+## Node.js dependency
+
+### Debian
+
+To install Node.js, use the following commands to get version 20.x:  
+
+    $ curl -sL https://deb.nodesource.com/setup_20.x | sudo -E bash -
+    $ sudo apt-get install -y nodejs
+    
+This will install *npm* which will be used to build and start the application.
+
+Get the *node-gyp* tool:  
+
+    $ sudo npm install -g node-gyp
+
+The proxies must have been setup previously.
+
+To rebuild the addons, launch:  
+
+    $ ./node-gyp-electron.sh
+
+## Notes
+
+If you need to set the proxy at the ILL:  
+
+    $ npm config set proxy http://proxy.ill.fr:8888
+    $ npm config set https-proxy http://proxy.ill.fr:8888
+
+And use the proxy for installing node-gyp:
+
+    $ node-gyp configure --proxy=http://proxy.ill.fr:8888/
