+## HOWTO Install esp32-s2 core for ESP32-S2 (Saola, AI-Thinker ESP-12K) boards into Arduino IDE
+
+
+These are instructions demonstrating the steps to install esp32-s2 core on Ubuntu machines. For Windows or other OS'es, just follow the the similar principles and steps.
+
+Assuming you already installed Arduino IDE ESP32 core and the installed directory is
+
+`/home/your_account/.arduino15/packages/esp32`
+
+
+### 1. Save the original esp32 core
+
+First, copy the whole original esp32 core to another safe place. Then delete all the sub-directories of
+
+`/home/your_account/.arduino15/packages/esp32/hardware/esp32/1.0.4`
+
+---
+
+### 2. Download esp32-s2 core
+
+#### 2.1 Download zip
+
+Download [**esp32-s2 core**](https://github.com/espressif/arduino-esp32/tree/esp32s2) in the `zip` format: 
+
+`arduino-esp32-esp32s2.zip`
+
+#### 2.2 Unzip
+
+<p align="center">
+    <img src="https://github.com/khoih-prog/AsyncHTTPRequest_Generic/blob/master/Images/esp32_s2_Core_Unzipped.png">
+</p>
+
+#### 2.3 Update esp32-s2 core directories
+
+Copy all subdirectories of esp32-s2 core into `/home/your_account/.arduino15/packages/esp32/hardware/esp32/1.0.4`
+
+---
+
+### 3 Download tools
+
+
+#### 3.1 Download Toolchain for Xtensa (ESP32-S2) based on GCC
+
+Download [**esp32-s2 Toolchain**](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/api-guides/tools/idf-tools.html#xtensa-esp32s2-elf) corresponding to your environment (linux-amd64, win64, etc.).
+
+For example `xtensa-esp32s2-elf-gcc8_4_0-esp-2020r3-linux-amd64.tar.gz`, then un-archive.
+
+
+<p align="center">
+    <img src="https://github.com/khoih-prog/AsyncHTTPRequest_Generic/blob/master/Images/esp32_s2_Toolchain.png">
+</p>
+
+#### 3.2 Download esptool
+
+
+Download [esptool](https://github.com/espressif/esptool/releases) int the `zip` format:
+
+`esptool-3.0.zip`
+
+#### 3.3 Unzip
+
+<p align="center">
+    <img src="https://github.com/khoih-prog/AsyncHTTPRequest_Generic/blob/master/Images/esp32_s2_esptool.png">
+</p>
+
+---
+
+### 4. Update tools
+
+#### 4.1 Update Toolchain
+
+Copy whole `xtensa-esp32s2-elf` directory into `/home/your_account/.arduino15/packages/esp32/hardware/esp32/1.0.4/tools`
+
+
+#### 4.2 Update esptool
+
+Rename `esptool-3.0` directory to `esptool`
+
+
+Copy whole `esptool` directory into `/home/your_account/.arduino15/packages/esp32/hardware/esp32/1.0.4/tools`
+
+
+<p align="center">
+    <img src="https://github.com/khoih-prog/AsyncHTTPRequest_Generic/blob/master/Images/esp32_s2_tools.png">
+</p>
+
+
+### 5. esp32-s2 WebServer Library Patch
+
+If you haven't installed a new version with [WebServer.handleClient delay PR #4350](https://github.com/espressif/arduino-esp32/pull/4350) or haven't applied the above mentioned PR, you have to use the following patch.
+
+
+**To be able to run Config Portal on ESP32-S2 boards**, you have to copy the files in [esp32-s2 WebServer Patch](esp32s2_WebServer_Patch/) directory into esp32-s2 WebServer library directory (~/.arduino15/packages/esp32/hardware/esp32/1.0.4/libraries/WebServer).
+
+Supposing the esp32-s2 version is 1.0.4, these files `WebServer.h/cpp` must be copied into the directory to replace:
+
+- `~/.arduino15/packages/esp32/hardware/esp32/1.0.4/libraries/WebServer/src/WebServer.h`
+- `~/.arduino15/packages/esp32/hardware/esp32/1.0.4/libraries/WebServer/src/WebServer.cpp`
+
+
+---
+
+That's it. You're now ready to compile and test for ESP32-S2 now
+
+---
+---
+
+### Note for Platform IO using ESP32 LittleFS
+
+In Platform IO, to fix the error when using [`LittleFS_esp32 v1.0`](https://github.com/lorol/LITTLEFS) for ESP32-based boards with ESP32 core v1.0.4- (ESP-IDF v3.2-), uncomment the following line
+
+from
+
+```
+//#define CONFIG_LITTLEFS_FOR_IDF_3_2   /* For old IDF - like in release 1.0.4 */
+```
+
+to
+
+```
+#define CONFIG_LITTLEFS_FOR_IDF_3_2   /* For old IDF - like in release 1.0.4 */
+```
+
+It's advisable to use the latest [`LittleFS_esp32 v1.0.5+`](https://github.com/lorol/LITTLEFS) to avoid the issue.
+
+Thanks to [Roshan](https://github.com/solroshan) to report the issue in [Error esp_littlefs.c 'utime_p'](https://github.com/khoih-prog/ESPAsync_WiFiManager/issues/28)

 ### HOWTO Fix `Multiple Definitions` Linker Error

 The current library implementation, using xyz-Impl.h instead of standard xyz.cpp, possibly creates certain `Multiple Definitions` Linker error in certain use cases. Although it's simple to just modify several lines of code, either in the library or in the application, the library is adding a separate source directory, named src_cpp, besides the standard src directory.
