+
+Simple web service to convert 3D models from COLLADA to glTF using COLLADA2GLTF.
+
+[![Build Status](https://travis-ci.org/AnalyticalGraphicsInc/collada2gltf-web-service.svg?branch=master)](https://travis-ci.org/AnalyticalGraphicsInc/collada2gltf-web-service)
+
+## Overview
+
+This is a code sample that can serve as a starting point for a Node.js web service that converts COLLADA models to
+glTF.  This version just converts a .dae file to a .gltf with embedded geometry, animations, skins, and shaders.  It does not handle textures.
+
+## Install
+
+Install [Node.js](http://nodejs.org/), then run:
+```
+npm install collada2gltf-web-service
+```
+
+## Usage
+
+Start server using [nodemon](http://nodemon.io/) so it is automatically restarted when the code changes:
+```
+npm start
+```
+
+Invoke the web service by issuing an HTTP request and providing the COLLADA model with POST:
+```
+curl -X POST -H "Content-Type:text/plain" -d @test/data/box.dae localhost:3000/convert
+```
+
+A few settings can be changed by modifying [config.json](config.json).  This is loaded using [nconf](https://www.npmjs.com/package/nconf) so environment variables and command-line arguments can override this.
+
+## Tests and JSHint
+
+Run the tests:
+```
+npm test
+```
+
+Run JSHint:
+```
+npm jshint
+```
