+# Gold
+
+Render markdown on the CLI, with _pizzazz_!
+
+## What is it?
+
+Gold is a Golang library that allows you to use JSON based stylesheets to
+render Markdown files in the terminal. Just like CSS, you can define color and
+style attributes on Markdown elements. The difference is that you use ANSI
+color and terminal codes instead of CSS properties and hex colors.
+
+## Usage
+
+See [cmd/gold](cmd/gold/).
+
+## Example Output
+
+![Gold Dark Style](https://github.com/charmbracelet/gold/raw/master/styles/gallery/dark.png)
+
+Check out the [Gold Style Gallery](https://github.com/charmbracelet/gold/blob/master/styles/gallery/README.md)!
+
+## Colors
+
+Currently `gold` uses the [Aurora ANSI colors](https://godoc.org/github.com/logrusorgru/aurora#Index).
+
+## Development
+
+Style definitions located in `styles/` can be embedded into the binary by
+running [statik](https://github.com/rakyll/statik):
+
+```console
+statik -f -src styles -include "*.json"
+```
+
+You can re-generate screenshots of all available styles by running `gallery.sh`.
+This requires `termshot` and `pngcrush` installed on your system!
