+Docker container for EiffelWeb debug example with apache2+libfcgi.
+==================================================================
+
+This example demonstrates the use of EiffelWeb with Apache2, using the libfcgi connector.
+For that, it is using the Docker solution to show the compilation and configuration steps.
+
+To build the docker image:
+
+```
+	docker build -t local/ewf-debug-httpd .
+```
+
+To run the docker image in a self-destroyed container:
+```
+	docker run --rm -it -p 8080:80 --name my-ewf-debug local/ewf-debug-httpd
+```
+
+Notes:
+	- `--rm` : to remove the container after the execution
+	- `-p 8080:80` : to map internal listening port 80 to localhost port 8080.
+	- on Linux, you may need to use `sudo` to be able to use `docker`
+	- depending on the docker installation, you may need to add an extra `-e ISE_PLATFORM=linux-x86` to force execution in 32bits.
+	- This docker example is simple on purpose. For production it should be improved and optimized to keep the image smaller and more customizable.
+	- For more advanced Docker usage, please refer to official https://www.docker.com/ website.
