 ## TypeScript
 
-This library contains type definitions for TypeScript. When you use TypeScript we highly recommend using the `Hook.Singular` constructor for your hooks as this allows you to pass along type information for the options object. For example:
+This library contains type definitions for TypeScript.
+
+### Type support for `Singular`:
 
 ```ts
+import { Hook } from 'before-after-hook';
 
-import {Hook} from 'before-after-hook'
+type O = { foo: string }; // type for options
+type R = { bar: number }; // type for result
+type E = Error; // type for error
 
-interface Foo {
-  bar: string
-  num: number;
-}
+const hook = new Hook.Singular<O, R, E>();
 
-const hook = new Hook.Singular<Foo>();
+hook.before((options) => {
+  // `options.foo` has `string` type
 
-hook.before(function (foo) {
+  // not allowed
+  options.foo = 42;
 
-  // typescript will complain about the following mutation attempts
-  foo.hello = 'world'
-  foo.bar = 123
+  // allowed
+  options.foo = 'Forty-Two';
+});
 
-  // yet this is valid
-  foo.bar = 'other-string'
-  foo.num = 123
-})
+const hookedMethod = hook(
+  (options) => {
+    // `options.foo` has `string` type
 
-const foo = hook(function(foo) {
-  // handle `foo`
-  foo.bar = 'another-string'
-}, {bar: 'random-string'})
+    // not allowed, because it does not satisfy the `R` type
+    return { foo: 42 };
 
-// foo outputs
-{
-  bar: 'another-string',
-  num: 123
-}
+    // allowed
+    return { bar: 42 };
+  },
+  { foo: 'Forty-Two' }
+);
+```
+
+You can choose not to pass the types for options, result or error. So, these are completely valid:
+
+```ts
+const hook = new Hook.Singular<O, R>();
+const hook = new Hook.Singular<O>();
+const hook = new Hook.Singular();
+```
+
+In these cases, the omitted types will implicitly be `any`.
+
+### Type support for `Collection`:
+
+`Collection` also has strict type support. You can use it like this:
+
+```ts
+import { Hook } from 'before-after-hook';
+
+type HooksType = {
+  add: { O: { type: string }; R: { id: number }; E: Error };
+  save: { O: { type: string }; R: { id: number } };
+  read: { O: { id: number; foo: number } };
+  destroy: { O: { id: number; foo: string } };
+};
+
+const hooks = Hook.Collection<HooksType>();
+
+hooks.before('destroy', (options) => {
+  // `options.id` has `number` type
+});
+
+hooks.error('add', (err, options) => {
+  // `options.type` has `string` type
+  // `err` is `instanceof Error`
+});
+
+hooks.error('save', (err, options) => {
+  // `options.type` has `string` type
+  // `err` has type `any`
+});
+
+hooks.after('save', (result, options) => {
+  // `options.type` has `string` type
+  // `result.id` has `number` type
+});
+
+hooks.before(['add', 'save'], (options) => {
+  // `options.type` has `string` type
+});
+
+hooks.error(['add', 'save'], (err, options) => {
+  // `options.type` has `string` type
+  // `err` has `any` type, because `E` was not defined for `save`
+});
+
+hooks.before(['read', 'destroy'], (options) => {
+  // `options.id` has `number` type
+  // `options.foo` has `number | string` type
+});
+```
+
+You can choose not to pass the types altogether. In that case, everything will implicitly be `any`:
+
+```ts
+const hook = new Hook.Collection();
 ```
 
-An alternative import:
+Alternative imports:
