-Compiling and Running
----------------------
+### Compiling and Running
 
 This program usually compiles under both GCC and clang. Build with:
 
-    $(CC) -std=c99 -o tbfs prog.c
+```sh
+$(CC) -std=c99 -o tbfs prog.c
+```
 
 where $(CC) is cc, gcc, clang, or somet other c compiler.
 
 You can then run it with:
-    cat <input file> | ./tbfs
+
+```sh
+cat <input file> | ./tbfs
+```
 
 Examples:
-    ./tbfs < maze 
-    ./tbfs < prog.c
 
-Issues
------------
+```sh
+./tbfs < maze 
+./tbfs < prog.c

 moving the cursor and changing colors.
