 # Software/Firmware
 Python code for operating the extension PCBs (e.g., GPIO pins, shift registers, ADC, and bus communication). This section is a work in progress (WIP), and example scripts will be added as development continues.
 
+# ======== WIP ========
+# Python scripting
+
+The pin assignment to the actual terminals are defined / mapped in
+`rpi-scripts\interface_board_pins.py` so it should be included in any custom script created to easily reference the terminal numbers printed onto the project housing in the code. See examples in `rpi-scripts\examples`
+TODO: make those files link to file but with text still the file path
+
+# Usage Raspberry-PI
+## Connectivity
+
+### Establish LAN Connection (ethernet)
+configure in command.txt in boot partition?
+### Establish WIFI Connection
+```bash
+s  nmcli device wifi connect <SSID> password <password>
+# replace <SSID> and <password> with actual wifi
+```
+
+### Connect via ssh
+```powershell
+ssh pi@192.168.1.100
+```
+
+### Connect via rdp
+Open mstsc from windows start menu, and enter ip, user root and password.
+Or use powershell:
+```powershell
+mstsc /v:192.168.1.100:3389
+```
+Note: currently only user `root` works (using user pi results in blackscreen)
+
+### Mount filesystem in windows
+You can mount /home/pi folder in windows natively using samba
+Run in powershell to mount it as network device X (replace ip with the current ip of rpi)
+Find out ip with running `ip a` on the raspberry
+```powershell
+net use X: \\192.168.1.100\pi /user:pi
+```
+
+## Scripts
+
+### Autostart GUI
+```bash
+git/rpi-interface-board/rpi-scripts/gui% s cp gui-start.service /etc/systemd/system/
+```
+# ======== END WIP ========
