			Entry points
			------------

			Quick word about entry-points: it is a mechanism widely used in Invenio 3.

			Invenio is built on top of Flask, so it inherits its mechanisms: it is made of modules that you can add to get new features in your base installation.

			In order to extend Invenio, modules use entry-points. There are a lot of available entry-points, like:

			- bundles (to use CSS or JavaScript bundle)
			- models (to store data in the database)
			- ...

			The complete list of entry points in Invenio can be seen running ``invenio instance entrypoints``.

			Depending on how your module extends Invenio, it will be registered on one or several entry points. A module can also add new entry points, thus the bundles entry point comes from ``invenio_assets``, and its complete name is ``invenio_assets.bundles``.

			The entry-points used by your module are listed in the ``setup.py`` file.
