 Now open your torrent client (e.g. qTorrent for OSX) and create a new torrent-file with the freshly renamed "torrent base directory" as source directory.

 #### Torrent Files Naming Schema
 
 The base torrent file should always have the following naming scheme:
-raspiblitz-[CHAINNETWORK][BASEITERATIONNUMBER]-[YEAR]-[MONTH]-[DAY]-base.torrent
+
+`raspiblitz-[CHAINNETWORK][BASEITERATIONNUMBER]-[YEAR]-[MONTH]-[DAY]-base.torrent`
 
 So for example the second version of the base torrent for litecoin created on 2018-10-31 would have this name: raspiblitz-litecoin2-2018-10-31-base.torrent
 
 The update torrentfile should always have the following naming schema:
-raspiblitz-[CHAINNETWORK][BASEITERATIONNUMBER]-[YEAR]-[MONTH]-[DAY]-update.torrent
+
+`raspiblitz-[CHAINNETWORK][BASEITERATIONNUMBER]-[YEAR]-[MONTH]-[DAY]-update.torrent`
 
 So for exmaple an update torrent created on 2018-12-24 for litecoin that is an update to the second base torrent version would have this name: raspiblitz-litecoin2-2018-12-24-update.torrent
