+## Installing
+
+There are two options for installing gometalinter.
+
+1. Install a stable version, eg. `go get -u gopkg.in/alecthomas/gometalinter.v2`.
+   I will generally only tag a new stable version when it has passed the Travis
+  regression tests. The downside is that the binary will be called `gometalinter.v2`.
+2. Install from HEAD with: `go get -u github.com/alecthomas/gometalinter`.
