# Project Setup
This document describes the necessary steps to setup a `bpmn-js` development environment.
## TLDR;
On Linux/Unix? [git](http://git-scm.com/), [NodeJS](nodejs.org) and [npm](https://www.npmjs.org/doc/cli/npm.html) ready? Check out the small setup script below.
## Manual Steps
Make sure you have [git](http://git-scm.com/), [NodeJS](nodejs.org) and [npm](https://www.npmjs.org/doc/cli/npm.html) installed before you continue.
### Get Project + Dependencies
The following projects from the [bpmn-io](https://github.com/bpmn-io) project on GitHub
* [bpmn-js](https://github.com/bpmn-io/bpmn-js)
* [diagram-js](https://github.com/bpmn-io/bpmn-js)
* [bpmn-moddle](https://github.com/bpmn-io/bpmn-moddle)
* [moddle](https://github.com/bpmn-io/bpmn-js)
* [moddle-xml](https://github.com/bpmn-io/bpmn-js)
and clone them into a common directory via
```
git clone git@github.com:bpmn-io/PROJECT_NAME.git
```
### Link Projects
[Link dependent projects](http://blog.nodejs.org/2011/04/06/npm-1-0-link/) between each other to pick up changes immediately.
```

```
#### On Linux
Use [npm-link](https://www.npmjs.org/doc/link.html) or `ln -s <target> <link>`.
#### On Windows
Use `mklink /d <link> <target>` [(docs)](http://technet.microsoft.com/en-us/library/cc753194.aspx).
### Install Dependencies
Execute `npm install` on each of the projects to grab their dependencies.
### Verify Things are O.K.
Execute `grunt` on any of the projects. Things should be nice.
## Setup via Script
The whole setup can be automated through the following script.
```bash
#!/bin/bash
base=`pwd`
echo cloning repositories
git clone git@github.com:bpmn-io/diagram-js.git > /dev/null
git clone git@github.com:bpmn-io/diagram-js-direct-editing.git > /dev/null
git clone git@github.com:bpmn-io/moddle.git > /dev/null
git clone git@github.com:bpmn-io/moddle-xml.git > /dev/null
git clone git@github.com:bpmn-io/bpmn-js.git > /dev/null
git clone git@github.com:bpmn-io/bpmn-moddle.git > /dev/null
git clone git@github.com:bpmn-io/ids.git > /dev/null
echo done.
