+# Create Projects
+
+You can use Composer to create new projects from an existing package.
+There are several applications for this:
+
+1. You can deploy application packages.
+2. You can check out any package and start developing on patches for example.
+3. Projects with multiple developers can use this feature to bootstrap the initial application for development.
+
+To create a new project using composer you can use the "create-project" command.
+Pass it a package name, and the directory to create the project in. You can also
+provide a version as third argument, otherwise the latest version is used.
+
+The directory is not allowed to exist, it will be created during installation.
+
+    php composer.phar create-project doctrine/orm path 2.2.0
+
+By default the command checks for the packages on packagist.org. To change this behavior
+you can use the --repository-url parameter and either point it to an HTTP url
+for your own packagist repository or to a packages.json file.
+
+If you want to get a development version of the code directly checked out
+from version control you have to add the --prefer-source parameter.
