4. Use an ethernet cable to connect the Pi to your main computer
* Your computer should immediately start acting as a “wired hotspot” now and provide IP address and internet access to the Pi.
5. You can now `ssh jakob@poolpaypi.local` on your main computer and it shoud Just Work™.
#### Pi as a WiFi hotspot
1. Plug in a WiFi stick (on the Raspberry Pi 3 Model V1.2, I didn't get the internal WiFi to work as a hotspot, however, that seems to be an issue that only I with my specific Pi have)
2. Create a network manager configuration in `/etc/NetworkManager/system-connection/PoolPayPi.nmconnection`, get the following information ...
* The `interface-name` for the stick (`wlan1` if the Pi has built-in wifi, `wlan0` if it hasn't)
* A secure password (Pre-Shared Key, `psk`)
... and insert it into this ready made template, which you then save:
```ini
[connection]
id=PoolPayPi
uuid=a58d13bb-4d84-4b20-8bea-7b061c73ed0c

<summary>Further information on hotspots</summary>
* You can create a hotspot (which will create more or less the same config as seen above using):
* If you want the hotspot to start on boot, you need to add `autoconnect=true` to the config file (which you can, btw, also do using some `nmcli` command)
* If you use both the WiFi hotspot and the shared ethernet connection (which is easily possible), [one of the connections needs its own IP range](https://askubuntu.com/questions/844913/how-to-control-ip-ranges-of-network-managers-hotspots), otherwise, they will collide.
