Important Help please

Hello

So I have a note 2 and I am on DN4 rom based on 4.4.4 android version

I want to upgrade to blisspop 5.1.1 rom

After I download the rom and the Gapps .. I went to recovery (TWRP 2.8.6.0) and made A cache and dalvic cache

and when I tried to flash the rom .. I had an error message saying no MD5 file found and installation failed

apparently I am missing something to do before upgrading from 4.4.4 to 5.1.1 but I don't know what is it

So help me please

Thanks in advance
