 When you come across documentation that states to run Composer as `php composer.phar install`, you can substitute that with:

 ### How to Define and Install Dependencies
 
-Composer keeps track of your project's dependencies in a file called `composer.json`. You can manage it by hand if you like, or use Composer itself. The `php composer.phar require` command adds a project dependency and if you don't have a `composer.json` file, one will be created. Here's an example that adds [Twig][2] as a dependency of your project. Run it in your project's root directory where you've downloaded `composer.phar`:

-Alternatively the `php composer.phar init` command will guide you through creating a full `composer.json` file for your project. Either way, once you've created your `composer.json` file you can tell Composer to download and install your dependencies into the `vendors/` directory. This also applies to projects you've downloaded that already provide a `composer.json` file:

 This is most useful when you define your version requirements flexibly. For instance a version requirement of ~1.8  means "anything newer than 1.8.0, but less than 2.0.x-dev". You can also use the `*` wildcard as in `1.8.*`. Now Composer's `php composer.phar update` command will upgrade all your dependencies to the newest version that fits the restrictions you define.

 ### Checking your dependencies for security issues
 
-The [Security Advisories Checker][3] is a web service and a command-line tool, both will examine your `composer.lock` file and tell you if you need to update any of your dependencies.
