README.md: use more standard conform syntax [minor]

 ### Dependencies
 You'll probably need a decent ncurses library to get this to work. I
 have provided a binary that depends on ncurses 4.2 & glibc6.
 
 ### Building and installing cmatrix
 To install cmatrix, in the cmatrix directory run:
-- `./configure`
-- `make`
-- `make install`
+```
+./configure
+make
+make install
+```
 
 ### Running cmatrix
 After you have installed cmatrix just run `cmatrix` to run cmatrix :)
