-Simple HTTP server
-------------------
+# Simple HTTP/HTTPS server
 
-This is a very minimal HTTP server I use in some of the projects.
+This is a very minimal HTTP server. Optionally supports HTTPS server based on mbedTLS server example. 
 
-Absolutely not ready for any kind of production use.
-
-How to use
-----------
-
-Really, please see above note.
+# How to use
 
 This directory is an ESP-IDF component. Clone it (or add it as a submodule) into the component directory of the project.
+Enable TLS/SSL HTTPS server by uncommenting the `#define HTTPS_SERVER` line at `https_server.h`, otherwise it will implement unsecured http server. Server certificate and private key are loaded at `https_server.c` directly into flash code as in the [`open_ssl_server`](https://github.com/espressif/esp-idf/tree/master/examples/protocols/openssl_server) example from ESP-IDF repository. Don't forget to insert [`cacert.pem`](https://github.com/espressif/esp-idf/blob/master/examples/protocols/openssl_server/main/cacert.pem) and [`prvtkey.pem`](https://github.com/espressif/esp-idf/blob/master/examples/protocols/openssl_server/main/prvtkey.pem) at your main application directory if you want to run GET/POST examples.

 None yet, but I tried to make the comments in the header file helpful.
 
+# Examples
 
-Example
--------
+Examples functions at http server:
 
-None yet.
+## GET Method Example
+
+`simple_GET_method_example()` function:
 
+* Add http_server.c and http_server.h as a component into your project.
+* Server initialization added into the example function, simply call it and it should work!
+* Receiving a GET request at /, http server response is a "Hello World, from ESP32!" html.
 
-Debugging
----------
+## POST Method Example
+`simple_POST_method_example()` function:
+* As well as GET example, simply add http_server as a componente into your ESP-IDF project.
+* Server initialization added into the POST example function, simply call it and don't worry.
+* Post to / a pair of key-value where the key is 'key' and value some value you want to test. The example will show value content. If needed, increade log verbosity at `make menuconfig` to show all parsed key-value pairs.
 
-Increasing log level to "Verbose" should produce lots of output related to request handling.
