The script below downloads the 0.10.1 version appimage of nvim and places files where they need to be. Make sure you run this as root as most of the commands need to be elevated.

OUTFILE="nvim.0.10.1.appimage" &&
wget $NVIMURL -O $OUTFILE &&
chmod 755 $OUTFILE &&
./$OUTFILE --appimage-extract &&
chown -R root:root $OUTFILE squashfs-root &&
cp squashfs-root/usr/share/applications/nvim.desktop /usr/share/applications/nvim.desktop &&
cp squashfs-root/nvim.png /usr/share/icons/ &&
rm -rf squashfs-root &&
mkdir -p /usr/local/bin &&
