          KCMA is an open-source CAD application for creating accurate 3D models
          for use in manufacturing. It is built on top of the KittyCAD API.
          KittyCAD is the first software infrastructure company built
          specifically for the needs of the manufacturing industry. With KCMA we
          are showing how the KittyCAD API can be used to build entirely new
          kinds of software for manufacturing.
        </p>
        <p className="py-4">
          KCMA is currently in development. If you would like to be notified
          when KCMA is ready for production, please sign up for our mailing list
