 jIO is a promised-based JavaScript library that offers connectors to many storages (Dropbox, webdav, IndexedDB, GDrive, ...) using a single API. jIO supports offline use, replication, encryption and synchronization as well as querying of stored documents and attachments allowing to build complex client-side centric web applications.

 You can run tests after installing and building jIO by opening the */test/* folder
+
+## Build with rollup
+
+```
+$ npm install -g rollup

+
+## jIO for Node.js
+
+1. Install the package
+```sh
+$ npm install --save https://lab.nexedi.com/nexedi/jio.git
+```
+2. Import the library and create your first storage:
+```javascript
+const { jIO } = require('jio/dist/node/jio.js');
+const jio = jIO.createJIO({
+  type: 'memory'
+});
+```
