 `rustc -O interval.rs` to produce the `interval` binary executable.
 
 ###How to Use
-`interval` can be run at the command line with the following syntax:
-`./interval [input file] [output file]`.
+`interval` can be run at the command line with the following syntax:  
+`./interval [input file] [output file]`  
 This will attempt to read Interval code from the input file, generate audio based on it, and emit the resulting data,
 prefixed with a suitable RIFF header, into the output file (which will be in `.wav` format). The audio stream is signed
 16-bit little endian samples, at a sample rate defined by a static variable in the source code (48 kHz by default).
 
 ###Example Usage
-Under Linux with ALSA, you can compile and play a .ITV source file with a command like this:
-`./interval test.itv`
+Under Linux with ALSA, you can compile and play a .ITV source file with a command like this:  
+`./interval test.itv`  
 This will write WAV data into `test.wav`, creating it if it does not exist and overwriting it if it does.
