# Deploying from source
The minimum openstack-origin-git config required to deploy from source is:
openstack-origin-git:
"repositories:
- {name: requirements,
repository: 'git://git.openstack.org/openstack/requirements',
branch: stable/juno}
- {name: neutron,
repository: 'git://git.openstack.org/openstack/neutron',
branch: stable/juno}"
Note that there are only two 'name' values the charm knows about: 'requirements'
and 'neutron'. These repositories must correspond to these 'name' values.
Additionally, the requirements repository must be specified first and the
neutron repository must be specified last. All other repostories are installed
in the order in which they are specified.
The following is a full list of current tip repos (may not be up-to-date):
