 This library is based on, modified, bug-fixed and improved from [`DataCute`](https://github.com/datacute/DoubleResetDetector) to add support for ESP32.
 
 Using this library to detect a double reset, using
 
 1. RTC Memory, EEPROM or SPIFFS for ESP8266
 2. EEPROM and SPIFFS for ESP32.
 
-It is tested and working with 
-1. [`ESP8266 Core 2.6.2 or newer`](https://github.com/esp8266/Arduino)
-2. [`ESP32 Core 1.0.4 or newer`](https://github.com/espressif/arduino-esp32)
+## Prerequisite
+1. [`Arduino IDE 1.8.12 or later` for Arduino](https://www.arduino.cc/en/Main/Software)
+2. [`ESP32 core 1.0.4 or later`](https://github.com/espressif/arduino-esp32/releases) for ESP32 (Use Arduino Board Manager)
+3. [`ESP8266 core 2.6.3 or later`](https://github.com/esp8266/Arduino/releases) for ES82662 (Use Arduino Board Manager)
 
 ### Quick Start
 
-#### Use Arduino Library Manager
+#### Installing use Arduino Library Manager
 
-The easiest way is to use `Arduino Library Manager`. Search for `ESP_DoubleResetDetector`, then select / install the latest version.

- * This example will open a configuration portal when the reset button is pressed twice. 
- * This method works well on Wemos boards which have a single reset button on board. It avoids using a pin for launching the configuration portal.
- *
- * How It Works
- * 1) ESP8266
- * Save data in RTC memory, EPPROM or SPIFFS
- * 2) ESP32
- * Save data in 
- * a) EEPROM from address 256, size 512 bytes (both configurable)
- * b) SPIFFS, file name "/drd.dat"
- * 
- * So when the device starts up it checks this region of ram for a flag to see if it has been recently reset. 
- * If so it launches a configuration portal, if not it sets the reset flag. After running for a while this flag is cleared so that 
- * it will only launch the configuration portal in response to closely spaced resets.
- *
- * Settings
- * There are two values to be set in the sketch.
- *
- * DRD_TIMEOUT - Number of seconds to wait for the second reset. Set to 10 in the example.
- * DRD_ADDRESS - The address in ESP8266 RTC RAM to store the flag. This memory must not be used for other purposes in the same sketch. Set to 0 in the example.
