+# Matomo Analytics & Tag Manager for WordPress
+
+## Code Status
+
+[![Build Status](https://travis-ci.org/matomo-org/wp-matomo.svg?branch=master)](https://travis-ci.org/matomo-org/wp-matomo/branches)
+
+## Description
+
+A hassle-free and cost-free web analytics platform for your WordPress which lets you stay in full control with 100% data ownership and user-privacy protection.
+
+This plugin installs a fully functional [Matomo](https://matomo.org) within your WordPress. If you already have a working Matomo (either [On-Premise](https://matomo.org/matomo-on-premise/) or [Matomo Cloud](https://matomo.org/hosting/)), use the [WP-Matomo Integration plugin](https://wordpress.org/plugins/wp-piwik/) instead. If you have a high traffic website, we recommend using On-Premise or the Cloud-hosted solution for better performance.
+
+Learn more about this plugin in the [readme.txt](readme.txt).
