+### Dynamic keys
+
+```js
+type Items = {
+  [key: string]: Item
+}
+```
+
+See: [Dynamic object keys](https://flow.org/docs/objects.html#objects-as-maps)
+
+### Enums
+
+```js
+type Suit = "Diamonds" | "Clubs" | "Hearts" | "Spades"
+
+const countries = {
+  US: "United States",
+  IT: "Italy",
+  FR: "France"
+}
+
+type Country = $Keys<typeof countries>
+```
+
+See: [Enums](https://flow.org/docs/utility-types.html#keyst)
+
+### Type aliases
+
+```js
+type Tree = {
+  foo: string,
+  bar: number,
+  qux: (foo: string, bar: number) => boolean
+}
+
+type Generic<T> = {
+  foo: T
+}
+```
+
+See: [Type aliases](https://flow.org/docs/quick-reference.html#type-aliases)
+
+### Generic classes
+
+```js
+class GenericClass<T> {
+  x: T
+  constructor (x: T) { ... }
+}
+
+var n: GenericClass<number> = new GenericClass(0)
+```
+
+See: [Generic classes](https://flow.org/docs/quick-reference.html#generics)
+
+### Interfaces
+
+```js
+interface Jsonable {
+  toJSON(): string
+}
+
+class Foo {
+  toJSON() { return '{}' }
+}
+
+(new Foo: Jsonable)
+```
+
+See: [Interfaces](https://flow.org/docs/quick-reference.html#interfaces)
+
+### Functions
+
+```js
+const callback: () => void = function () {}
+```
+
+```js
+function filter<T> (
+  list: Array<T>,
+  callback: (item: T) => boolean
+): Array<T> {
+  ···
+}
+```
+
+See: [Functions](https://flow.org/docs/functions.html)
+
+### Imports
+
+```js
+import type { Person } from '../person'
+import typeof Config from '../config'
+```
+
+```js
+export type Person = { id: string }
+```
+
+### Comment syntax
+
+```js
+/*::
+  export type Foo = { ... }
+*/
+
+function add(n /*: number */) { ... }
+```
+
+### React
+
+```js
+React$Element<any>
+```
+
+```js
+class Foo extends React.Component {
+  /*:: state: { open: boolean } */
+  /*:: props: { open: boolean } */
+}
+```
+## Examples
+
+### Examples
+
+```js
+var myNumbers: Array<number> = [42]
+function foo(): any { return 42 }
+var b: boolean = false
+var b: ?boolean = false  /* maybe */
+var b: string | boolean = false
+
+var a: Class<MyClass> = MyClass
+var b: MyClass = new a()
+```
+
+### Function signature
+
+```js
+var add: ((num1: number, num2: number) => number) = function (num1, num2) {
+  return num1 + num2
+}
+```
+
+You don't need to do this! It's inferred. This is better:
+
+```js
+var add = function (num1: number, num2: number) {
+  return num1 + num2
+}
+```
