xv6 setup on Windows machines via WSL
-------------------------------------

1. Install WSL-2 by following the steps listed here : https://learn.microsoft.com/en-us/windows/wsl/install
  1.1 If it is a fresh install, it will install Ubuntu 24.04.1 
  1.2 If not then please install Ubuntu 24.04.1

2. Now open up wsl-terminal 
3. Execute `sudo apt-get update`
4. Execute `sudo apt install -y make` to install make
5. Execute `sudo apt install -y gcc-11`
  5.1 xv-6 requires gcc-11 to compile flawlessly
  5.2 Execute `sudo ln -s /usr/bin/gcc-11 /usr/bin/gcc` so that it can find `gcc`
6. Execute `sudo apt install -y qemu-system-i386`
7. Execute `curl https://www.cse.iitb.ac.in/~puru/courses/xv6-public.tar.gz --output xv6.tar.gz` to get the xv6 source
8. Execute `tar -xvzf xv6.tar.gz` to uncompress the source. It will be uncompressed to directory named `xv6-public`
9. Navigate to the xv-public directory by `cd xv6-public`
10. Execute `make qemu-nox` or `make qemu`
11. Now after a successful build a new terminal would be visibile, running xv6.
12. Execute `ls` to display the currently available files.
13. Execute `echo "helloworld! > hw.txt`
14. Execute `cat hw.txt`
15. Execute `wc hw.txt`
