 ## Installation
 
-If not available as a package, `autoreverse` should compile and run on most Unix-like
-systems which support the [go](https://go.dev) compiler. It also cross-compiles and run on
-Windows.
+Regardless of how you compile or install `autoreverse` you'll need a recent version of
+[go](https://golang.org). 1.17 or later is recommended.
 
+### Installation the 'go' way
 
-### Prerequisites
-
-To compile `autoreverse` you need a recent version of [go](https://golang.org). 1.17 or
-later is recommended.

-### Target Systems and cross-compiling
-
-`autoreverse` has been tested on various CPU architectures with FreeBSD, Linux and
-macOS. The [Makefile](./Makefile) in the installation directory builds and installs
-`autoreverse` into `/usr/local/sbin`. Modify as necessary.
+```sh
+go install https://github.com/markdingo/autoreverse
+```
 
-`autoreverse` *may* compile and run on Windows but you can also cross-compile to Windows
-on a Unix-like system. To assist in this the Makefile contains the `windowsamd64` and
-`windows386` targets.
+should result in an `autoreverse` executable in `$GOPATH/bin` or `$HOME/go/bin`.
 
-Perhaps of most interest to residential deployments is the possibility of installing
-`autoreverse` on your gateway router. To that end, the Makefile has targets for a
-few *prosumer* routers such as Ubiquiti Edge Routers and Mikrotik Router Boards. It should
-be possible to target other platforms too! This project is very interested to hear of
-attempts to install `autoreverse` on gateway routers so please provide feedback of
-successes *and* failures.
+While the simplicity of installing the 'go' way has its merits, it
+doesn't install in traditional Unix locations, nor does it install the
+manpage. To do that you'll need to compile and install the 'Unix' way
