+# Running metrics.sh as a systemd service on Linux
+
+Run the following commands as root:
+
+```sh
+# Install metrics.sh at /opt/metrics.sh
+$ mkdir /opt; cd /opt
+$ git clone https://github.com/pstadler/metrics.sh.git
+$ cd metrics.sh
+# Install the service
+$ cp -p $PWD/systemd/metrics.sh.service /etc/systemd/system/metrics.sh.service
+$ chmod 664 /etc/systemd/system/metrics.sh.service
+# Create a config file
+$ mkdir /etc/metrics.sh && chmod 600 /etc/metrics.sh
+$ ./metrics.sh -C > /etc/metrics.sh/metrics.ini
+# At this point you should edit your config file at
+# /etc/metrics.sh/metrics.ini
+
+# Reload systemd daemon
+$ systemctl daemon-reload
+
+# Start service
+$ systemctl start metrics.sh.service
+
+# If run with the default configuration where reporter is 'stdout', metrics
+# will be written to /var/log/metrics.sh.log. Be aware that this file will
+# grow fast.
+$ tail -f /var/log/metrics.sh.log
+
+# Stop service
+$ systemctl stop metrics.sh.service
+
+# Check service status
+$ systemctl status metrics.sh.service
+
+# Automatically start service when booting and stop when shutting down
+$ systemctl enable metrics.sh.service
+
+# Disable automatic starting/stopping
+$ systemctl disable metrics.sh.service
+```
