+# Go support for Mobile devices
+
+[![Go Reference](https://pkg.go.dev/badge/golang.org/x/mobile.svg)](https://pkg.go.dev/golang.org/x/mobile)
+
+The Go mobile repository holds packages and build tools for using Go on mobile platforms.
+
+Package documentation as a starting point:
+
+- [Building all-Go apps](https://golang.org/x/mobile/app)
+- [Building libraries for SDK apps](https://golang.org/x/mobile/cmd/gobind)
+
+![Caution image](doc/caution.png)
+
+The Go Mobile project is experimental. Use this at your own risk.
+While we are working hard to improve it, neither Google nor the Go
+team can provide end-user support.
+
+This is early work and installing the build system requires Go 1.5.
+Follow the instructions on
+[golang.org/wiki/Mobile](https://golang.org/wiki/Mobile)
+to install the gomobile command, build the
+[basic](https://golang.org/x/mobile/example/basic)
+and the [bind](https://golang.org/x/mobile/example/bind) example apps.
