+		  Use this script to checkout turris-build repository relative to branch on
+		  repo.turris.cz. It not only checkouts exact commit in turris-build
+		  repository, but it also modifies feeds.conf file so exactly same feeds are
+		  used as they were used to build files on server.
+
+		BRANCH argument is required and is target publish branch (Do not mix this
+		  with git branch of same name).
+		BOARD is optional argument used to specify different board. In default
+		  'omnia' is used. This is available because sometimes versions for boards
+		  are not in sync and can differ. It should be in most cases safe to use
+		  default but if you encounter problems you can try setting appropriate
+		  board.
+
+		Options:
+		  -h, --help  Print this help text
