 App available on: `http://0.0.0.0:8080`.  
+
+
+## Production deployment
+Prerequisite: machine with free ports 80 and 8084.  
+
+
+### Database
+Either build the database from scratch (lenghty process) using above instructions or just migrate the database from the faculty server (recommended).  
+
+TODO: build my-mongo
+
+
+### Backend
+Set database connection details in `/src/backend_flask/db_config.py`.  
+```
+mongodb://valuser:valuserpass@127.0.0.1:27017/valdb
+```
+In the above line, replace `valuser` with the username and `valuserpass` with the password that was used to create the database tables (the values were set in the root Makefile).  
+
+You can also set the number of workers in `/src/backend_flask/entrypoint.sh`.  
+In line with `gunicorn -t 4 -b 127.0.0.1:8084 app:app`, edit the `-t` parameter.  
+Rule of thumb is 2x number of available CPU cores.  
+
+Build the backend container:
+```bash
+# From git root
+$ make build-backend-flask
+```
+
+### Frontend
+Set the server address (where backend will be runnig) in `src/frontend_vue/config/config_prod.json`.  
+Build the `/dist` folder that contains the static app (we will be using Nginx to serve it).  
+```bash
+# From git root
+$ make build-frontend-prod
+```
+
+All set, now run the stack.  
+```bash
+# From git root
+$ make deploy-prod-stack
+```
