 ## Prepare Blockchain Copy Station
 
+In the RaspiBlitz Github repo and also on every RaspiBlitz (since v1.3) you can find the script:
+`/home/admin/CCcopyStation.sh`
+
+This can be used to prepare and keep multiple HDDs in snyc with blockchain data in preparation of a workshop. You can start it directly on a RaspiBlitz and turn it into "Copy Station Mode" with executing on the command line:
+
+`sudo /home/admin/CCcopyStation.sh`
+
+*Beware that it will not run as a Lightning Node during that time (LND is stopped). And to reset it back into normal mode you need to stop the script with `CTLR+c` and the reboot with `sudo shutdown -r now`.*
+
+In "COpy Station Mode" the RaspiBlitz will just run the bitcoind (so it needs network connection), copy fresh blockchain data over to a template folder on the HDD called `/mnt/hdd/templateHDD` and from there syncs it to further HDDs that get connected to it.
+
+If you run it in a setup lke on this photo with an extra powered USB hub, you can connect up to 10 HDDs at once to be synced with an almost up-to-date blockchain.
+
+
 At the moment the "Blockchain Copy Station" is just a computer (laptop - not a RaspberryPi) having a image of a "template" HDD (see above) and you can attach (with a USB3.0 Hub) multiple fresh HHDs to it and start writing in the template image to that.
 
 To update the "template" HDD for the next workshop use it for a fresh clean RaspiBllitz setup just days before, sync the blockchain to 100% and repeat the process above.
