 A fork of [https://github.com/blasten/turn.js](https://github.com/blasten/turn.js)
-with support for npm/yarn. Basically I just added a package.json file and
-specified a main entry point + a dependency (jquery)
+with support for npm/yarn.
+
+Usage:
+
+```
+import $ from 'jquery';
+import 'turn.js';
+
+$('#flipbook').turn({
+  width: 800,
+  height: 600,
+  autoCenter: true
+  // ... plus any extra option you need
+});
+```
+
+Basically I just added a package.json file and specified a main entry point + a
+dependency (jquery) to make turn.js installable via npm/yarn.
+
+I have submitted a PR to the authors of [https://github.com/blasten/turn.js](https://github.com/blasten/turn.js) but in the meantime you can use this one, as they don't seem to update their repo regularly.
+
+Latest version uses jQuery 1.12.0 because jQuery 3.x was breaking the page
+flipper.
