 The first configuration file that needs to be set up is the Hammer environment configuration file ``env.yml``. In this file you need to set the paths to the EDA tools and license servers you will be using. You do not have to fill all the fields in this configuration file, you only need to fill in the paths for the tools that you will be using.
 If you are working within a shared server farm environment with an LSF cluster setup (for example, the Berkeley Wireless Research Center), please note the additional possible environment configuration listed in the :ref:`VLSI/Basic-Flow:Advanced Environment Setup` segment of this documentation page.

+Hammer relies on YAML-based configuration files. While these configuration can be consolidated within a single files (as is the case in the ASAP7 tutorial :ref:`tutorial` and the ``sky130``
 OpenRoad example), the generally suggested way to work with an arbitrary process technology or tools plugins would be to use three configuration files, matching the three Hammer concerns - tools, tech, and design.
 The ``vlsi`` directory includes three such example configuration files matching the three concerns: ``example-tools.yml``, ``example-tech.yml``, and ``example-design.yml``.
