 Create a new bundle
 *******************
 
-Create your own bundle is not a trivial task.
-
-The easiest way to achieve this is seems to be : 
-
-1. Prepare a fresh installation of the chill project, in a new directory
-2. Create a new bundle in this project, in the src directory
-3. Initialize a git repository **at the root bundle**, and create your initial commit.
-4. Register the bundle with composer/packagist. If you do not plan to distribute your bundle with packagist, you may use a custom repository for achieve this [#f1]_
-5. Move to a development installation, made as described in the :ref:`installation-for-development` section, and add your new repository to the composer.json file
-6. Work as :ref:`usual <editing-code-and-commiting>`
