```
+
+That's it!
+
+## Crossplatform support
+
+The package works on:
+
+- [x] `android` (verified by 3rd party)
+- [x] `darwin`
+- [x] `freebsd` (verified by 3rd party)
+- [x] `linux`
+- [x] `netbsd` (verified by 3rd party)
+- [x] `openbsd` (verified by 3rd party)
+- [x] `windows`
+
+## License
+
+It is licensed under the MIT open source license, please see the [LICENSE.md](https://github.com/toqueteos/webbrowser/blob/master/LICENSE.md) file for more information.
+
+## Thanks...
+
+Miki Tebeka wrote a nicer version that wasn't on godoc.org when I did this, [check it out!](https://bitbucket.org/tebeka/go-wise/src/d8db9bf5c4d1/desktop.go?at=default).
+
+## Already disliking it?
+
+No problem! There's alternative libraries that may be better to your needs:
+
+- https://github.com/pkg/browser, it does what webbrowser does and more!
+- https://github.com/skratchdot/open-golang, it even provides a `xdg-open` implementation in case you don't have it!
