# Search engines are welcome. AI training crawlers are not.
# This file is one of three places that reservation is stated; the others are
# the LICENSE in our repository (Sec. 5) and https://qcoretech.com/legal.html#terms.

# Content on this site is proprietary (see LICENSE). QuantumCore expressly

# fine-tune, or evaluate a machine-learning model requires a written license.
#
# Note honestly: robots.txt is voluntary. It establishes our reservation on the
# record and stops compliant crawlers; it does not stop a bad actor. The
# enforceable layer is the LICENSE and the Terms of Use, not this file.
