+# JSON-path
+
+JSON-path is a simple JSON path parser and evaluator for PHP. It is based on the JSONPath 
+implementation in [Goessner's JSONPath](http://goessner.net/articles/JsonPath/). 
+The code allows you to parse json paths and evaluate them on php objects. Which makes it a query language for 
+php object structures.
+
+It's propably not the fastest solution to query php objects, but as the paths are stored as plain strings, it's
+easy to use them in configuration files or databases. This makes is a good solution for tools that need to query 
+a php object structure based on user input.
+
+## Installation
+
+The recommended way to install JSON-path is through [Composer](http://getcomposer.org).
+
+```bash
+  composer require phpdocumentor/json-path
+```
+
+## Usage
+
+```php  
+
+$parser = \phpDocumentor\JsonPath\Parser::createInstance();
+$query = $parser->parse('.store.book[*].author');
+
+$executor = new \phpDocumentor\JsonPath\Executor();
+foreach ($executor->execute($query, $json) as $result) {
+    var_dump($result);
+}
+
+```
