+# @file git-o-matic Configuration
+# @brief Starts service on Linux systems to monitor Git repositories
+# @description
+#     git-o-matic is a tool to monitor git repositories and automatically pull/push changes. Multiple repositories can be
+#     monitored by running multiple instances of `gitomatic`. This script supports SSH Key based authentication only.
+#
+#     If the `gitomatic` program is installed, this script creates and starts a Systemd service to monitor the repositories.
+#     The repositories are cloned if they are not available at the path.
+#
+#     ## Notes
+#     * The author name and email address for commits are the same as `.user.name` and `.user.email` (configured in the `home/.chezmoi.yaml.tmpl` file)
+#     * `gitomatic` automatically pushes and pulls changes. The script does not change this behavior
+#     * `gitomatic` checks for changes every minute. This setting is not changed by this script
+#     * The User's default SSH Key is used for authentication
+#
