+
+uitable is a go library for representing data as tables for terminal applications. It provides primitives for sizing and wrapping columns to improve readability.
+
+## Example Usage
+
+Full source code for the example is available at [example/main.go](example/main.go)
+
+```go
+table := uitable.New()
+table.MaxColWidth = 50
+
+table.AddRow("NAME", "BIRTHDAY", "BIO")
+for _, hacker := range hackers {
+  table.AddRow(hacker.Name, hacker.Birthday, hacker.Bio)
+}
+fmt.Println(table)
+```
+
+Will render the data as:
+
+```sh
+NAME          BIRTHDAY          BIO
+Ada Lovelace  December 10, 1815 Ada was a British mathematician and writer, chi...
+Alan Turing   June 23, 1912     Alan was a British pioneering computer scientis...
+```
+
+For wrapping in two columns:
+
+```go
+table = uitable.New()
+table.MaxColWidth = 80
+table.Wrap = true // wrap columns
+
+for _, hacker := range hackers {
+  table.AddRow("Name:", hacker.Name)
+  table.AddRow("Birthday:", hacker.Birthday)
+  table.AddRow("Bio:", hacker.Bio)
+  table.AddRow("") // blank
+}
+fmt.Println(table)
+```
+
+Will render the data as:
+
+```
+Name:     Ada Lovelace
+Birthday: December 10, 1815
+Bio:      Ada was a British mathematician and writer, chiefly known for her work on
+          Charles Babbage's early mechanical general-purpose computer, the Analytical
+          Engine
+
+Name:     Alan Turing
+Birthday: June 23, 1912
+Bio:      Alan was a British pioneering computer scientist, mathematician, logician,
+          cryptanalyst and theoretical biologist

+# 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.
