 > **Note:** To run the examples (except for the _Self-Signed-Certificates_ example), you need to execute the script extras/create_cert.sh first (see [Issue #26](https://github.com/fhessel/esp32_https_server/issues/26) for Windows). This script will create a simple CA to sign certificates that are used with the examples. Some notes on the usage can be found in the extras/README.md file.

+You will find several examples showing how you can use the library:
 
 - [Static-Page](examples/Static-Page/Static-Page.ino): Short example showing how to serve some static resources with the server. You should start with this sketch and get familiar with it before having a look at the more complex examples.
 - [Parameters](examples/Parameters/Parameters.ino): Shows how you can access request parameters (the part after the question mark in the URL) or parameters in dynamic URLs (like /led/1, /led/2, ...)
-- [Parameter-Validation](examples/Parameter-Validation/Parameter-Validation.ino): Shows how you can integrate validator functions to do formal checks on parameters in your URL.
 - [Put-Post-Echo](examples/Put-Post-Echo/Put-Post-Echo.ino): Implements a simple echo service for PUT and POST requests that returns the request body as response body. Also shows how to differentiate between multiple HTTP methods for the same URL.
 - [HTTPS-and-HTTP](examples/HTTPS-and-HTTP/HTTPS-and-HTTP.ino): Shows how to serve resources via HTTP and HTTPS in parallel and how to check if the user is using a secure connection during request handling
-- [HTML-Forms](examples/HTML-Forms/HTML-Forms.ino): Shows how to use body parsers to handle requests created from HTML forms (access text field contents, handle file upload, etc.).
-- [Async-Server](examples/Async-Server/Async-Server.ino): Like the Static-Page example, but the server runs in a separate task on the ESP32, so you do not need to call the loop() function in your main sketch.
-- [Self-Signed-Certificate](examples/Self-Signed-Certificate/Self-Signed-Certificate.ino): Shows how to generate a self-signed certificate on the fly on the ESP when the sketch starts. You do not need to run `create_cert.sh` to use this example.
 - [Middleware](examples/Middleware/Middleware.ino): Shows how to use the middleware API for logging. Middleware functions are defined very similar to webservers like Express.
 - [Authentication](examples/Authentication/Authentication.ino): Implements a chain of two middleware functions to handle authentication and authorization using HTTP Basic Auth.
+- [Async-Server](examples/Async-Server/Async-Server.ino): Like the Static-Page example, but the server runs in a separate task on the ESP32, so you do not need to call the loop() function in your main sketch.
 - [Websocket-Chat](examples/Websocket-Chat/Websocket-Chat.ino): Provides a browser-based chat built on top of websockets. **Note:** Websockets are still under development!
+- [Parameter-Validation](examples/Parameter-Validation/Parameter-Validation.ino): Shows how you can integrate validator functions to do formal checks on parameters in your URL.
+- [Self-Signed-Certificate](examples/Self-Signed-Certificate/Self-Signed-Certificate.ino): Shows how to generate a self-signed certificate on the fly on the ESP when the sketch starts. You do not need to run `create_cert.sh` to use this example.
 - [REST-API](examples/REST-API/REST-API.ino): Uses [ArduinoJSON](https://arduinojson.org/) and [SPIFFS file upload](https://github.com/me-no-dev/arduino-esp32fs-plugin) to serve a small web interface that provides a REST API.
 
 If you encounter error messages that cert.h or private\_key.h are missing when running an example, make sure to run create\_cert.sh first (see Setup Instructions).

- * Example for the ESP32 HTTP(S) Webserver
- *
- * IMPORTANT NOTE:
- * This example is a bit more complex than the other ones, so be careful to 
- * follow all steps.
- * 
- * Make sure to check out the more basic examples like Static-Page to understand
- * the fundamental principles of the API before proceeding with this sketch.
- * 
- * To run this script, you need to
- *  1) Enter your WiFi SSID and PSK below this comment
- *  2) Install the SPIFFS File uploader into your Arduino IDE to be able to
- *     upload static data to the webserver.
- *     Follow the instructions at:
- *     https://github.com/me-no-dev/arduino-esp32fs-plugin
- *  3) Upload the static files from the data/ directory of the example to your
- *     module's SPIFFs by using "ESP32 Sketch Data Upload" from the tools menu.
- *     If you face any problems, read the description of the libraray mentioned
- *     above.
- *     Note: If mounting SPIFFS fails, the script will wait for a serial connection
- *     (open your serial monitor!) and ask if it should format the SPIFFS partition.
- *     You may need this before uploading the data
- *     Note: Make sure to select a partition layout that allows for SPIFFS in the
- *     boards menu
- *  4) Have the ArduinoJSON library installed and available. (Tested with Version 5.13.4)
- *     You'll find it at:
- *     https://arduinojson.org/
- *
- * This script will install an HTTPS Server on your ESP32 with the following
- * functionalities:
- *  - Serve static files from the SPIFFS's data/public directory
- *  - Provide a REST API at /api to receive the asynchronous http requests
- *    - /api/uptime provides access to the current system uptime
- *    - /api/events allows to register or delete events to turn PINs on/off
- *      at certain times.
- *  - Use Arduino JSON for body parsing and generation of responses.
- *  - The certificate is generated on first run and stored to the SPIFFS in
- *    the cert directory (so that the client cannot retrieve the private key)

+   Example for the WT32_ETH01 HTTP(S) Webserver
+

+   To run this script, your need to
+    1) Make sure to have certificate data available. You will find a
+       shell script (create_cert.sh) and instructions to do so in the library folder
+       under extras/
+
+   This script will install an HTTPS Server on your WT32_ETH01 with the following
+   functionalities:
+    - Show page on web server root that will display some SVG smileys.
+      Using a simple HTML form and GET parameters, you can change the colors
+      of those images.
+    - Provide the svg image with an optional GET parameter that allows to
+      modify the background color, URL: /images/awesome.svg
+    - Provide an example that shows how wildcard URL parameters get parsed
+      URL: /urlparam/some/thing
+    - 404 for everything else

+/**
+   Example for the WT32_ETH01 HTTP(S) Webserver
+
+   IMPORTANT NOTE:
+   This example is a bit more complex than the other ones, so be careful to
+   follow all steps.
+
+   Make sure to check out the more basic examples like Static-Page to understand
+   the fundamental principles of the API before proceeding with this sketch.
+
+   To run this script, you need to
+    1) Install the SPIFFS File uploader into your Arduino IDE to be able to
+       upload static data to the webserver.
+       Follow the instructions at:
+       https://github.com/me-no-dev/arduino-esp32fs-plugin
+    2) Upload the static files from the data/ directory of the example to your
+       module's SPIFFs by using "ESP32 Sketch Data Upload" from the tools menu.
+       If you face any problems, read the description of the libraray mentioned
+       above.
+       Note: If mounting SPIFFS fails, the script will wait for a serial connection
+       (open your serial monitor!) and ask if it should format the SPIFFS partition.
+       You may need this before uploading the data
+       Note: Make sure to select a partition layout that allows for SPIFFS in the
+       boards menu
+    4) Have the ArduinoJSON library installed and available. (Tested with Version 5.13.4)
+       You'll find it at:
+       https://arduinojson.org/
+
+   This script will install an HTTPS Server on your WT32_ETH01 with the following
+   functionalities:
+    - Serve static files from the SPIFFS's data/public directory
+    - Provide a REST API at /api to receive the asynchronous http requests
+      - /api/uptime provides access to the current system uptime
+      - /api/events allows to register or delete events to turn PINs on/off
+        at certain times.
+    - Use Arduino JSON for body parsing and generation of responses.
+    - The certificate is generated on first run and stored to the SPIFFS in
+      the cert directory (so that the client cannot retrieve the private key)

+    <h2>About This Example</h2>
+    <p>This example shows you a web-page that can be used to control GPIOs 25, 26, 27, 32 and 33 to be turned on or off at a given time.</p>
+    <p>For simplicity, we use the system uptime here, which you can see at the top of the page.</p>
+    <p>The page uses the REST API provided at /api to commuicate with the ESP32.</p>
+    <p><strong>GET /api/uptime</strong> returns the current system uptime:</p>
+    <pre>{"uptime":42}</pre>
+    <p>This node is polled every 10 seconds to stay synchronized.</p>
+    <p><strong>GET /api/events</strong> returns the current list of events:</p>
+    <pre>[{"gpio":27,"state":1,"time":42,"id":0}, ...]</pre>
+    <p>This node is polled every 60 seconds to stay synchronized</p>
+    <p><strong>POST /api/events</strong> can be used to add new events. The response object will contain an additional id that can be used to refer to the event.</p>
+    <p><strong>DELETE /api/events/<em>id</em></strong> will delete the event with the specified id. If events are executed (time &lt; uptime), they are deleted as well.</p>
+    <p>The client side javascript synchronizes your view even if not explicit request is sent to the ESP32.</p>
