+    # This workflow relies on:
+    #   - A specific hardware (benchmark-pool-1) in order to have a consistent
+    #     and comparable results against multiple builds.
+    #
+    #   - Some persistent data to reduce the time needed to checkout
+    #     mozilla-central.
+    #
+    # To setup such host multiple things should be considered.
+    #
+    # In terms of security, the code which is executed on this hardware should
+    # not be trusted. As such, the Github Action jobs should run on a dedicated
+    # computer which is either isolated or containerized. Do not run this setup
+    # on a non-dedicated computer!
+    #
+    # It is best to create a dedicated user.
+    #   $ mkdir /var/github-action-runner
+    #   $ useradd -d /var/github-action-runner github-action-user
+    #
+    # Make sure this newly added user has no sudo capabilities.
+    #
+    # A checkout of Gecko should be present under /var/github-action-runner. The
+    # dependencies for building Gecko should as well be installed with `mach
+    # bootstrap`, which can be done using another user with sudo capabilities,
+    # and changing the HOME environment variable to match the github-action-user
+    # home.
+    #
+    # The file /var/github-action-runner/.profile contains:
+    #
+    #    export PATH="$HOME/.cargo/bin:$PATH"
+    #    export PATH="/var/github-action-runner/.mozbuild/git-cinnabar:$PATH"
+    #
+    # Which is used to add cargo in the path, as well as git-cinnabar, to keep
+    # the gecko clone up to date.
+    #
+    # To add this computer to the benchmark pool, follow the instruction
+    # provided by github, after clicking "Add runner" on this page:
