How to: cd $GOPATH/src/github.com/prometheus/alertmanager
$ alertmanager --config.file=
```

Or clone the repository and build manually:

```
$ mkdir -p $GOPATH/src/github.com/prometheus
$ cd $GOPATH/src/github.com/prometheus
$ git clone https://github.com/prometheus/alertmanager.git
$ cd alertmanager
$ make build
$ ./alertmanager --config.file=
```

You can also build just one of the binaries in this repo by passing a name to the build function:
```
$ make build BINARIES=amtool
```
