+## Installation
+`composer require nanuc/js-snippets`
+
+Publish config (optionally): 
+`php artisan vendor:publish --provider="Nanuc\JSSnippets\JSSnippetsServiceProvider" --tag=config`
+
+
+## Usage
+```
+<x-js-snippet>
+    <script>
+        console.log('Hello');
+        console.log('I will');
+        console.log('get minified');
+        console.log('and downloaded as a plain Javascript file');
+    </script>
+</x-js-snippet>
+```
+
+Scripts in the `js-snippet` component will get minified (thanks to https://github.com/tedious/JShrink) and loaded as separate Javascript source.
+
+## Behind the scenes
+The component will minify its content and put it in a file in the view cache. 
+It will also generate a key based on the content.
+
+Then it will create a script tag with a link that downloads this file as a plain Javascript source.
