+###### 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 [installation-for-development` section, and add your new repository to the composer.json file
+6. Work as :ref:`usual ](editing-code-and-commiting.md)
