+Validate Embedded
+=================
+
+This library provides the `Validate` constraint for the
+[Symfony Validator Component](https://github.com/symfony/validator).
+
+This constraint behaves similar to the built-in `Valid` constraint, but respects
+the `groups` option. Additionally, it adds an option to specify the validation
+groups to target on the embedded object(s).
+
+## Installation
+
+Open a command console, enter your project directory and execute the following
+command to download the latest stable version of this bundle:
+
+```bash
+$ composer require fluoresce/validate-embedded
+```
+
+This command requires you to have Composer installed globally, as explained in
+the [installation chapter](https://getcomposer.org/doc/00-intro.md) of the
+Composer documentation.
+
+## Documentation
+
+_The following examples assume you are using the full Symfony framework, though
+this package can be used in any project that has the Symfony Validator Component
+available_
+
+### Basic Usage
+
+This example shows an `Author` which has a collection of `Book`s. When
+validation is run for `group1` on `Author`, it will cascade to all embedded
+`Book` instances.
+
+The behaviour here is slightly different to the standard `Valid` constraint, as
+validation of the `Book` instances is run with the default group.
+
+```php
+<?php
+
+use Fluoresce\ValidateEmbedded\Constraints as Fluoresce;
+
+class Author
+{
+    /**
+     * @var Book[]
+     * @Fluoresce\Validate(groups={"group1"});
+     */
+    private $books;
+}
+```
+
+```php
+<?php
+
+use Symfony\Component\Validator\Constraints as Assert;
+
+class Book
+{
+    /**
+     * @var string
+     * @Assert\NotBlank()
+     */
+    private $title;
+}
+```
+
+### Specifying Embedded Validation Groups
+
+Imagine we want to specify different validation groups to be run on the `Book`
+instances. We can target these by specifying them in the `Validate` annotation.
+
+```php
+<?php
+
+use Fluoresce\ValidateEmbedded\Constraints as Fluoresce;
+
+class Author
+{
+    /**
+     * @var Book[]
+     * @Fluoresce\Validate(embeddedGroups={"bookgroup1"});
+     */
+    private $books;
+}
+```
+
+```php
+<?php
+
+use Symfony\Component\Validator\Constraints as Assert;
+
+class Book
+{
+    /**
+     * @var string
+     * @Assert\NotBlank(groups={"bookgroup1"})
+     */
+    private $title;
+}
+```
+
+Now whenever an `Author` instance is validated, the embedded `Book`s will be
+validated with validation group `bookgroup1`.
+
+### Combining All Options
+
+This example combines behaviour from the previous ones to show how it operates
+together.
+
+```php
+<?php
+
+use Fluoresce\ValidateEmbedded\Constraints as Fluoresce;
+
+class Author
+{
+    /**
+     * @var Book[]
+     * @Fluoresce\Validate(groups={"group1"}, embeddedGroups={"bookgroup1"});
+     */
+    private $books;
+}
+```
+
+```php
+<?php
+
+use Symfony\Component\Validator\Constraints as Assert;
+
+class Book
+{
+    /**
+     * @var string
+     * @Assert\NotBlank(groups={"bookgroup1"})
+     */
+    private $title;
+}
+```
