[Composer (a dependancy manager for PHP)](http://getcomposer.org) is the preferred way to install SilverStripe and ensure you get the correct set of files for your project.
Composer uses your MAMP PHP executable to run and also requires [git](http://git-scm.com) (so it can automatically download the required files from GitHub).
2. Add the following line (adjusting the version number of PHP to your installation of MAMP): `alias phpmamp='/Applications/MAMP/bin/php/php5.4.10/bin/php'`.
4. This will create an alias, `phpmamp`, allowing you to use the MAMP installation of PHP. Please take note of the PHP version, in this case 5.4.10, as with different versions of MAMP this may be different. Check your installation and see what version you have, and replace the number accordingly (this was written with MAMP version 2.1.2).
5. With that setup, we are ready to install `composer`. This is a two step process if we would like this to be installed globally (only do the first step if you would like `composer` installed to the local working directory only).
- First, run the following command in the terminal: `curl -sS https://getcomposer.org/installer | phpmamp`
We are using `phpmamp` so that we correctly use the MAMP installation of PHP from above.
- Second, if you want to make composer available globally, we need to move the file to '/usr/local/bin/composer'. To do this, run the following command:
`sudo mv composer.phar /usr/local/bin/composer`
Terminal will ask you for your root password, after entering it and pressing the 'return' (or enter) key, you'll have a working global installation of composer on your mac that uses MAMP.
6. You can verify your installation worked by typing the following command:
`composer`
It'll show you the current version and a list of commands you can use.
7. Run the following command to get a fresh copy of SilverStripe via composer:
8. You can now [use composer](http://doc.silverstripe.org/framework/en/getting_started/composer/) to manage future SilverStripe updates and adding modules with a few easy commands.
### Package Download
