+
+For example, when an HTTP request is received, Mongoose created a
+`struct mg_http_message` which has a collection of `struct mg_str` pointing
+to request method, URI, headers, and so on. This way, Mongoose avoids
+any heap allocations and does not modify the received buffer - instead, it
+uses `struct mg_str` to describe various parts of HTTP request.

-# An example ESP32 application
-
-To build this application, follow these steps:
-
-1. Make sure you have Docker installed
-2. Clone whole mongoose repository on your machine:
-  ```sh
-  git clone --depth 1 https://github.com/cesanta/mongoose.git
-  ```
-3. Start command line or terminal, and go into the example's directory:
-  ```sh
-  cd mongoose/examples/esp32
-  ```
-4. Run `make`. This invokes a Docker-based build. A firmware will be built
-  in the `build/` directory:
-  ```sh
-  make
-  ```
-
-# Flashing built firmware
-
-If you have a real board to flash to, you can flash a built firmware.
-First, make sure to have `esptool.py` script installed on your workstation.
-Then, connect the board to your workstation and run the following command:
-
-```sh
-make flash COMPORT=YOUR_USB_PORT
-```

+        On devices with limited RAM, it is important to limit the response size
+        of API calls. This example demonstrates how to fetch a large
+        data in smaller chunks, and guarantee its integrity.
+        Data gets returned in a series of request/response transactions,
+        where each response is small enough to fit into available device RAM.
+        <br/><br/>
+        Data integrity is implemented by versioning.
+        The idea is that the first response includes the current "version" of the
+        data, and that version is passed to all subsequent requests.
+        If data version changes in the middle of the request series,
+        client fails with 'wrong version' error.
