# To all DEV around the world via Mansi :)                                    #
#                                                                             #
# 1.) use the "bash"                                                          #
# chsh -s /bin/bash `whoami`                                                  #
#                                                                             #
# 2.) delete old files                                                        #
# rm -r out                                                                   #

# 3.) now you can build my kernel                                             #
# ./build.sh                                                                  #
#                                                                             #
# Have fun and update me if something nice can be added to my source.         #
