 50###Security Issues
 51
 52If you discover a security vulnerability in Express, please see [Security Policies and Procedures](Security.md).
 53
 54## Quick Start
 55
 56  The quickest way to get started with express is to utilize the executable [`express(1)`](https://github.com/expressjs/generator) to generate an application as shown below:
 57
 58  Install the executable. The executable's major version will match Express's:
 59
 60```bash
 61$ npm install -g express-generator@4
 62```
 63
 64  Create the app:
 65
 66```bash
 67$ express /tmp/foo && cd /tmp/foo
 68```
 69
 70  Install dependencies:
 71
 72```bash
 73$ npm install
 74```
 75
 76  Start the server:
 77
 78```bash
 79$ npm start
 80```
 81
 82## Philosophy
 83
 84  The Express philosophy is to provide small, robust tooling for HTTP servers, making
 85  it a great solution for single page applications, web sites, hybrids, or public
 86  HTTP APIs.
 87
 88  Express does not force you to use any specific ORM or template engine. With support for over
 89  14 template engines via [Consolidate.js](https://github.com/tj/consolidate.js),
 90  you can quickly craft your perfect framework.
 91
 92## Examples
 93
 94  To view the examples, clone the Express repo and install the dependencies:
 95
 96```bash
 97$ git clone git://github.com/expressjs/express.git --depth 1
 98$ cd express
 99$ npm install
100```
101
102  Then run whichever example you want:
103
104```bash
105$ node examples/content-negotiation
106```
107
108## Tests
109
110  To run the test suite, first install the dependencies, then run `npm test`:
111
112```bash
113$ npm install
114$ npm test
115```
