Since you have installed Chromebrew in a directory other than '/usr/local',
you need to run these commands to complete your installation:
${RESET}"

  echo -e "${BLUE}
echo 'export CREW_PREFIX=${CREW_PREFIX}' >> ~/.bashrc
echo 'export PATH=\"\${CREW_PREFIX}/bin:\${CREW_PREFIX}/sbin:\${PATH}\"' >> ~/.bashrc

source ~/.bashrc

To set the default PAGER environment variable to use less:
echo \"export PAGER='less'\" >> ~/.bashrc && . ~/.bashrc

Alternatively, you could use most.  Why settle for less, right?
echo \"export PAGER='most'\" >> ~/.bashrc && . ~/.bashrc

Below are some text editor suggestions.

To install 'nano', execute:
crew install nano

Or, to get an updated version of 'vim', execute:
crew install vim

You may wish to set the EDITOR environment variable for an editor default.

For example, to set 'nano' as the default editor, execute:
echo \"export EDITOR='nano'\" >> ~/.bashrc && . ~/.bashrc

To set 'vim' as the default editor, execute:
echo \"export EDITOR='vim'\" >> ~/.bashrc && . ~/.bashrc
${RESET}"
echo -e "${GREEN}Chromebrew installed successfully and package lists updated.${RESET}"
