+
+
+Due to changes in Raspberry Pi OS, which is OS_NAME is based on,
+there is no longer a OS_NAME-wpa-supplicant.txt available.
+
+How do I setup a (new) network on my Pi ?
+-----------------------------------------
+
+As described in the original Raspberry Pi OS documentation.
+See https://www.raspberrypi.com/documentation/computers/configuration.html#setting-up-a-headless-raspberry-pi.
+
+
+Quote:
+    You will need to define a wpa_supplicant.conf file for your particular wireless network.
+    Put this file onto the boot folder of the SD card.
+    When the Raspberry Pi boots for the first time,
+    it will copy that file into the correct location in the Linux root file system
+    and use those settings to start up wireless networking.
+
+    The Raspberry Pi’s IP address will not be visible immediately after power on,
+    so this step is crucial to connect to it headlessly.
+    Depending on the OS and editor you are creating this on,
+    the file could have incorrect newlines or the wrong file extension,
+    so make sure you use an editor that accounts for this.
+    Linux expects the line feed (LF) newline character.
+
+What does that all mean? What have I todo now?
+----------------------------------------------
+
+For short, get a proper text editor of your choice.
+Recommendations are Notepad++, VSCode, Atom or SublimeText.

+################################################################################
+
+!!!!! HEADS-UP WINDOWS USERS !!!!!
+----------------------------------
+
+Do not use Wordpad for editing this file, it will mangle it and your
+configuration won't work. Use a proper text editor instead.
+
+!!!!! HEADS-UP MACOSX USERS !!!!!
+---------------------------------
+
+If you use Textedit to edit this file make sure to use "plain text format"
+and "disable smart quotes" in "Textedit > Preferences", otherwise Textedit
+will use none-compatible characters and your network configuration won't work!
+
+
+1.) Open your choosen Texteditor and create a new file called
+
+    wpa_supplicant.conf
+
+2.) Create a some basic configuration. This has to be in place!
+
+    ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
+    country=<Insert 2 letter ISO 3166-1 country code here>
+    update_config=1
+
+Valid Country Codes are:
+
+    GB (United Kingdom)
+    FR (France)
+    DE (Germany)
+    US (United States)
+    SE (Sweden)
+
+For a full list, please visit https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2
+
+2.1) If you plan to use multiple WiFi networks, also add
+
+    ap_scan=1
+
+to the mentioned basic configuration.
+
+
+3.) Setup your "network" block.
+
+For detailed information, please consult:
+https://linux.die.net/man/5/wpa_supplicant.conf
+or
+https://wiki.debian.org/WiFi/HowToUse#wpa_supplicant
+or
+https://man.archlinux.org/man/wpa_supplicant.conf.5
+
+Examples:
+
+Open or unsecured WiFi network:
+-------------------------------
+
+# Open/unsecured
+network={
+  scan_ssid=1 # Used to find hidden SSID's
+  ssid="put SSID here"
+  key_mgmt=NONE
+}
+
+-------------------------------
+
+
+WEP "secured" network:
+-------------------------------
+
+NOTE:
+
+    WEP can be cracked within minutes. If your network is still relying on this
+    encryption scheme you should seriously consider to update your network ASAP.
+
+network={
+  ssid="put SSID here"
+  key_mgmt=NONE
+  wep_key0="put password here"
+  wep_tx_keyidx=0
+}
+--------------------------------
+
+
+WPA2 Personal secured network:
+(Please don't use WPA secured networks, WPA isn't secure anymore)
+--------------------------------
+
+# WPA/WPA2 secured
+network={
+        scan_ssid=1 # Used to find hidden SSID's
+        ssid="<Name of your wireless LAN>"
+        psk="<Password for your wireless LAN>"
+        proto=RSN
+        key_mgmt=WPA-PSK
+        pairwise=CCMP
+        auth_alg=OPEN
+}
+--------------------------------
+
+For the WPA2 Enterprise setup, please use your google-foo.
+This is an advanced topic!
+
+4.) Put that file on to the "/boot" partition,
+this partition is FAT32 formatted and should be visible if you plug the SD Card into your computer.
+
+If you created a file while the Pi was running, copy that file to boot.
+Assuming you created the file in your users "home" directory use
+
+    sudo cp -v wpa_supplicant.conf /boot/
+
+5.) Almost done... Please reboot the pi and wait for it to connect.
+
+NOTE:
+
+Attach a screen and watch the console output to get its IP or
+consult your Router setup page to grab that information.
+
+You could also try to reach it by its hostname.
+
+    http://<yourpisname>.local
+
+If you didnt change the hostname during initial flash, you could use
+
+    http://OS_NAME.local
+
+6.) Enjoy OS_NAME :)
