+
+*Hey, bro, please ★ the package for my motivation :)* 
+
+## Basic Usage
+```php
+$books = [
+    ['ISBN', 'title', 'author', 'publisher', 'ctry' ],
+    [618260307, 'The Hobbit', 'J. R. R. Tolkien', 'Houghton Mifflin', 'USA'],
+    [908606664, 'Slinky Malinki', 'Lynley Dodd', 'Mallinson Rendel', 'NZ']
+];
+$xlsx = SimpleXLSXGen::fromArray( $books );
+$xlsx->saveAs('books.xlsx');
+```
+![XLSX screenshot](books.png)
+```
+// SimpleXLSXGen::download() or SimpleXSLSXGen::downloadAs('table.xlsx');
+```
+
+## Installation
+The recommended way to install this library is [through Composer](https://getcomposer.org).
+[New to Composer?](https://getcomposer.org/doc/00-intro.md)
+
+This will install the latest supported version:
+```bash
+$ composer require shuchkin/simplexlsxgen
+```
+or download class [here](https://github.com/shuchkin/simplexlsxgen/blob/master/src/SimpleXLSXGen.php)
+
+## Examples
+### Data types
+```php
+$data = [
+    ['Integer', 123],
+    ['Float', 12.35],
+    ['Procent', '12%'],
+    ['Date','2020-05-20'],
+    ['Datetime', '2020-05-20 02:38:00'],
+    ['String', 'See SimpleXLSXGen column autosize feature']
+];
+SimpleXLSXGen::fromArray( $data )->saveAs('datatypes.xlsx');
+```
