@@ -6,20 +6,21 @@ The model sets a simple state machine, a non-deterministic environment and
 a set of 4 LTL properties are verified.
 
 The LTL properties are:
-1.  (x == ENABLE) -> <> (state == OFF) 
-2.  []((x == DISABLE) -> <>(state == OFF)) 
-3.  [](count == 0) -> <>(state == OFF)
-4.  []( (state == HOLD) -> ((x != DISABLE) && (x != RESUME) )) -> <>(state == STANDBY) 
+1.  `(x == ENABLE) -> <> (state == OFF) `
+2.  `[]((x == DISABLE) -> <>(state == OFF)) `
+3.  `[](count == 0) -> <>(state == OFF)`
+4.  `[]( (state == HOLD) -> ((x != DISABLE) && (x != RESUME) )) -> <>(state == STANDBY) `
 
 To compile and verify the model you can use 'ispin' (SPIN graphical environment),
 or, using the command line, with:
 
-- spin -a cruise.pml
-- gcc -o pan pan.c
-- ./pan -N p1 (for property p1)
-- ./pan -N p2 (for property p2)
+- `spin -a cruise.pml`
+- `gcc -o pan pan.c`
+- `./pan -N p1 (for property p1)`
+- `./pan -N p2 (for property p2)`
