+
+SpectaQL is a Node.js library that generates static documentation for a GraphQL schema using a variety of options:
+
+* From a live endpoint using the introspection query.
+* From a file containing an introspection query result.
+* From a file, files or glob leading to the schema definitions in SDL.
+
+Out of the box, SpectaQL generates a single 3-column HTML page and lets you choose between a couple built-in themes. A main goal of the project is to be easily and extremely customizable--it is themeable and just about everything can be overridden or customized.
+
+```sh
+npm install --dev spectaql
+# OR
+yarn add -D spectaql
+
+# Then generate your docs
+npm run spectaql my-config.yml
+# OR
+yarn spectaql my-config.yml
+```
