+Important
+----
+This branch of Yasumi reflects the code up until version 1.8. With the release of Yasumi version 2.0, support for PHP 5 has ended. This code base serves as a support branch and will only receive the most critical bug fixes. Please note that v1.8.x works both in PHP 5 and PHP 7, but the code base hasn't been upgraded to PHP 7. 
 
+It is highly recommended to upgrade to PHP7 and Yasumi v2.0.0 to enjoy the latest changes and improvements. More information can be found here: [Yasumi Release v2](https://azuyalabs.github.io/yasumi/blog/release_v2)

+Introduction
+------------
 Yasumi (Japanese for 'Holiday'「休み」) is an easy PHP library to help you calculate the dates and names of holidays and other
 special celebrations from various countries/states. Many services exist on the internet that provide holidays, however
 are either not free or offer only limited information. In addition, no complete PHP library seems to exist today
