 ```
 
+This is how `genMockFromModule` will mock the following data types:
+
+#### `Function`
+
+Creates a new [mock function](https://jestjs.io/docs/en/mock-functions.html). The new function has no formal parameters and when called will return `undefined`. This functionality also applies to `async` functions.
+
+#### `Class`
+
+Creates new class. The interface of the original class is maintained, all of the class member functions and properties will be mocked.
+
+#### `Object`
+
+Creates a new deeply cloned object. The object keys are maintained and their values are mocked.
+
+#### `Array`
+
+Creates a new empty array, ignoring the original.
+
+#### `Primitives`
+
+Creates a new property with the same primitive value as the original property.
+
+Example:
+
+```
+// example.js
+module.exports = {
+  function: function square(a, b) {
+    return a * b;
+  },
+  asyncFunction: async function asyncSquare(a, b) {
+    const result = await a * b;
+    return result;
+  },
+  class: new class Bar {
+    constructor() {
+      this.array = [1, 2, 3];
+    }
+    foo() {}
+  },
+  object: {
+    baz: 'foo',

+      fiz: 1,
+      buzz: [1, 2, 3],

+  array: [1, 2, 3],
+  number: 123,
+  string: 'baz',
+  boolean: true,
+  symbol: Symbol.for('a.b.c'),
+};
+```
