+# Simply Static
+
+Simply Static is a static site generator for WordPress that helps you create a static site that you can serve separately from your WordPress installation.
+
+This repository is a fork of version 2.1.0 of the Simply Static plugin found in the WordPress Subversion repository.
+
+## Why did we fork the plugin
+
+The original plugin is not compatible with PHP 7.3. This fork will support it.
