 * The :atc-file:`infrastructure/ansible/sample.lab/inventory` directory is where it's recommended for your provisioning layer to drop a valid Ansible inventory file describing what was allocated.  When using Ansible, it's important to point the inventory source to this directory so that it will merge all available inventory files together for you.
 * The :atc-file:`infrastructure/ansible/sample.lab/out/ssl` directory is generated with the first run of the lab and holds your local copy of the lab SSL data.  The out directory is also handy for holding temporary data from the provisioning or steady-state layers to help triage failures.
