+# IQParts/Content
+
+### Installation
+`composer require iqparts/content`
+
+### Content
+This library is a small wrapper around [League\Flysystem](https://github.com/thephpleague/flysystem).
+This library lets you do anything that Flysystem already can, but uses its own objects with some extra
+functions.
+
+### Resolver
+This library also includes an AssetResolver which returns a PSR-7 response if the file exists
+on the filesystem.
+
+### Usage
+``` php
+// Filesystem
+$fs = new IQParts\Content\Filesystem(
+    new League\Flysystem\AdapterInterface(),
+    new League\Flysystem\Config()
+);
+
+// AssetResolver
+$resolver = new AssetResolver($fs);
+
+if ($resolver->exists('my-file.txt') {
+    // PSR-7 $response
+    $response = $resolver->resolve(
+        $request,       // PSR-7 request
+        $response,      // PSR-7 response
+        $cacheControl   // CacheControl object,
+        $inline         // Inline or as attachment
+    );
+}
+
+// MimeDetector
+$mimetype = (new MimeDetector([
+    'my-mime' => 'my-mimetype'
+]))->detectFromExtension('document.pdf');
+$mimetype = 'application/pdf'
+
+```
