```sh
make
sudo make install
remote_plot
```

usage
```sh
# use default ssh destination
remote_plot
# use another ssh destination
remote_plot -d 10.0.0.7
# run locally
remote_plot -l
```

Infrastructure configs not included in the repo, not included exactally, or maybe inclulded in other url:
- raspberry pi
    - file in ~/.config/labwc/autostart dir autostart remote_plot locally
        - <https://wiki.archlinux.org/title/Labwc#Autostart>
- server and laptop:
    - wireguard related configs
        - files in /etc/wireguard, see below
        - files in /etc/NetworkManager/system-connections
    - /etc/nftables.conf nftables firewall configs
