+=== PayU EU Payment Gateway for WooCommerce ===
+Contributors: payusa
+Tags: PayU, payment, payment gateway, platnosci, PayU Poland, PayU EU
+Requires at least: 4.4
+Tested up to: 6.4.1
+Stable tag: 2.0.32
+Requires PHP: 7.0
+License: Apache License 2.0
+
+== Description ==
+**PayU payment module for WooCommerce**
+
+The plugin offers the following payment methods:
+
+* PayU - standard - payer will be redirected to PayU's hosted payment page where any available payment type configured on your POS can be chosen
+* PayU - bank list - payment type list will be displayed, depending on chosen type the payer will be either redirected directly to the bank or to PayU's hosted payment page
+* PayU - payment card - payer will be redirected to PayU's hosted card form where credit, debit or prepaid card data can be securely entered
+* PayU - secure form - a secure form collecting credit, debit or prepaid card data will be displayed
+* PayU - Blik - payer will be redirected to Blik's page
+* PayU - installments - payer will be redirected to installment payment form
+* PayU - PayPo - payer will be redirected to PayPo payment form
+* PayU - Twisto - payer will be redirected to Twisto payment form
+
+Detailed information about each method and its configuration [can be found here](https://github.com/PayU-EMEA/woo-payu-payment-gateway).
+
+== Installation ==
+If you have any questions or would like to raise an issue please contact [our technical support](https://www.payu.pl/pomoc).
+
+= Minimum Requirements =
+PayU merchant account - if you do not have an account you can [**register a production account**](https://poland.payu.com/en/how-to-activate-payu/) or [**register a sandbox account**](https://registration-merch-prod.snd.payu.com/boarding/#/registerSandbox/?lang=en)
+
+**Note:** Module works only with `REST API` POS type (POS type is configured in PayU merchant panel after you register).
+
+Following PHP libraries are required: cURL i hash.
+
+= Automatic installation =
+Use [automatic installation and activation](https://wordpress.org/support/article/managing-plugins/#automatic-plugin-installation) available in Wordpress admin panel. Module name is `PayU EU Payment Gateway for WooCommerce`.
+
+= Updating =
+Upon plugin update from version 1.X to version 2.X the existing config data will be automatically converted.
+
+== Frequently Asked Questions ==
+
+= Does this load external javascript resources ? =
+
+Yes, it does.
+* For card payment we used [PayU Secure Form](https://developers.payu.com/en/card_tokenization.html#secureform) and for proper working it is necessary to load Secure Form JS SDK from the secure.payu.com domain. As a result, you do not need to have PCI DSS, PayU does it for you.
+* For presenting minimal installment amount we used [Widget Installments](https://developers.payu.com/en/installments.html#installments_best_practices_mini) and plugin loads the script from the static.payu.com domain.
+
+== Changelog ==
+= 2.0.32 =
+* Fixed php notices
+* Fixed getTotal for min/max
+= 2.0.31 =
+* Fixed warnings
+* SDK update
+= 2.0.30 =
+* Removed use of the NumberUtil class
