+## Building
+
+- install the [Go compiler](https://golang.org/dl)
+- run `make`
+- copy the `./asprom` binary to where you need it
+
+It's also easy to crosscompile with Go. You can build asprom for Linux on a Mac with: `GOOS=linux GOARCH=amd64 go build` and then copy the `asprom` binary over to your Linux machines.
