 ============
 
-Application for SpringRoll projects
+SpringRollStudio is an native application (build with [nw-init](https://github.com/CloudKidStudio/nw-init) and designed to provide graphic user interfaces for building and managing [SpringRoll](https://github.com/SpringRoll/SpringRoll) projects.
+
+**Features**
+* Manage a captions library
+* Remote debugging over a network
+* Run Grunt tasks for SpringRoll projects
+* Scaffold a new project with support for custom templates
+
+## Dependencies
+
+In order to build SpringRollStudio, there are some external global dependencies that are required.
+
+### grunt
+
+Grunt is required to build. See the [getting started guide](http://gruntjs.com/getting-started).
+
+```bash
+npm install -g grunt-cli
+```
+
+### makensis
+
+[makensis](http://nsis.sourceforge.net/Main_Page) is required to create the Windows setup executable. Can be installed with [brew](http://brew.sh/):
+
+```bash

+## Building
+
+The Grunt project is an extension of the [grunt-game-builder](https://github.com/CloudKidStudio/grunt-game-builder) and all those grunt tasks can be used on your app. In addition, there are several Grunt tasks that are specific and useful to building SpringRollStudio:
+
+Task | Description

+**app** | Builds a release version of the node-webkit app
+**app-debug** | Builds a debug version of the node-webkit app
+**package** | Create the OSX and Windows installers
+**open** | Open the OSX application
+
+### Examples
+
+Build SpringRollStudio in debug mode and run:
+
+```bash
+grunt app-debug open
+```
+
+Build SpringRollStudio and package to installers:
+
+```bash
+grunt app package
+```
