+# Usage Examples
+
+```js
+copy: {
+  main: {
+    files: [
+      {src: ['path/*'], dest: 'dest/', filter: 'isFile'}, // includes files in path
+      {src: ['path/**'], dest: 'dest/'}, // includes files in path and its subdirs
+      {expand: true, cwd: 'path/', src: ['**'], dest: 'dest/'}, // makes all src relative to cwd
+      {expand: true, flatten: true, src: ['path/**'], dest: 'dest/', filter: 'isFile'} // flattens results to a single level
+    ]
+  }
+}
