+# Drogon Examples
+
+The following examples can help you understand how to use Drogon:
+
+1. [benchmark](https://github.com/an-tao/drogon/tree/master/examples/benchmark) - Basic benchmark example. see [wiki benchmarks](https://github.com/an-tao/drogon/wiki/13-Benchmarks)
+2. [client_example](https://github.com/an-tao/drogon/tree/master/examples/client_example/main.cc) - A client example.
+3. [simple_example](https://github.com/an-tao/drogon/tree/master/examples/simple_example) - A simple example showing how to create a web application using Drogon.
+4. [simple_example_test](https://github.com/an-tao/drogon/tree/master/examples/simple_example_test) - Some tests for the `simple_example`.
+
+### [TechEmpower Framework Benchmarks](https://github.com/TechEmpower/FrameworkBenchmarks) test suite
+
+I created a benchmark suite for the `tfb`, see [here](https://github.com/TechEmpower/FrameworkBenchmarks/tree/master/frameworks/C%2B%2B/drogon) for details.
