 ESP32/ESP8266 WebServer, WiFi manager and ACE web editor Arduino library. Based on [ESPAsyncWebServer](https://github.com/me-no-dev/ESPAsyncWebServer) from @me-no-dev
 
 This is the equivalent to [**esp-fs-webserver**](https://github.com/cotestatnt/esp-fs-webserver/) Arduino library, but working with the very good **ESPAsyncWebServer** library instead default webserver library.
-From some tests I have done, I have been able to observe that a webserver created with this library is much faster and more responsive, which is why I decided to develop this variant of the library.
 
 **Note**:
 Starting from version 2.0.0 ESP32 core for Arduino introduced the LittlsFS library like ESP8266. The examples in this library is written to work with this for both platform by default. Change according to your needs if you prefer other filesystems.

 In the image below, for example, the HTML and Javascript code to provision the devices in the well-known [ThingsBoard IoT platform](https://thingsboard.io/) has been added at runtime starting from the Arduino sketch (check example [customHTML.ino](https://github.com/cotestatnt/async-esp-fs-webserver/tree/main/examples/customHTML)).

+In addition to built-in firmware update functionality, you can also upload your web server content all at once (typically the files are placed inside the folder `data` of your sketch).
