+You have to opened the LUKS partition here for the subsequent tasks. To open it, the script asks you type the passphrase.
 
+For the first distribution to install, I recommend you to type the passphrase to open the partition, because
+you might create the partition and encrypted it this time. The encryption was done with your passphrase you set to the
+PASSPHRASE variable. So, this is the last chance whether you set the passphrase correctly or not. 
+```bash
 # Open the created crypt partition. To be sure, input the passphrase manually
 cryptsetup open  "${DEV}${CRYPTPARTITION}" ${CRYPTPARTNAME}
 ```
+For the second, third, ... distribution to install, I recommend you to feed the passphrase from PASSPHRASE 
+variable automatically. The partition was encrypted in past. So, the this is the chance to check whether 
+the passphrase in the PASSPHRASE variable is correct or not.
+```bash
+# Open the created crypt partition. To be sure, input the passphrase manually
+printf %s "${PASSPHRASE}" | cryptsetup open -d - "${DEV}${CRYPTPARTITION}" ${CRYPTPARTNAME}

 Now, we are at critical phase. To avoid system asks passphrase twice, we have to embed the key inside ramfs initial image.
