+# graphlib2dot
+
+This command line tool takes a graphlib JSON document and converts it into a
+dot file.
+
+## Installation
+
+Install it globally with npm
+
+```
+npm install -g graphlib2dot
+```
+
+## Usage
+
+Simply pipe your JSON document into the program:
+
+```
+cat graph.json | graphlib2dot
+```
+
+Or specify a file:
+
+```
+graphlib2dot -f graph.json
+```
+
+You can create a JSON representation of your graphlib Graph via
+`graphlib.json.write`. More info [here](https://github.com/cpettitt/graphlib/wiki/API-Reference#json-write).
