 How to write a Sink test
 ------------------------
 
-    test('should have foo', 1, function() {
-      $.ajax('/foo', function(resp) {
-        ok(resp.stat == '200');
-      });
-    });
+``` js
+test('should have foo', 1, function() {
+  $.ajax('/foo', function(resp) {
+    ok(resp.stat == '200');
+  });
+});
+```
 
 Loading a suite of tests
 ------------------------
 
 The above example illustrates the basic syntax of a single test, however loading your tests is done via the *sink* module which exports the test and ok methods. See the example below:
 
-    sink('my module', function(test, ok, before, after) {
-      before(function () {
-        // run this before every test
-      });
+``` js
+sink('my module', function(test, ok, before, after) {
+  before(function () {
+    // run this before every test
+  });
 
-      after(function () {
-        // run this after every test
-      });
+  after(function () {
+    // run this after every test
+  });
 
-      test('should have foo', 2, function() {
-        ok(true, 'this is basically true');
-        ok(1 == 1, 'also true for you math majors');
-      });
-    });
+  test('should have foo', 2, function () {
+    ok(true, 'this is basically true');
+    ok(1 == 1, 'also true for you math majors');
+  });
+});
 
-    sink('another module', function (t, o, b, a) {
-      test('a failure', 1, function () {
-        ok(1 == 2, 'should fail');
-      });
-    });
+sink('another module', function (t, o, b, a) {
+  test('a failure', 1, function () {
+    ok(1 == 2, 'should fail');
+  });
+});
 
-    start(); // start all test modules
+start(); // start all test modules
+```
 
 Browser support
 ---------------
 
 Any browser that supports JavaScript as well as Headless via command line with Node. (see below)
 
-    // tests.js
-    /** this snippet can be found in src/headless.js */
-    var sink = require('path/to/sink');
-    var start = sink.start;
-    sink = sink.sink;
+``` js
+// tests.js
+/** this snippet can be found in src/headless.js */
+var sink = require('path/to/sink');
+var start = sink.start;
+sink = sink.sink;
 
-    sink('some module', function (test, ok) {
-      // write tests
-    });
+sink('some module', function (test, ok) {
+  // write tests
+});
 
-    sink('another module', function (test, ok) {
-      // write tests
-    });
+sink('another module', function (test, ok) {
+  // write tests
+});
 
-    start();
+start();
+```
 
 in your terminal
 
-    % node path/to/my/tests.js
+    $ node path/to/my/tests.js
 
 Happy testing!
