-# Concrete API
-
-There are many micro-frameworks that rely on magic methods. We don't. In this
-document we're going to explore the Respect\Validation API without fluent interfaces
-or magic methods. We'll use a traditional dependency injection approach.
-
-```php
-use Respect\Validation\ValidatorBuilder as v;
-
-$usernameValidator = v::alnum()->notSpaced()->length(1, 15);
-$usernameValidator->isValid('alganet'); // true
-```
-
-If you `var_dump($usernameValidator)`, you'll see a composite of objects with
-`Respect\Validation\Validators\Alnum`, `Respect\Validation\Validators\Spaced` wrapped in `Respect\Validation\Validators\Not` and
-`Respect\Validation\Validators\Length`. There is a specific object for each validator, and
-the chain only builds the structure. You can build it by yourself:
-
-```php
-use Respect\Validation\Validators;
-use Respect\Validation\ValidatorBuilder;
-
-$usernameValidator = ValidatorBuilder::init(
-    new Validators\Alnum(),
-    new Validators\Not(
-        new Validators\Spaced(),
-    ),
-    new Validators\Length(1, 15),
-);
-$usernameValidator->isValid('alganet'); // true
-```
-
-This is still a very lean API. You can use it in any dependency injection
-container or test it in the way you want. Nesting is still possible:
-
-```php
-use Respect\Validation\Validators;
-
-$usernameValidator = ValidatorBuilder::init(
-    new Validators\Key(
-        'name',
-        new Validators\AllOf(
-            new Validators\Alnum(),
-            new Validators\Not(
-                new Validators\Spaced(),
-            ),
-            new Validators\Length(1, 15),
-        )
-    )
-);
-$userValidator->isValid(['name' => 'alganet']); // true
-```
-
-## How It Works?
-
-The Respect\Validation chain is an
-[internal DSL](http://martinfowler.com/bliki/InternalDslStyle.html).
-It acts in the creational realm of objects (where Abstract Factories and Builders
-live), and it's only job is to make validator construction terse and fluent.
-
-## FAQ
-
-> Is `v` in `v::something` a class name?
-
-No! The class is `Respect\Validation\ValidatorBuilder`, we suggest `v` as a very short alias.
-
-> Is `v::something()` a static call?
-
-Yes. Just like the default `DateTime::createFromFormat()` or
-`Doctrine\ORM\Tools\Setup::createAnnotationMetadataConfiguration()`. It builds
-something complex and returns for you.
-
-> I really don't like static calls, can I avoid it?
-
-Yes. Just use `$validator = ValidatorBuilder::create();` each time you want a new validator,
-and continue from there.
-
-> Do you have a static method for each validator?
-
-No. We use `__callStatic()`.
-
-> Magic methods are slow! Why do you use them?
-
-They're optional. If you use the `new` interface, they won't be called.
-
-(still, do some benchmarks, you'd be surprised with our implementation).
