 *** Initial Startup
 **** Physical Setup

+***** Login via SSH
+Assuming your router supports finding your Raspberry Pi via its
+default hostname of `raspberypi`, log into the pi via Wi-Fi using the
+following command:
+
+: $ ssh pi@raspberrypi
+
+Otherwise, you may have to identify the raspbery pi's IP address via
+your network router's administration console and login via a command
+resembling this:
+
+: $ ssh pi@192.168.x.x
+
+If you had previously set up a different raspberry pi that also used
+the same hostname ~raspberrypi~ or the same IP address (ex:
+~192.168.123.123~), you may have to inform your computer that this is a
+different device. You may do so using these commands:
+
+: $ ssh-keygen -f ~/.ssh/known_hosts -R "raspberrypi"
+: $ ssh-keygen -R 192.168.123.123
+
 ***** Add SSH public key
 If the use has an SSH public key, it may be added as a line in
 ~~/.ssh/authorized_keys~.
 
+Add the ~~/.ssh~ directory if it doesn't already exist.

+***** Disable Bluetooth
+In order to reduce power consumed by bluetooth transmissions,
+bluetooth functionality should be disabled (see [[https://di-marco.net/blog/it/2020-04-18-tips-disabling_bluetooth_on_raspberry_pi/][link]]).
+
+Modify the ~/boot/config.txt~ file (the Pi's equivalent to BIOS

+
+#+BEGIN_EXAMPLE

+The ~hciuart~ service is associated with bluetooth functionality via
+UART which may conflict with location and time data provided via

+
+***** Disable login console via serial port
+Some ~ninfacyzga~ functions (location and time) require data transfer
+via ~/dev/ttyAMA0~. In order to prevent serial login programs from
+interfering with such functions, it is necessary to disable them.
+
+Run the following commands to disable login via ~ttyAMA0~:
+
+#+BEGIN_EXAMPLE
+$ sudo systemctl stop serial-getty@ttyAMA0.service
+$ sudo systemctl disable serial-getty@ttyAMA0.service
+$ sudo systemctl disable hciuart
