+
+# Introduction
+
+Imagine you run facebook and you want visitors to sign up on the website with real names and not something like `l337_p@nda` in the first name field. How would you define the limitations of what can be inputted and validate it against the set rules?
+
+This is joi, joi allows you to create *blueprints* or *schemas* for JavaScript objects (an object that stores information) to ensure *validation* of key information.
+
+# API
+See the detailed [API Reference](https://github.com/hapijs/joi/blob/v11.4.0/API.md).
+
+# Example
+
+```javascript
+const Joi = require('joi');
+
+const schema = Joi.object().keys({
+    username: Joi.string().alphanum().min(3).max(30).required(),
+    password: Joi.string().regex(/^[a-zA-Z0-9]{3,30}$/),
+    access_token: [Joi.string(), Joi.number()],
+    birthyear: Joi.number().integer().min(1900).max(2013),
+    email: Joi.string().email()
+}).with('username', 'birthyear').without('password', 'access_token');
+
+// Return result.
+const result = Joi.validate({ username: 'abc', birthyear: 1994 }, schema);
+// result.error === null -> valid
+
+// You can also pass a callback which will be called synchronously with the validation result.
+Joi.validate({ username: 'abc', birthyear: 1994 }, schema, function (err, value) { });  // err === null -> valid
+
+```
+
+The above schema defines the following constraints:
+* `username`
+    * a required string
+    * must contain only alphanumeric characters
+    * at least 3 characters long but no more than 30
+    * must be accompanied by `birthyear`
+* `password`
+    * an optional string
+    * must satisfy the custom regex
+    * cannot appear together with `access_token`
+* `access_token`
+    * an optional, unconstrained string or number
+* `birthyear`
+    * an integer between 1900 and 2013
+* `email`
+    * a valid email address string
+
+# Usage
+
+Usage is a two steps process. First, a schema is constructed using the provided types and constraints:
+
+```javascript
+const schema = {
+    a: Joi.string()
+};
+```
+
+Note that **joi** schema objects are immutable which means every additional rule added (e.g. `.min(5)`) will return a
+new schema object.
+
+Then the value is validated against the schema:
+
+```javascript
+const {error, value} = Joi.validate({ a: 'a string' }, schema);
+
+// or
+
+Joi.validate({ a: 'a string' }, schema, function (err, value) { });
+```
+
+If the input is valid, then the error will be `null`, otherwise it will be an Error object.
+
+The schema can be a plain JavaScript object where every key is assigned a **joi** type, or it can be a **joi** type directly:
+
+```javascript
+const schema = Joi.string().min(10);
+```
+
+If the schema is a **joi** type, the `schema.validate(value, callback)` can be called directly on the type. When passing a non-type schema object,
+the module converts it internally to an object() type equivalent to:
+
+```javascript
+const schema = Joi.object().keys({
+    a: Joi.string()
+});
+```
+
+When validating a schema:
+
+* Values (or keys in case of objects) are optional by default.
+
+    ```javascript
+    Joi.validate(undefined, Joi.string()); // validates fine
+    ```
+
+    To disallow this behavior, you can either set the schema as `required()`, or set `presence` to `"required"` when passing `options`:
+
+    ```javascript
+    Joi.validate(undefined, Joi.string().required());
+    // or
+    Joi.validate(undefined, Joi.string(), /* options */ { presence: "required" });
+    ```
+
+* Strings are utf-8 encoded by default.
+* Rules are defined in an additive fashion and evaluated in order after whitelist and blacklist checks.
+
+# Browsers
+
+Joi doesn't directly support browsers, but you could use [joi-browser](https://github.com/jeffbski/joi-browser) for an ES5 build of Joi that works in browsers, or as a source of inspiration for your own builds.
