+# CBOR Example
+(See the README.md file in the upper level 'examples' directory for more information about examples.)
+
+## Overview
+
+The [CBOR](https://en.wikipedia.org/wiki/CBOR)(Concise Binary Object Representation) is a binary data serialization format which is similar to JSON but with smaller footprint. This example will illustrate how to encode and decode CBOR data using the APIs provided by [tinycbor](https://github.com/intel/tinycbor).
+
+For detailed information about how CBOR encoding and decoding works, please refer to [REF7049](https://tools.ietf.org/html/rfc7049) or [cbor.io](http://cbor.io/);
+
+## How to use example
+
+### Hardware Required
+
+This example should be able to run on any commonly available ESP32 development board.
+
+### Build and Flash
+
+Run `idf.py -p PORT flash monitor` to build and flash the project.
+
+(To exit the serial monitor, type ``Ctrl-]``.)
+
+See the [Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html) for full steps to configure and use ESP-IDF to build projects.
+
+## Example Output
+
+```bash
+I (320) example: encoded buffer size 67
