+# Dockerfile to setup a new runner for CI service.
+# This file has all dependencies for running the following service(s):
+#   - gen_optimized.py
+#
+# System expectation:
+#   No Address Randomization (for deterministic instruction count):
+#       $> echo 0 > /proc/sys/kernel/randomize_va_space
+#   Userland Perf:
+#       $> echo -1 > /proc/sys/kernel/perf_event_paranoid
+#
+# Build Command:
+#   $> echo "${GITHUB_TOKEN}" | docker buildx build --secret id=github_token,src=/dev/stdin -t github-runner .
+#
+# Run Command:
+#   $> docker run --cap-add PERFMON -d --network=host --name github-runner github-runner
+#
+# To setup the system to maintain the runner/requirements on boot:
+#   1) Update container to always restart:
+#       $> docker update --restart=always <Container ID>
+#   2) Add system requirements to /etc/sysctl.conf:
+#       $> echo "kernel.perf_event_paranoid = -1" >> /etc/sysctl.conf
+#       $> echo "kernel.randomize_va_space = 0" >> /etc/sysctl.conf
