+
+PhpSpreadsheet is a library written in pure PHP and offers a set of classes that
+allow you to read and write various spreadsheet file formats such as Excel and LibreOffice Calc.
+
+## Documentation
+
+Read more about it, including install instructions, in the [official documentation](https://phpspreadsheet.readthedocs.io). Or check out the [API documentation](https://phpoffice.github.io/PhpSpreadsheet).
+
+Please ask your support questions on [StackOverflow](https://stackoverflow.com/questions/tagged/phpspreadsheet), or have a quick chat on [Gitter](https://gitter.im/PHPOffice/PhpSpreadsheet).
+
+## PHPExcel vs PhpSpreadsheet ?
+
+PhpSpreadsheet is the next version of PHPExcel. It breaks compatibility to dramatically improve the code base quality (namespaces, PSR compliance, use of latest PHP language features, etc.).
+
+Because all efforts have shifted to PhpSpreadsheet, PHPExcel will no longer be maintained. All contributions for PHPExcel, patches and new features, should target PhpSpreadsheet `master` branch.
+
+Do you need to migrate? There is [an automated tool](/docs/topics/migration-from-PHPExcel.md) for that.
