-===================
+# Graph-Visualization
 
 This project is about 3D graph visualization with WebGL. The aim of this project is to evaluate the possibilities of graph drawing in WebGL.
 
 This project uses Three.js for drawing and currently supports a force directed layout.

+## Contribution
+
+This project uses [Grunt](http://gruntjs.com/) to run several tasks in development. You should have `npm` and `grunt` installed. To install `grunt` run
+
+    npm install -g grunt-cli
+
+And to install all dependencies run
+
+    npm install
