[Interest] Doubts on ICS page

I am a beginner in this Yocto stuff.

My objective: Angstrom operating system with built in Qt5 libraries on
Beaglebone Black.
My source:

I was expecting when I do "bitbake" (the final step), I will get a image
file which I will copy to a memory card and flash the on board eMMC of
Beaglebone black with it.
But I dont see an image. :(


1. Where is my image ?

2. Why are we adding line for qt5 even though it is already there in the
conf/bblayers.conf file.

diff --git a/conf/bblayers.conf b/conf/bblayers.conf
index 57606f6..ccc8ab2 100644
--- a/conf/bblayers.conf

   ${TOPDIR}/sources/meta-ros \

   ${TOPDIR}/sources/meta-beagleboard/meta-beagleboard-extras \

3. Why are we cloning qt5 metadata since one is already there in the
setup-scripts/sources directory?

4. How is the bblayer.conf file interpreted by yocto during bitbake?
(please explain in detail, i am naive)

5. What all should I edit if I wanna add a new metadata to the build?

Looking forward for reply.

Sincere Regards,
