+==================
 
 Introduction
 ------------
@@ -7,51 +14,61 @@ Introduction
 The ReflectionDocBlock component of phpDocumentor provides a DocBlock parser
 that is 100% compatible with the [PHPDoc standard](http://phpdoc.org/docs/latest).
 
-With this component can a library provide support for annotations via DocBlocks
+With this component, a library can provide support for annotations via DocBlocks
 or otherwise retrieve information that is embedded in a DocBlock.
 
-> **Note**: *this is a core component of phpDocumentor and is constantly being
-> optimized for performance.*
-
 Installation
 ------------
 
-You can install the component in the following ways:
-
-* Use the official Github repository (https://github.com/phpDocumentor/ReflectionDocBlock)
-* Via composer (add the Github Repository as VCS repository in your composer.yml)
+```bash
+composer require phpdocumentor/reflection-docblock
+```
 
 Usage
 -----
 
-The ReflectionDocBlock component is designed to work in an identical fashion to
-PHP's own Reflection extension (http://php.net/manual/en/book.reflection.php).
+In order to parse the DocBlock one needs a DocBlockFactory that can be
+instantiated using its `createInstance` factory method like this:
 
-Parsing can be initiated by instantiating the
-`\phpDocumentor\Reflection\DocBlock()` class and passing it a string containing
-a DocBlock (including asterisks) or by passing an object supporting the
-`getDocComment()` method.
+```php
+$factory  = \phpDocumentor\Reflection\DocBlockFactory::createInstance();
+```
 
-> *Examples of objects having the `getDocComment()` method are the
-> `ReflectionClass` and the `ReflectionMethod` classes of the PHP
-> Reflection extension*
+Then we can use the `create` method of the factory to interpret the DocBlock.
+Please note that it is also possible to provide a class that has the
+`getDocComment()` method, such as an object of type `ReflectionClass`, the
+create method will read that if it exists.
 
-Example:
+```php
+$docComment = <<<DOCCOMMENT
+/**
+ * This is an example of a summary.
+ *
+ * This is a Description. A Summary and Description are separated by either
+ * two subsequent newlines (thus a whiteline in between as can be seen in this
+ * example), or when the Summary ends with a dot (`.`) and some form of
+ * whitespace.
+ */
+DOCCOMMENT;
 
-    $class = new ReflectionClass('MyClass');
-    $phpdoc = new \phpDocumentor\Reflection\DocBlock($class);
+$docblock = $factory->create($docComment);
+```
 
-or
+The `create` method will yield an object of type `\phpDocumentor\Reflection\DocBlock`
+whose methods can be queried:
 
-    $docblock = <<<DOCBLOCK
-    /**
-     * This is a short description.
-     *
-     * This is a *long* description.
-     *
-     * @return void
-     */
-    DOCBLOCK;
+```php
+// Contains the summary for this DocBlock
+$summary = $docblock->getSummary();
 
-    $phpdoc = new \phpDocumentor\Reflection\DocBlock($docblock);
+// Contains \phpDocumentor\Reflection\DocBlock\Description object
+$description = $docblock->getDescription();
 
+// You can either cast it to string
+$description = (string) $docblock->getDescription();
+
+// Or use the render method to get a string representation of the Description.
+$description = $docblock->getDescription()->render();
+```
+
+> For more examples it would be best to review the scripts in the [`/examples` folder](/examples).

+Reconstituting a DocBlock
+=========================
+
+ReflectionDocBlock not only allows you to read and parse DocBlocks, but also to reconstruct them. This is useful if you need to add, remove, or modify tags in your codebase programmatically. For example, you might want to update type information, add custom tags, or strip deprecated tags as part of a refactoring or code generation process.
+
+Below is a practical example of how to reconstitute a DocBlock using this library:

+ReflectionDocBlock Documentation
+===========================================
+
+ReflectionDocBlock is a PHP library that provides a DocBlock parser fully compatible with the PHPDoc standard. It allows you to parse, interpret, and extract information from DocBlocks in your PHP code, enabling support for annotations and metadata extraction.
+
+Key Features and Use Cases
+--------------------------
+- **Documentation Generation**: Used as a core component in tools like phpDocumentor to generate API documentation from your code's DocBlocks.
+- **Type and Metadata Extraction**: Integrations and tools use this library to gather type information and other metadata, enabling advanced features such as static analysis, code introspection, and automated serialization.
+- **Serializer Support**: Helps serializers and similar tools to interpret type information in array and object structures, making it easier to transform nested objects correctly.
+- **DocBlock Reconstitution**: Not only can you read DocBlocks, but you can also reconstruct them. This is useful for adding, removing, or modifying tags in your codebase programmatically.
+- **Standalone or Integrated**: Designed for standalone use, but also serves as a key component of the phpDocumentor suite.
+
+Unique Advantages
+-----------------
+- **Simple, Intuitive API**: Focus on ease of use, so you can work with DocBlocks without needing to understand the complexities of parsing.
+- **Widely Adopted**: Used by over 1000 packages on Packagist, making it a proven and reliable choice for PHP developers.
+- **Actively Maintained**: Supports PHP 7.4 and 8+, and is maintained by the phpDocumentor team and contributors.
+
+Quick Start Example
+-------------------
+Here's a minimal example of how to use ReflectionDocBlock in your project:
+
+.. literalinclude:: examples/01-interpreting-a-simple-docblock.php
+   :language: php
+   :caption: examples/01-interpreting-a-simple-docblock.php

+Upgrade Guide to v6
+===================
+
+This guide helps you upgrade your project to ReflectionDocBlock v6. It covers breaking changes, removals, new features, and migration tips to ensure a smooth transition.
+
+Supported PHP Versions
+----------------------
+- v6 requires PHP 7.4 or higher (PHP 8+ recommended).
+
+Breaking Changes & Removals
+---------------------------
+- **Removal of `::create` static method for type-based tags**
+    - The `create` static method has been removed from tag classes that represent type definitions, such as `@param` and `@return` tags. Most users will not be affected, as these methods are rarely used directly. The deprecation notice for these methods was present throughout v5.
+    - **Migration:**
+        - If you are instantiating these tag objects directly, use the tag factory or the recommended construction pattern instead.
+        - Before:
+            .. code-block:: php
+
+               $tag = Param::create($body);
+        - After:
+            .. code-block:: php
+
+               $factory = \phpDocumentor\Reflection\DocBlock\Tags\Factory\StandardTagFactory::createInstance();
+               $tag = $factory->create('@param int $foo');
+
+- **StandardTagFactory instantiation**
+    - `StandardTagFactory` must now be created via `createInstance()`.
+    - **Migration:**
+        - Before:
+            .. code-block:: php
+
+               $factory = new StandardTagFactory();
+        - After:
+            .. code-block:: php
+
+               $factory = StandardTagFactory::createInstance();
+
+- **Removed methods**
+    - `Method::getArguments` has been removed.
+    - `Method::create` has been removed.
+    - **Migration:**
+        - Refactor code to use the new API for method arguments and creation.
+
+TypeResolver Upgrade
+-------------------
+- **Generics Support**: The TypeResolver component now supports generics,
+    which replaces the previous `Collection` type handling. This allows
+    for more accurate and expressive type definitions, such as `MyClass<int, MyClass>` or `Collection<MyClass>`,
+    and improves compatibility with modern PHPDoc standards.
+
+- For more details and advanced migration scenarios, consult the `TypeResolver upgrade guide <https://docs.phpdoc.org/components/type-resolver/guides/upgrade-v1-to-v2.html#upgrade-to-version-2>`_

+ * If you do not want to use the DescriptionFactory you can pass a body template and tag listing like this:
