+
+Library which converts HTML to [Markdown](http://daringfireball.net/projects/markdown/) for your sanity and convenience.
+
+
+**Requires**: PHP 5.3+
+
+**Lead Developer**: [@colinodell](http://twitter.com/colinodell)
+
+**Original Author**: [@nickcernis](http://twitter.com/nickcernis)
+
+
+### Why convert HTML to Markdown?
+
+*"What alchemy is this?"* you mutter. *"I can see why you'd convert [Markdown to HTML](https://github.com/thephpleague/commonmark),"* you continue, already labouring the question somewhat, *"but why go the other way?"*
+
+Typically you would convert HTML to Markdown if:
+
+1. You have an existing HTML document that needs to be edited by people with good taste.
+2. You want to store new content in HTML format but edit it as Markdown.
+3. You want to convert HTML email to plain text email. 
+4. You know a guy who's been converting HTML to Markdown for years, and now he can speak Elvish. You'd quite like to be able to speak Elvish.
+5. You just really like Markdown.
+
+### How to use it
+
+Require the library by issuing this command:
+
+```bash
+composer require league/html-to-markdown
+```
+
+Add `require 'vendor/autoload.php';` to the top of your script.
+
+Next, create a new HtmlConverter instance, passing in your valid HTML code to its `convert()` function:
+
+```php
+use League\HTMLToMarkdown\HtmlConverter;
+
+$converter = new HtmlConverter();
+
+$html = "
Quick, to the Batpoles!
";
+$markdown = $converter->convert($html);
+```
+
+The `$markdown` variable now contains the Markdown version of your HTML as a string:
+
+```php
+echo $markdown; // ==> ### Quick, to the Batpoles!
+```
+
+The included `demo` directory contains an HTML->Markdown conversion form to try out.
+
+### Conversion options
+
+By default, HTML To Markdown preserves HTML tags without Markdown equivalents, like `` and `
`.
+
+To strip HTML tags that don't have a Markdown equivalent while preserving the content inside them, set `strip_tags` to true, like this:
+
+```php
+$converter = new HtmlConverter(array('strip_tags' => true));
+
+$html = 'Turnips!';
+$markdown = $converter->convert($html); // $markdown now contains "Turnips!"
+```
+
+Or more explicitly, like this:
+
+```php
+$converter = new HtmlConverter();
+$converter->getConfig()->setOption('strip_tags', true);
+
+$html = 'Turnips!';
+$markdown = $converter->convert($html); // $markdown now contains "Turnips!"
+```
+
+Note that only the tags themselves are stripped, not the content they hold.
+
+To strip tags and their content, pass a space-separated list of tags in `remove_nodes`, like this:
+
+```php
+$converter = new HtmlConverter(array('remove_nodes' => 'span div'));
+
+$html = 'Turnips!
Monkeys!
';
+$markdown = $converter->convert($html); // $markdown now contains ""
+```
+
+### Style options
+
+Bold and italic tags are converted using the asterisk syntax by default. Change this to the underlined syntax using the `bold_style` and `italic_style` options.
+
+```php
+$converter = new HtmlConverter();
+$converter->getConfig()->setOption('italic_style', '_');
+$converter->getConfig()->setOption('bold_style', '__');
+
+$html = 'Italic and a bold';
+$markdown = $converter->convert($html); // $markdown now contains "_Italic_ and a __bold__"
+```
+
+### Line break options
+
+By default, `br` tags are converted to two spaces followed by a newline character as per [traditional Markdown](https://daringfireball.net/projects/markdown/syntax#p). Set `hard_break` to `true` to omit the two spaces, as per GitHub Flavored Markdown (GFM).
+
+```php
+$converter = new HtmlConverter();
+$html = '
test
line break
';
+
+$converter->getConfig()->setOption('hard_break', true);
+$markdown = $converter->convert($html); // $markdown now contains "test\nline break"
+
+$converter->getConfig()->setOption('hard_break', false); // default
+$markdown = $converter->convert($html); // $markdown now contains "test  \nline break"
+```
+
+### Passing custom Environment object
+
+You can pass current `Environment` object to customize i.e. which converters should be used.
+
+```php
+$environment = new Environment(array(
+    // your configuration here
+));
+$environment->addConverter(new HeaderConverter()); // optionally - add converter manually
+
+$converter = new HtmlConverter($environment);
+
+$html = '
Header

+
+';
+$markdown = $converter->convert($html); // $markdown now contains "### Header" and ""
+```
+
+### Limitations
+
+- Markdown Extra, MultiMarkdown and other variants aren't supported – just Markdown.
+
+### Known issues
+
+- Nested lists and lists containing multiple paragraphs aren't converted correctly.
+- Lists inside blockquotes aren't converted correctly.
+- Any reported [open issues here](https://github.com/thephpleague/html-to-markdown/issues?state=open).
+
+[Report your issue or request a feature here.](https://github.com/thephpleague/html-to-markdown/issues/new) Issues with patches or failing tests are especially welcome.
+
+### Style notes
+
+- Setext (underlined) headers are the default for H1 and H2. If you prefer the ATX style for H1 and H2 (# Header 1 and ## Header 2), set `header_style` to 'atx' in the options array when you instantiate the object:
+
+    `$converter = new HtmlConverter(array('header_style'=>'atx'));`
+
+     Headers of H3 priority and lower always use atx style.
+
+- Links and images are referenced inline. Footnote references (where image src and anchor href attributes are listed in the footnotes) are not used. 
+- Blockquotes aren't line wrapped – it makes the converted Markdown easier to edit.
+
+### Dependencies
+
+HTML To Markdown requires PHP's [xml](http://www.php.net/manual/en/xml.installation.php), [lib-xml](http://www.php.net/manual/en/libxml.installation.php), and [dom](http://www.php.net/manual/en/dom.installation.php) extensions, all of which are enabled by default on most distributions.
+
+Errors such as "Fatal error: Class 'DOMDocument' not found" on distributions such as CentOS that disable PHP's xml extension can be resolved by installing php-xml.
+
+### Contributors
+
+Many thanks to all [contributors](https://github.com/thephpleague/html-to-markdown/graphs/contributors) so far. Further improvements and feature suggestions are very welcome.
+
+### How it works
+
+HTML To Markdown creates a DOMDocument from the supplied HTML, walks through the tree, and converts each node to a text node containing the equivalent markdown, starting from the most deeply nested node and working inwards towards the root node.
+
+### To-do
+
+- Support for nested lists and lists inside blockquotes.
+- Offer an option to preserve tags as HTML if they contain attributes that can't be represented with Markdown (e.g. `style`).
+
+### Trying to convert Markdown to HTML?
+
+Use one of these great libraries:
+
+ - [league/commonmark](https://github.com/thephpleague/commonmark) (recommended)
+ - [cebe/markdown](https://github.com/cebe/markdown)
+ - [PHP Markdown](https://michelf.ca/projects/php-markdown/)
+ - [Parsedown](https://github.com/erusev/parsedown)
+
+No guarantees about the Elvish, though.
