+This is an NPM of the stable version of the Verovio JavaScript toolkit.
+
+Verovio is a fast, portable and lightweight library for engraving [Music Encoding Initiative (MEI)](http://www.music-encoding.org) music scores into SVG.
+
+See it running in the [MEI Viewer](http://www.verovio.org/mei-viewer.xhtml) and check out the [tutorial](http://www.verovio.org/tutorial.xhtml) for its web integration and for enabling user interaction.
+
+## Usage
+
+```javascript
+var verovio = require('verovio');
+
+var vrvToolkit = new verovio.toolkit();
+
+mei = fs.readFileSync("hello.mei");
+
+vrvToolkit.loadData(mei.toString());
+
+svg = vrvToolkit.renderPage(1, {});
+
+fs.writeFileSync("hello.svg", svg);
+```
+
+### Memory allocation
+
+The memory available for Verovio can be increased during import by passing a MB value to the `init` function.
+
+```javascript
+var verovio = require('verovio').init(512);
+```
+
+The value has to be less than 1024MB.
