Just like champion.gnuroot.wheezy, but for x86 devices.

Allows you to create and launch a Debian Wheezy rootfs without rooting your device when used along with GNURoot (champion.gnuroot).

Primarily, I install packages with apt-get (http://linux.die.net/man/8/apt-get) and I suggest you do the same). To use apt-get you will need to click the "Launch as Fake Root" checkbox. A good place to start is to do:
apt-get update
apt-get upgrade
Then start working. If you find out that something you need is not installed, just apt-get it. To install less, do this:
apt-get install less
That is pretty obvious, but sometimes it is not. You can use a search engine (like google to help you out). For example, I found out to install R, I should do this:
apt-get install r-base
You can also search for packages using
apt-cache search some_keyword
A very popular package to add right away is this one:
apt-get install build-essential
This gets you setup to run the make and compile steps of many SW projects.
