 Once Go is installed, you should set up a GOPATH to avoid clobbering your Go environment's root directory with third party packages.
 
 Set up a GOPATH. On Unix, do something like this
-
-    $ export GOPATH=$HOME/gocode
-    $ mkdir -p $GOPATH
+```shell script
+$ export GOPATH=$HOME/gocode
+$ mkdir -p $GOPATH
+```
 
 and on Windows, do something like this (for cmd.exe):
-
-    c:\> set GOPATH=%USERPROFILE%\gocode
-    c:\> mkdir %GOPATH%
+```shell script
+c:\> set GOPATH=%USERPROFILE%\gocode
+c:\> mkdir %GOPATH%
+```
 
 Then, it's time to install Grumble. The following line should do the trick:
-
-    $ go get mumble.info/grumble/cmd/grumble
+```shell script
+$ go get mumble.info/grumble/cmd/grumble
+```
 
 And that should be it. Grumble has been built, and is available in $GOPATH/bin as 'grumble'.
