+# Termtables
+
+[![Build Status](https://travis-ci.org/scylladb/termtables.svg?branch=master)](https://travis-ci.org/scylladb/termtables)
+
+A [Go](http://golang.org) port of the Ruby library [terminal-tables](https://github.com/visionmedia/terminal-table) for
+fast and simple ASCII table generation.
+
+## Installation
+
+```bash
+go get github.com/scylladb/termtables
+```
+
+## Go Style Documentation
+
+[http://godoc.org/github.com/scylladb/termtables](http://godoc.org/github.com/scylladb/termtables)
+
+## APC Command Line usage
+
+`--markdown` — output a markdown table, e.g. `apc app list --markdown`
+
+`--html` — output an html table, e.g. `apc app list --html`
+
+`--ascii` — output an ascii table, e.g. `apc app list --ascii`
+
+## Basic Usage
+
+```go
+package main
+
+import (
+  "fmt"
+  "github.com/apcera/termtables"
+)
+
+func main() {
+  table := termtables.CreateTable()
+
+  table.AddHeaders("Name", "Age")
+  table.AddRow("John", "30")
+  table.AddRow("Sam", 18)
+  table.AddRow("Julie", 20.14)
+
+  fmt.Println(table.Render())
+}
+```
+
+Result:
+
+```
++-------+-------+
+| Name  | Age   |
++-------+-------+
+| John  | 30    |
+| Sam   | 18    |
+| Julie | 20.14 |
++-------+-------+
+```
+
+## Advanced Usage
+
+The package function-call `EnableUTF8()` will cause any tables created after
+that point to use Unicode box-drawing characters for the table lines.
+
+Calling `EnableUTF8PerLocale()` uses the C library's locale functionality to
+determine if the current locale environment variables say that the current
+character map is UTF-8.  If, and only if, so, then `EnableUTF8()` will be
+called.
+
+Calling `SetModeHTML(true)` will cause any tables created after that point
+to be emitted in HTML, while `SetModeMarkdown(true)` will trigger Markdown.
+Neither should result in changes to later API to get the different results;
+the primary intended use-case is extracting the same table, but for
+documentation.
+
+The table method `.AddSeparator()` inserts a rule line in the output.  This
+only applies in normal terminal output mode.
+
+The table method `.AddTitle()` adds a title to the table; in terminal output,
+this is an initial row; in HTML, it's a caption.  In Markdown, it's a line of
+text before the table, prefixed by `Table: `.
+
+The table method `.SetAlign()` takes an alignment and a column number
+(indexing starts at 1) and changes all _current_ cells in that column to have
+the given alignment.  It does not change the alignment of cells added to the
+table after this call.  Alignment is only stored on a per-cell basis.
+
+## Known Issues
+
+Normal output:
+
+* `.SetAlign()` does not affect headers.
+
+Markdown output mode:
+
+* When emitting Markdown, the column markers are not re-flowed if a vertical
+  bar is an element of a cell, causing an escape to take place; since Markdown
+  is often converted to HTML, this only affects text viewing.
+* A title in Markdown is not escaped against all possible forms of Markdown
+  markup (to avoid adding a dependency upon a Markdown library, as supported
+  syntax can vary).
+* Markdown requires headers, so a dummy header will be inserted if needed.
+* Table alignment is not reflected in Markdown output.
