 Copying a already synced blockchain from another computer (for example your Laptop) can be a quick way to get the RaspiBlitz started or replacing a corrupted blockchain with a fresh one. Also that way you synced and verified the blockchain yourself and not trusting the RaspiBlitz Torrent downloads (dont trust, verify).
 
-One requirement is that the blockchain is from another bitcoin-core client with version greater or equal to 0.17.1 with transaction index switched on (`txindex=1` in the `bitcoin.conf`).
+One requirement is that the blockchain is from another bitcoin-core client with version greater or equal to 0.17.1.
 
 But we dont copy the data via USB to the device, because the HDD needs to be formatted in EXT4 and that is usually not read/writeable by Windows or Mac computers. So I will explain a way to copy the data through your local network. This should work from Windows, Mac, Linux and even from another already synced RaspiBlitz.

-If you have another computer available (laptop, desktop or another raspiblitz) that already runs a working blockchain (with txindex=1) you can use this option to copy it over to the RaspiBlitz. This will be done over the local network by SCP (SSH file transfere). Choose this option and follow the given instructions.

+The bitcoin core client (0.17.1 or higher) needs to be stopped while the data is copied to the HDD.
 
 The easiest way to get a "template" of such HDD is to setup a fresh RaspiBlitz (without channel and fundings) and then run the script `/home/admin/XXcleanHDD.sh` and manually delete all rest data from the HDD and just leave those folders.
