### Using systemd service file
To start Parity as a regular user using systemd init:
1. Copy ```parity/scripts/parity.service``` to your
systemd user directory (usually ```~/.config/systemd/user```).
2. To pass any argument to Parity, write a ```~/.parity/parity.conf``` file this way:
```ARGS="ARG1 ARG2 ARG3"```.
