1. Edit /boot/config.txt.

   $ sudo nano /boot/config.txt
   disable_overscan=1
   hdmi_force_hotplug=1
   hdmi_group=2
   hdmi_mode=48
   hdmi_drive=2
   config_hdmi_boost=4
   start_x=0
   gpu_mem=8
   dtparam=spi=off
   dtparam=i2c_arm=off
   max_usb_current=1 # maximum current for usb

2. Run raspi-config.

   $ sudo raspi-config

   Please select each option that you interested in to config.

   • Expand Filesystem.
   • Change User Password.
   • Boot Options: B1 Console.

1. Update packages index from official repository.

   $ sudo apt-get update

2. Upgrade installed packages.

   $ apt-get upgrade

1. List installed packages and save it to a file.

   $ dpkg-query --show -f '${Package}\n' > pkgs.list

1. Disable triggerhappy.

   $ sudo systemctl disable triggerhappy

2. Edit /etc/bash.bashrc

   $ sudo nano $HOME/.bashrc
   PS1="\[\033[01;32m\]\u@\h\[\033[00m\]:\W \[\033[01;34m\]\A \[\033[00m\]\`if [ \$? == 0 ]; then echo \:\); else echo '\[\033[0;31m\]:('; fi\`\[\033[00m\] "

3. Disable password authentication for SSH.
   • Generate authentication key in the machine which you want to login from, and copy the result to the Raspberry.

     $ ssh-keygen
     $ ssh-copy-id user@raspberry

   • Edit sshd_config and restart sshd.

     $ sudo nano /etc/ssh/sshd_config
     PasswordAuthentication no

     $ sudo systemctl restart ssh
