if u want to install on EMMC assuming you have partioned it already.

just type this:
mke2fs -L NITDroid -j -m0 /dev/mmcblk0p5

apt-get install nitdroid-installer

mkdir -p /and
mount -o noatime,rw /dev/mmcblk0p5 /and
cd /home/user/MyDocs
wget http://downloads.nitdroid.com/nitins...-0.0.9.tar.bz2
rm -rf /and/*
bzcat NITDroid-0.0.9.tar.bz2 | tar xvC /and

wget http://downloads.nitdroid.com/Jay-c/...nal1_armel.deb
dpkg -i nitdroid*deb

cd /
umount /and
