 OpenCascade nodejs extension for solid modeling.
 
-This nodejs extension provides *solid construction* to nodejs. 
+This nodejs extension provides _solid construction_ to nodejs.
 It provides a simple yet powerful javascript api to construct 3D geometry models.
 
 This project comes with a set of V8 wrappers around OpenCascade API and a sample web application.

 ### quick example
 
-
 ```javascript
-var occ = require('occ').occ
+var occ = require("node-occ").occ;
 
 // construct a box
-var box = occ.makeBox([0,0,0],[100,100,50])
+var box = occ.makeBox([0, 0, 0], [100, 100, 50]);
 
 // construct a cylinder
-var cyl = occ.makeCylinder([50,50,-10],[50,50,60],40)
+var cyl = occ.makeCylinder([50, 50, -10], [50, 50, 60], 40);
 
 // cut the box with cylinder
-box = occ.cut(box,cyl)
+box = occ.cut(box, cyl);
 
 // save result to a STEP file
-occ.writeSTEP("somefile.step",box)
-
+occ.writeSTEP("somefile.step", box);
 ```
