+# go-wordwrap
+
+`go-wordwrap` (Golang package: `wordwrap`) is a package for Go that
+automatically wraps words into multiple lines. The primary use case for this
+is in formatting CLI output, but of course word wrapping is a generally useful
+thing to do.
+
+## Installation and Usage
+
+Install using `go get github.com/mitchellh/go-wordwrap`.
+
+Full documentation is available at
+http://godoc.org/github.com/mitchellh/go-wordwrap
+
+Below is an example of its usage ignoring errors:
+
+```go
+wrapped := wordwrap.WrapString("foo bar baz", 3)
+fmt.Println(wrapped)
+```
+
+Would output:
+
+```
+foo
+bar
+baz
+```
+
+## Word Wrap Algorithm
+
+This library doesn't use any clever algorithm for word wrapping. The wrapping
+is actually very naive: whenever there is whitespace or an explicit linebreak.
+The goal of this library is for word wrapping CLI output, so the input is
+typically pretty well controlled human language. Because of this, the naive
+approach typically works just fine.
+
+In the future, we'd like to make the algorithm more advanced. We would do
+so without breaking the API.
