+The "ci" folder consists of-
+
+build.sh --> builds rpm packages (if -p package option is  passed as "centos"
+or in default case) by calling build_rpm subfolder files ; builds debian
+packages (if -p package option is  passed as "ubuntu") by calling build_deb
+subfolder files; builds both debian and rpm packages (if -p package option is
+passed as "both").
+
+build_deb --> contains the files required to build debian backages for kernel
+and qemu, inside ubuntu docker.
+
+build_rpm --> contains the files required to build rpm backages for kernel and
+qemu, inside centos docker.
+
+envs --> contains the host and guest setup+configuration files.
