-[documentation]: #
+This package is the core of CASL. It includes logic responsible for [checking][check-abilities] and [defining][define-abilities] permissions.
+
+## Installation
+
+```sh
+npm install @casl/ability
+```
+
+## Getting Started
+
+CASL concentrates all attention at what a user can actually do and allows to create abilities in DSL style. Lets see how
+
+### 1. Defining Abilities
+
+`AbilityBuilder` allows to define abilities using DSL:
+
+```js
+import { AbilityBuidler } from '@casl/abiltiy'
+
+const ability = AbilityBuilder.define((can, cannot) => {
+  can('protect', 'Website')
+  cannot('delete', 'Website')
+})
+
+class Website {}
+
+console.log(ability.can('delete', new Website())) // false
+```
+
+If you would like to define abilities in own function, it'd better to use its `extract` method:
+
+```js
+import { AbilityBuidler, Ability } from '@casl/abiltiy'
+
+function defineAbilityFor(user) {
+  const { rules, can, cannot } = AbilityBuilder.extract()
+
+  if (user.isAdmin) {
+    can('manage', 'all')
+  } else {
+    can('read', 'all')
+    can('manage', 'Post', { author: 'me' })
+    cannot('delete', 'Post')
+  }
+
+  return new Ability(rules)
+}
+```
+
+Also you can combine similar rules together:
+
+```js
+const { can, rules } = AbilityBuilder.extract()
+
+can(['read', 'update'], 'User', { id: 'me' })
+can(['read', 'update'], ['Post', 'Comment'], { authorId: 'me' })
+
+console.log(rules)
+```
+
+See [Defining Abilities][define-abilities] for details.
+
+### 2. Checking rules
+
+Later on you can check abilities by using `can` and `cannot`.
+
+```js
+// true if user can read at least one Post
+ability.can('read', 'Post')
+
+// true if user cannot update a post
+const post = new Post({ title: 'What is CASL?', authorId: 'not_me' })
+ability.cannot('update', post)
+```
+
+See [Check Abilities][check-abilities] for details.
+
+### 3. Serializing rules
+
+As rules are plain objects, they can be easily serialized and cached in session or JWT token or even [saved to any database][store-rules] and added dynamically later in admin panel.
+
+```js
+const jwt = require('jsonwebtoken')
+const payload = {
+  rules: ability.rules
+}
+
+jwt.sign(payload, secret, (error, token) => {
+  if (error) {
+    return next(error)
+  }
+
+  // later you can send this token to client
+  // and restore Ability on the client using `jwt.verify`
+  console.log(token)
+})
+```
+
+See [Caching Abilities][cache-rules] for details.
+
+### 4. Extra
+
+This package also provides `@casl/ability/extra` submodule which contains helper functions that can construct a database query based on permissions or extract some information from them.
+
+```js
+import { rulesToQuery } from '@casl/ability/extra'
+
+function ruleToSequelizeQuery(rule) {
+  return rule.inverted ? { not: rule.conditions } : rule.conditions
+}
+
+function toSequelizeQuery(rules) {
+  return rulesToQuery(rules, ruleToSequelizeQuery)
+}
+
+// now you can construct sequelize query based on Ability
+const query = toSequelizeQuery(ability.rulesFor('read', 'Post'))
+```
+
+[@casl/mongoose](/packages/casl-mongoose) uses `rulesToQuery` function to construct queries to MongoDB database.
+
+See [Storing Abilities][storing-abilities] for details.
