+Introduction
+============
+
+The Doctrine Inflector has methods for inflecting text. The features include pluralization,
+singularization, converting between camelCase and under_score and capitalizing
+words.
+
+Installation
+============
+
+You can install the Inflector with composer:
+
+.. code-block:: console
+
+    $ composer require doctrine/inflector
+
+Usage
+=====
+
+Using the inflector is easy, you can create a new ``Doctrine\Inflector\Inflector`` instance by using
+the ``Doctrine\Inflector\InflectorFactory`` class:
+
+.. code-block:: php
+
+    use Doctrine\Inflector\InflectorFactory;
+
+    $inflector = InflectorFactory::create()->build();
+
+By default it will create an English inflector. If you want to use another language, just pass the language
+you want to create an inflector for to the ``createForLanguage()`` method:
+
+.. code-block:: php
+
+    use Doctrine\Inflector\InflectorFactory;
+    use Doctrine\Inflector\Language;
+
+    $inflector = InflectorFactory::createForLanguage(Language::SPANISH)->build();
+
+The supported languages are as follows:
+
+- ``Language::ENGLISH``
+- ``Language::ESPERANTO``
+- ``Language::FRENCH``
+- ``Language::NORWEGIAN_BOKMAL``
+- ``Language::PORTUGUESE``
+- ``Language::SPANISH``
+- ``Language::TURKISH``
+
+If you want to manually construct the inflector instead of using a factory, you can do so like this:
+
+.. code-block:: php
+
+    use Doctrine\Inflector\CachedWordInflector;
+    use Doctrine\Inflector\RulesetInflector;
+    use Doctrine\Inflector\Rules\English;
+
+    $inflector = new Inflector(
+        new CachedWordInflector(new RulesetInflector(
+            English\Rules::getSingularRuleset()
+        )),
+        new CachedWordInflector(new RulesetInflector(
+            English\Rules::getPluralRuleset()
+        ))
+    );
+
+Adding Languages
+----------------
+
+If you are interested in adding support for your language, take a look at the other languages defined in the
+``Doctrine\Inflector\Rules`` namespace and the tests located in ``Doctrine\Tests\Inflector\Rules``. You can copy
+one of the languages and update the rules for your language.
+
+Once you have done this, send a pull request to the ``doctrine/inflector`` repository with the additions.
+
+Custom Setup
+============
+
+If you want to setup custom singular and plural rules, you can configure these in the factory:
+
+.. code-block:: php
+
+    use Doctrine\Inflector\InflectorFactory;
+    use Doctrine\Inflector\Rules\Pattern;
+    use Doctrine\Inflector\Rules\Patterns;
+    use Doctrine\Inflector\Rules\Ruleset;
+    use Doctrine\Inflector\Rules\Substitution;
+    use Doctrine\Inflector\Rules\Substitutions;
+    use Doctrine\Inflector\Rules\Transformation;
+    use Doctrine\Inflector\Rules\Transformations;
+    use Doctrine\Inflector\Rules\Word;
+
+    $inflector = InflectorFactory::create()
+        ->withSingularRules(
+            new Ruleset(
+                new Transformations(
+                    new Transformation(new Pattern('/^(bil)er$/i'), '\1'),
+                    new Transformation(new Pattern('/^(inflec|contribu)tors$/i'), '\1ta')
+                ),
+                new Patterns(new Pattern('singulars')),
+                new Substitutions(new Substitution(new Word('spins'), new Word('spinor')))
+            )
+        )
+        ->withPluralRules(
+            new Ruleset(
+                new Transformations(
+                    new Transformation(new Pattern('^(bil)er$'), '\1'),
+                    new Transformation(new Pattern('^(inflec|contribu)tors$'), '\1ta')
+                ),
+                new Patterns(new Pattern('noflect'), new Pattern('abtuse')),
+                new Substitutions(
+                    new Substitution(new Word('amaze'), new Word('amazable')),
+                    new Substitution(new Word('phone'), new Word('phonezes'))
+                )
+            )
+        )
+        ->build();
+
+No operation inflector
+----------------------
+
+The ``Doctrine\Inflector\NoopWordInflector`` may be used to configure an inflector that doesn't perform any operation for
+pluralization and/or singularization. If will simply return the input as output.
+
+This is an implementation of the `Null Object design pattern <https://sourcemaking.com/design_patterns/null_object>`_.
+
+.. code-block:: php
+
+    use Doctrine\Inflector\Inflector;
+    use Doctrine\Inflector\NoopWordInflector;
+
+    $inflector = new Inflector(new NoopWordInflector(), new NoopWordInflector());
+
+Tableize
+========
+
+Converts ``ModelName`` to ``model_name``:
+
+.. code-block:: php
+
+    echo $inflector->tableize('ModelName'); // model_name
+
+Classify
+========
+
+Converts ``model_name`` to ``ModelName``:
+
+.. code-block:: php
+
+    echo $inflector->classify('model_name'); // ModelName
+
+Camelize
+========
+
+This method uses `Classify`_ and then converts the first character to lowercase:
+
+.. code-block:: php
+
+    echo $inflector->camelize('model_name'); // modelName
+
+Capitalize
+==========
+
+Takes a string and capitalizes all of the words, like PHP's built-in
+``ucwords`` function. This extends that behavior, however, by allowing the
+word delimiters to be configured, rather than only separating on
+whitespace.
+
+Here is an example:
+
+.. code-block:: php
+
+    $string = 'top-o-the-morning to all_of_you!';
+
+    echo $inflector->capitalize($string); // Top-O-The-Morning To All_of_you!
+
+    echo $inflector->capitalize($string, '-_ '); // Top-O-The-Morning To All_Of_You!
+
+Pluralize
+=========
+
+Returns a word in plural form.
+
+.. code-block:: php
+
+    echo $inflector->pluralize('browser'); // browsers
+
+Singularize
+===========
+
+Returns a word in singular form.
+
+.. code-block:: php
+
+    echo $inflector->singularize('browsers'); // browser
+
+Urlize
+======
+
+Generate a URL friendly string from a string of text:
+
+.. code-block:: php
+
+    echo $inflector->urlize('My first blog post'); // my-first-blog-post
+
+Unaccent
+========
+
+You can unaccent a string of text using the ``unaccent()`` method:
+
+.. code-block:: php
+
+    echo $inflector->unaccent('año'); // ano
+
+Legacy API
+==========
+
+The API present in Inflector 1.x is still available, but will be deprecated in a future release and dropped for 3.0.
+Support for languages other than English is available in the 2.0 API only.

+[![Code Coverage](https://scrutinizer-ci.com/g/Masterminds/html5-php/badges/coverage.png?b=master)](https://scrutinizer-ci.com/g/Masterminds/html5-php/?branch=master)
+[![Scrutinizer Code Quality](https://scrutinizer-ci.com/g/Masterminds/html5-php/badges/quality-score.png?b=master)](https://scrutinizer-ci.com/g/Masterminds/html5-php/?branch=master)
+[![Stability: Sustained](https://masterminds.github.io/stability/sustained.svg)](https://masterminds.github.io/stability/sustained.html)
+
+## Installation
+
+Install HTML5-PHP using [composer](http://getcomposer.org/).
+
+By adding the `masterminds/html5` dependency to your `composer.json` file:
+
+```json
+{
+  "require" : {
+    "masterminds/html5": "^2.0"
+  },
+}
+```
+
+By invoking require command via composer executable:
+
+```bash
+composer require masterminds/html5
+```
+
+## Basic Usage
+
+HTML5-PHP has a high-level API and a low-level API.
+
+Here is how you use the high-level `HTML5` library API:
+
+```php
+<?php
+// Assuming you installed from Composer:
+require "vendor/autoload.php";
+
+use Masterminds\HTML5;
+
+// An example HTML document:
+$html = <<< 'HERE'
+  <html>
+  <head>
+    <title>TEST</title>
+  </head>
+  <body id='foo'>
+    <h1>Hello World</h1>
+    <p>This is a test of the HTML5 parser.</p>
+  </body>
+  </html>
+HERE;
+
+// Parse the document. $dom is a DOMDocument.
+$html5 = new HTML5();
+$dom = $html5->loadHTML($html);
+
+// Render it as HTML5:
+print $html5->saveHTML($dom);
+
+// Or save it to a file:
+$html5->save($dom, 'out.html');
+```
+
+The `$dom` created by the parser is a full `DOMDocument` object. And the
+`save()` and `saveHTML()` methods will take any DOMDocument.
+
+### Options
+
+It is possible to pass in an array of configuration options when loading
+an HTML5 document.
+
+```php
+// An associative array of options
+$options = array(
+  'option_name' => 'option_value',
+);
+
+// Provide the options to the constructor
+$html5 = new HTML5($options);
+
+$dom = $html5->loadHTML($html);
+```
+
+The following options are supported:
+
+* `encode_entities` (boolean): Indicates that the serializer should aggressively
+  encode characters as entities. Without this, it only encodes the bare
+  minimum.
+* `disable_html_ns` (boolean): Prevents the parser from automatically
+  assigning the HTML5 namespace to the DOM document. This is for
+  non-namespace aware DOM tools.
+* `target_document` (\DOMDocument): A DOM document that will be used as the
+  destination for the parsed nodes.
+* `implicit_namespaces` (array): An assoc array of namespaces that should be
+  used by the parser. Name is tag prefix, value is NS URI.
+
+## The Low-Level API
+
+This library provides the following low-level APIs that you can use to
+create more customized HTML5 tools:
+
+- A SAX-like event-based parser that you can hook into for special kinds
+of parsing.
+- A flexible error-reporting mechanism that can be tuned to document
+syntax checking.
+- A DOM implementation that uses PHP's built-in DOM library.
+
+The unit tests exercise each piece of the API, and every public function
+is well-documented.
+
+### Parser Design
+
+The parser is designed as follows:
+
+- The `Scanner` handles scanning on behalf of the parser.
+- The `Tokenizer` requests data off of the scanner, parses it, clasifies
+it, and sends it to an `EventHandler`. It is a *recursive descent parser.*
+- The `EventHandler` receives notifications and data for each specific
+semantic event that occurs during tokenization.
+- The `DOMBuilder` is an `EventHandler` that listens for tokenizing
+events and builds a document tree (`DOMDocument`) based on the events.
+
+### Serializer Design
+
+The serializer takes a data structure (the `DOMDocument`) and transforms
+it into a character representation -- an HTML5 document.
+
+The serializer is broken into three parts:
+
+- The `OutputRules` contain the rules to turn DOM elements into strings. The
+rules are an implementation of the interface `RulesInterface` allowing for
+different rule sets to be used.
+- The `Traverser`, which is a special-purpose tree walker. It visits
+each node node in the tree and uses the `OutputRules` to transform the node
+into a string.
+- `HTML5` manages the `Traverser` and stores the resultant data
+in the correct place.
+
+The serializer (`save()`, `saveHTML()`) follows the
+[section 8.9 of the HTML 5.0 spec](http://www.w3.org/TR/2012/CR-html5-20121217/syntax.html#serializing-html-fragments).
+So tags are serialized according to these rules:
+
+- A tag with children: &lt;foo&gt;CHILDREN&lt;/foo&gt;
+- A tag that cannot have content: &lt;foo&gt; (no closing tag)
+- A tag that could have content, but doesn't: &lt;foo&gt;&lt;/foo&gt;
+
+## Known Issues (Or, Things We Designed Against the Spec)
+
+Please check the issue queue for a full list, but the following are
+issues known issues that are not presently on the roadmap:
+
+- Namespaces: HTML5 only [supports a selected list of namespaces](http://www.w3.org/TR/html5/infrastructure.html#namespaces)
+  and they do not operate in the same way as XML namespaces. A `:` has no special
+  meaning.
+  By default the parser does not support XML style namespaces via `:`;
+  to enable the XML namespaces see the  [XML Namespaces section](#xml-namespaces)
+- Scripts: This parser does not contain a JavaScript or a CSS
+  interpreter. While one may be supplied, not all features will be
+  supported.
+- Reentrance: The current parser is not re-entrant. (Thus you can't pause
+  the parser to modify the HTML string mid-parse.)
+- Validation: The current tree builder is **not** a validating parser.
+  While it will correct some HTML, it does not check that the HTML
+  conforms to the standard. (Should you wish, you can build a validating
+  parser by extending DOMTree or building your own EventHandler
+  implementation.)
+  * There is limited support for insertion modes.
+  * Some autocorrection is done automatically.
+  * Per the spec, many legacy tags are admitted and correctly handled,
+    even though they are technically not part of HTML5.
+- Attribute names and values: Due to the implementation details of the
+  PHP implementation of DOM, attribute names that do not follow the
+  XML 1.0 standard are not inserted into the DOM. (Effectively, they
+  are ignored.) If you've got a clever fix for this, jump in!
+- Processor Instructions: The HTML5 spec does not allow processor
+  instructions. We do. Since this is a server-side library, we think
+  this is useful. And that means, dear reader, that in some cases you
+  can parse the HTML from a mixed PHP/HTML document. This, however,
+  is an incidental feature, not a core feature.
+- HTML manifests: Unsupported.
+- PLAINTEXT: Unsupported.
+- Adoption Agency Algorithm: Not yet implemented. (8.2.5.4.7)
+
+## XML Namespaces
+
+To use XML style namespaces you have to configure well the main `HTML5` instance.
+
+```php
+use Masterminds\HTML5;
+$html = new HTML5(array(
+    "xmlNamespaces" => true
+));
+
+$dom = $html->loadHTML('<t:tag xmlns:t="http://www.example.com"/>');
+
+$dom->documentElement->namespaceURI; // http://www.example.com
+
+```
+
+You can also add some default prefixes that will not require the namespace declaration,
+but its elements will be namespaced.
+
+```php
+use Masterminds\HTML5;
+$html = new HTML5(array(
+    "implicitNamespaces"=>array(
+        "t"=>"http://www.example.com"
+    )
+));
+
+$dom = $html->loadHTML('<t:tag/>');
+
+$dom->documentElement->namespaceURI; // http://www.example.com
+
+```
+
+## Thanks to...
+
+The dedicated (and patient) contributors of patches small and large,
+who have already made this library better.See the CREDITS file for
+a list of contributors.
+
+We owe a huge debt of gratitude to the original authors of html5lib.
+
+While not much of the original parser remains, we learned a lot from
+reading the html5lib library. And some pieces remain here. In
+particular, much of the UTF-8 and Unicode handling is derived from the
+html5lib project.

+# The Parser Model
+
+The parser model here follows the model in section
+[8.2.1](http://www.w3.org/TR/2012/CR-html5-20121217/syntax.html#parsing)
+of the HTML5 specification, though we do not assume a networking layer.
+
+     [ InputStream ]    // Generic support for reading input.
+           ||
+      [ Scanner ]       // Breaks down the stream into characters.
+           ||
+     [ Tokenizer ]      // Groups characters into syntactic
+           ||
+    [ Tree Builder ]    // Organizes units into a tree of objects
+           ||
+     [ DOM Document ]     // The final state of the parsed document.
+
+
+## InputStream
+
+This is an interface with at least two concrete implementations:
+
+- StringInputStream: Reads an HTML5 string.
+- FileInputStream: Reads an HTML5 file.
+
+## Scanner
+
+This is a mechanical piece of the parser.
+
+## Tokenizer
+
+This follows section 8.4 of the HTML5 spec. It is (roughly) a recursive
+descent parser. (Though there are plenty of optimizations that are less
+than purely functional.
+
+## EventHandler and DOMTree
+
+EventHandler is the interface for tree builders. Since not all
+implementations will necessarily build trees, we've chosen a more
+generic name.
+
+The event handler emits tokens during tokenization.
+
+The DOMTree is an event handler that builds a DOM tree. The output of
+the DOMTree builder is a DOMDocument.
+
+## DOMDocument
+
+PHP has a DOMDocument class built-in (technically, it's part of libxml.)
+We use that, thus rendering the output of this process compatible with
+SimpleXML, QueryPath, and many other XML/HTML processing tools.
+
+For cases where the HTML5 is a fragment of a HTML5 document a
+DOMDocumentFragment is returned instead. This is another built-in class.

+## HTML5 Class
+
+Provides the top level interface for saving.
+
+## The Traverser
+
+Walks the DOM finding each element and passing it off to the output rules to
+convert to HTML5.
+
+## Output Rules
+
+The output rules are defined in the RulesInterface which can have multiple
+implementations. Currently, the OutputRules is the default implementation that
+converts a DOM as is into HTML5.
+
+## HTML5 String
+
+The output of the process it HTML5 as a string or saved to a file.
