+# maml-php
+
+A modern, well‑tested implementation of the [MAML](https://maml.dev) data format for PHP.

+
+## Installation
+
+```
+composer require maml/maml
+```
+
+## Usage
+
+```php
+use Maml\Maml;
+
+$data = Maml::parse('{
+  project: "MAML"
+  tags: [
+    "minimal"
+    "readable"
+  ]
+
+  # A simple nested object
+  spec: {
+    version: 1
+    author: "Anton Medvedev"
+  }
+
+  notes: """
+This is a raw multiline string.
+Keeps formatting as‑is.
+"""
+}');
+
+echo $data['project']; // "MAML"
+
+$text = Maml::stringify(['foo' => 'bar', 'list' => [1, 2, 3]]);
