-![Build Status](https://github.com/c4dt/service-stainless/actions/workflows/build.yml/badge.svg)
+# Stainless-ByzCoin Demonstrator has been Archived
+
+This repo has been archived and is only available to run the demo.
 
 # Stainless-ByzCoin Demonstrator
 
+The Stainless demonstrator shows how Stainless helps develop Smart Contracts free of errors. 
+It provides an interactive environment where the user can verify prewritten Smart Contracts, 
+deploy them on a blockchain, and call their functions.
+
+A first introductory scenario involves a Candy Shop that maintains its candy balance with a simple 
+Smart Contract, which prevents people from cheating by taking away more candies than are available. 
+A second scenario illustrates a bug in a Smart Contract that appeared on the Ethereum blockchain 
+a few years ago, and led to a controversial fork to prevent significant monetary loss. 
+It also explains how Stainless could have prevented it.
+
+Please refer to the [project's showcase](https://factory.c4dt.org/showcase/stainless-for-smart-contracts/presentation)
+for additional information on the project's theoretical background.
+
+## Running the Demo
+
 Steps to run locally:
 
-You first need to generate the node's configs
 ```
-make configs
+git clone https://github.com/c4dt/service-stainless
+cd service-stainless
+docker-compose up -d
+open localhost:8080
 ```
 
-If you want our prebuilt images
-```
-docker-compose pull
-```
-Else if you want to build the images yourself
-```
-make webapp-proto
-docker-compose build
-```
+The demo has instructions how to run it.
 
-Launch it with
-```
-docker-compose up
-```
+## Persistent data
+
+On the first run, pre-computed data is copied to your repo at [./backend/configs].
+It contains the state of the blockchain and some variables.
 
-And open a browser to http://localhost:80/stainless-demo/
+If you want to start over, you have to:
+- delete the [./backend/configs]
+- [remove the local storage](https://intercom.help/scoutpad/en/articles/3478364-how-to-clear-local-storage-of-web-browser) 
+from your browser
