## Installing

There are two methods for downloading and installing the Standard Edition for Twig:

* [Download a pre-built project](#download-a-pre-built-package)
* [Use Composer to create a project](#use-composer-to-create-a-project)

### Download a pre-built project

The fastest way to get started with the Standard Edition for Twig is to [download the pre-built version](https://github.com/pattern-lab/edition-php-twig-standard/releases) from the [releases page](https://github.com/pattern-lab/edition-php-twig-standard/releases). The pre-built project comes with the [Base StarterKit for Twig](https://github.com/pattern-lab/starterkit-twig-base) installed by default.

**Please note:** Pattern Lab uses [Composer](https://getcomposer.org/) to manage project dependencies. To upgrade the Standard Edition for Twig or to install plug-ins you'll need to [install Composer](https://getcomposer.org/doc/00-intro.md#installation-linux-unix-osx). We recommend that you [install it globally](https://getcomposer.org/doc/00-intro.md#globally).

### Use Composer to create a project

Pattern Lab uses [Composer](https://getcomposer.org/) to manage project dependencies.

#### 1. Install Composer 

Please follow the directions for [installing Composer](https://getcomposer.org/doc/00-intro.md#installation-linux-unix-osx) on the Composer website. We recommend you [install it globally](https://getcomposer.org/doc/00-intro.md#globally).

#### 2. Install the Standard Edition for Twig

Use Composer's [`create-project` command](https://getcomposer.org/doc/03-cli.md#create-project) to install the Standard Edition for Twig into a location of your choosing. In Terminal type:

    cd install/location/
    composer create-project pattern-lab/edition-twig-standard your-project-name && cd $_

This will install the Standard Edition for Twig into a directory called `your-project-name` in `install/location/`. During the set-up process you will be asked to install an appropriate StarterKit. You will be automatically dropped into the project directory after the process is finished.
