 ## Usage
 
 For the impatient, here\'s how to compile a hello world for armv7:
 
-    cd ~/src/dockcross
-    docker run --rm dockcross/linux-armv7 > ./dockcross-linux-armv7
-    chmod +x ./dockcross-linux-armv7
-    ./dockcross-linux-armv7 bash -c '$CC test/C/hello.c -o hello_arm'
+```bash
+cd ~/src/dockcross
+docker run --rm dockcross/linux-armv7 > ./dockcross-linux-armv7
+chmod +x ./dockcross-linux-armv7
+./dockcross-linux-armv7 bash -c '$CC test/C/hello.c -o hello_arm'
+```
 
 Note how invoking any toolchain command (make, gcc, etc.) is just a matter of prepending the **dockcross** script on the commandline:
 
-    ./dockcross-linux-armv7 [command] [args...]
+```bash
+./dockcross-linux-armv7 [command] [args...]
+```
 
 The dockcross script will execute the given command-line inside the container, along with all arguments passed after the command. Commands that evaluate environmental variables in the image, like **$CC** or **$CXX** above, should be executed in [bash -c]. The present working directory is mounted within the image, which can be used to make source code available in the Docker container.
