+# Exceptions
+
+### Create instance of exception
+
+This package contains a lot of exceptions. Each of them contains static method `create()` with proper arguments that is used to create instance of the exception. Example:
+
+```php
+use Meritoo\Common\Exception\Bundle\IncorrectBundleNameException;
+throw IncorrectBundleNameException::create('RisusIpsum');
+```
+
+### Base exception for unknown type of something
+
+##### Short description
+
+It's a `Meritoo\Common\Exception\Base\UnknownTypeException` class. Related to `Meritoo\Common\Type\Base\BaseType` class that represents type of something, e.g. type of button, order.
+
+##### Usage
+
+You can extend `Meritoo\Common\Exception\Base\UnknownTypeException` class and create your own static method, e.g. `createException()`, which will be used create instance of the exception. Inside the `createException()` method you can call `parent::create()` method.
+
+##### Example
+
+```php
+<?php
+
+namespace Your\Package\Exception\Type;
+
+use Meritoo\Common\Exception\Base\UnknownTypeException;
+use Your\Package\Type\SimpleType;
+
+class UnknownSimpleTypeException extends UnknownTypeException
+{
+    /**
+     * Creates exception
+     *
+     * @param string $unknownType Unknown and simple type
+     * @return UnknownSimpleTypeException
+     */
+    public static function createException($unknownType)
+    {
+        /* @var UnknownSimpleTypeException $exception */
+        $exception = parent::create($unknownType, new SimpleType(), 'my simple type of something');
+
+        return $exception;
+    }
+}
+```
