+## Security
+
+This project attempts to take security seriously. Please note the following
+hardening notes applied by default.
+
+### Hardened `systemd` service configuration
+
+In principle, this service needs very little access to a host, and needs access
+to the internet. As a result, the default `systemd` service configuration
+aggressively restricts the capabilities of the binary to a minimum set of
+features, namely access to the internet and dependency to do so. If you believe
+more directives could be provided, please create a PR.
