+
+Ex. I want to be able the stop the running pipeline by pressing a stop button. If the pipeline is stopped, I see a info-level message confirming it in the logger, if it fails the message should be displayed in red (error). Also, all the progress bars in the nodes must be set to 0. -->

+<!--
+A clear and concise description of what the feature requires.
+
+1. Play button turns into stop button when pipeline is running
+2. Stop button turns into play button when pipeline is finished
+3. Stop button turns into play button when pipeline is successfully stopped
+4. Logger displays messages everytime the play/stop button is pressed
+5. Progress bars are set to 0 when stopping pipeline
+6. Stop button has a Python interface -->

 ## Voilà Viewer
 Source code of the correspondng o²S²PARC Service that takes as input a Jupyter Notebook and it shows it using Jupyter [Voilà](https://github.com/voila-dashboards/voila)
+
+## How it works
+The Service waits for a `voila.ipynb` file in input_1, when it is found, in renders it with voila:
+
+
+![Voila_Viewer_v1](https://github.com/ITISFoundation/voila-viewer/assets/18575092/73d43e27-71d8-4733-bf20-32262a2e9824)
+
+## How to test
+
+### Locally
+
+```
+make build run-local # Then visit 127.0.0.1:8888 in your browser
+```
+A `voila.ipynb` has to be `added to validation/inputs/input_1`
+### In a local o²S²PARC deployment
+
+```
+make build publish-local
+```
+
+### In o²S²PARC
+Use the "Voila-viewer Example" template in master.
