+# IndexedDB database adapter for [Yjs](https://github.com/y-js/yjs)
+
+Use the IndexedDB database adapter to store your shared data persistently in the browser. The next time you join the session, your changes will still be there.
+
+* Minimizes the amount of data exchanged between server and client
+* Makes offline editing possible
+* Not supported by all browsers (see [mdn](https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API))
+
+## Use it!
+Install this with bower or npm.
+
+##### Bower
+```
+bower install y-indexeddb --save
+```
+
+##### NPM
+```
+npm install y-indexeddb --save
+```
+
+### Example
+
+```
+Y({
+  db: {
+    name: 'indexeddb'
+  },
+  connector: {
+    name: 'websockets-client', // choose the websockets connector
+    // name: 'webrtc'
+    // name: 'xmpp'
+    room: 'Textarea-example-dev'
+  },
+  sourceDir: '/bower_components', // location of the y-* modules
+  share: {
+    textarea: 'Text' // y.share.textarea is of type Y.Text
+  }
+  // types: ['Richtext', 'Array'] // optional list of types you want to import
+}).then(function (y) {
+  // bind the textarea to a shared text element
+  y.share.textarea.bind(document.getElementById('textfield'))
+}
+```
