 ### Introduction: ###
 This library allows you reading SDM module(s) using:
 - [x] Hardware Serial (<i><b>recommended option</b>, smallest number of reads errors, especially for esp8266</i>) <b><i>or</i></b>
-- [x] Software Serial, attached as core libraries for esp8266 and avr</br>
+- [x] Software Serial, attached as core libraries for ESP8266 and AVR or as external lib for ESP32</br>
      (<i>the new version of esp Software Serial library</br>
       has a different initialization compared to avr!</br>
-      <b>This version of SDM library (>=2.0.8) works only with esp Software Serial 6.0.0 or higher!!!</b></br>
+      <b>This version of SDM library (>=2.2.2) works only with esp Software Serial 8.0.1 or higher!!!</b></br>
       If you have an older esp Software Serial version</br>
       then use other SDM library, details below the Credits section</i>)</br>
