 # qp-demo
+This is the component used in the [Quantum Package demo]( https://quantumpackage.github.io/qp2/page/try)
 
+- examples: Examples included with quantum package docker image.
+
+- Dockerfile: Create docker image from prebuild quantum package `quantum_package_static.tar.gz`. This is the image of Quantum Package demo
+
+- Dockerfile.compile: Create docker image from the [Quantum Package GitHub repo](https://github.com/QuantumPackage/qp2).
+
+- run.sh: run the image in the context of the demo. (With isolated network, a limited number of container and a time limit)
+
+## What is Docker
+Docker is a containerization software.
+For more info about it you can cosult the official [Docker documentation](https://docs.docker.com)
+
+## How to build the image
+
+### Precompiled
+
+run `make`
+
+A tar.gz archive of quantum package is needed at the root of the project with the name `quantum_package_static.tar.gz`
+
+This archive can be create with the command `qp_export_as_tgz` of quantum package
+
+### Compiled from github
+
+run `make compile`
+
+There is no guarantee of success because it's use the Quantum Package ./configure tool to install third party dependencies.
+
+## Before use run.sh
+
+We must run `make network`  before the first use of run.sh because it use a custom network bridge to disable communication between QP2 containers
