+
+## Installation
+
+1. Copy arpcheck to `/usr/local/bin`
+
+2. Create `/var/log/arpcheck directory` (or directory to match log directory in conf file)

+   You may make as many individual configuartion files as you want.
+
+4. Create `/etc/arpcheck directory`
+
+5. Copy arpcheck config files you made to `/etc/arpcheck` directory
+
+6. Copy `arpcheck@.service` file to `\etc\systemd\system`
+
+7. Enable service: `systemctl enable arpcheck@<name_of_config_file>.service`
+
+8. Start service: `systemctl start arpcheck@<name_of_config_file>.service`
