This is my GNU nano configuration. I set colors and auto-quote.
Run commad in your shell:
curl -Lo ~/.nanorc https://raw.githubusercontent.com/YuanPres/nanorc/master/.nanorc
OR
wget -O ~/.nanorc https://raw.githubusercontent.com/YuanPres/nanorc/master/.nanorc
OR
git clone https://github.com/YuanPres/nanorc.git ~/nano ; cp ~/nano/.nanorc ~/ ; rm -rf ~/nano
