+# This script provisions a GitHub Actions runner on a Rocky or CentOS system.
+# It performs the following steps:
+# 1. Checks the operating system from /etc/os-release.
+# 2. Verifies if the operating system is either Rocky or CentOS.
+# 3. Checks if an actions-runner process is already running for the current user.
+# 4. Copies the actions-runner tar file from a specified directory to the home directory.
+# 5. Extracts the tar file and starts the actions-runner in the background.
+#
+# The actions-runner tar file contains the necessary binaries and scripts to run
