I installed Koha on my linux system successfully,
while studying the demo ( on http://koha.liblime.com) and my local installation i found that in catalogue while adding the empty biblio there are many more and additional fields in the Demo while lesser in my local installation.
I also checked the version both are same (i installed koha2.2.5 and the about of demo also saying same).
So this make me little confused, since i am new to the koha and also i am form the open source development and not
have library management experience as such.
So please anybody having any inforamtion regarding this kindly help.
Also i searched for the properly documented (rather easy step-by-step) manuals  for how to use  and administer koha, 
but I am sorry i could not get that useful for me, so please also help in this regard.

Thank you,
