 ## building
 If you check out the code from git you first need to clone submodule cairo-jpeg:
-    git submodule init
-    git submodule update
-
+```
+git submodule init
+git submodule update
+```
 Makefile relies on pkg-config, if setup correctly simply running 'make'
 should build the application which can be run from the source directory,
 'make deb' builds a Debian package (to the parent directory)
 
 ## libusb & udev
 For access rights of the application to the USB device:
-
-    cp 77-flirone-lusb.rules /lib/udev/rules.d/
-    udevadm control --reload-rules
+```
+cp 77-flirone-lusb.rules /lib/udev/rules.d/
+udevadm control --reload-rules
+```
