+## Building for production
+A bundle has to be created of the project: `meteor npm run build` create a StyleExplorer.tar.gz file in the parent folder.
+This archive has to be shipped to the server. Eg via scp: `scp StyleExplorer.tar.gz [email protected]:/home/thibault/style_explorer`.
+
+After this you need to restart the node application with the new code.
+```
+ssh [email protected]
+pm2 stop main   # stop the previous app
+cd style_explorer
+rm -rf bundler      # remove the previous code
+tar -xzf StyleExplorer.tar.gz   # unpack bundle
+rm StyleExplorer.tar.gz     # remove archive (optional)
+cd bundle/programs/server
+npm install     # install node dependencies
+cd ~
+pm2 start main      # restart application
+```
