You can also setup a ``requirements.yml`` file to install multiple collections in one command. This file is a YAML file in the format:

.. code-block:: yaml+jinja

   ---
   collections:
   # With just the collection name
   - my_namespace.my_collection

   # With the collection name, version, and source options
   - name: my_namespace.my_other_collection
     version: 'version range identifiers (default: ``*``)'
     source: 'The Galaxy URL to pull the collection from (default: ``--api-server`` from cmdline)'

The ``version`` key can take in the same range identifier format documented above.

Roles can also be specified and placed under the ``roles`` key. The values follow the same format as a requirements
file used in older Ansible releases.

.. note::
    While both roles and collections can be specified in one requirements file, they need to be installed separately.
    The ``ansible-galaxy role install -r requirements.yml`` will only install roles and
    ``ansible-galaxy collection install -r requirements.yml -p ./`` will only install collections.
