 # Pharmacy Information Management System
 
-### Setup 
+## Setup
 
+The application is divided into a frontend and backend service. For an initial setup run `npm install` in both the frontend and backend subdirectories. This will install the dependencies required for each of the services.
 
-The application is divided into a frontend and backend service. For an initial setup you will need to `run npm install` in both the frontend and backend subdirectories.  This will install the dependencies required for each of the services. 
+## Running backend and frontend
 
-### Running 
+Run the individual services by either launching both of them independently or using pm2 innately through Docker.
 
-Running the individual services can be done by either launching both of them independently or using pm2. To run them individually you will need to open a terminal window in each of the frontend and backend subdirectories.  From there you will need to run `npm start` in each of the terminal windows.  
+### Running independently
 
-To run both the systems under pm2 you will first need to install it: `npm install pm2 -g`  After it is installed you can run both the systems with a single command `pm2 start pm2.config.json`.  This will start both the frontend and the backend services. 
+To run them individually you will need to open a terminal window in each of the frontend and backend subdirectories. From there you will need to run `npm start` in each of the terminal windows.
 
-By default, the frontend will start on port 3000 and the backend will start on port 5051.  To configure the frontend to start on different port set the PORT environment variable to the port you would like it to start on.  ex.  `PORT 5050 npm start`  To configure the backend to start on a different port set the BACKEND_PORT environment variable to the port you would like it to run on. 
+By default, the frontend will start on port 5050 (defined in `frontend/.env`) and the backend will start on port 5051 (defined in `backend/env.json`).
 
-These environment variables, and others , can also be set in the pm2 configuration file for the individula service entries. 
+To configure the frontend to start on different port, set the `PORT` environment variable to the desired port; e.g. `PORT=5050 npm start`, or create a `frontend/.env.local` to override `PORT`.
 
-Once running both the frontend and backend systems open [http://localhost:5050](http://localhost:5050) in your browser to view the application. 
+To configure the backend to start on a different port, set the `BACKEND_PORT` environment variable to the desired port; e.g.  
+`BACKEND_PORT=5051 npm start`.
+
+These environment variables, and others, can also be set in the pm2 configuration file for the individual service entries.
+
+Once running both the frontend and backend systems, open [http://localhost:5050](http://localhost:5050) in your browser to view the application.
+
+### Using pm2
+
+`pm2` is used in our [Dockerized REMS Integration Prototype setup](https://github.com/mcode/rems-setup/blob/main/DeveloperSetupGuide.md) for production to start both the frontend and the backend services. It is not used in development due to a bug with hot-reloading code changes in the two services.
 
 ## Version
-This application requires node v20.0 or greater.
+
+This application requires node.js v20.0 or greater. Using [`nvm`](https://github.com/nvm-sh/nvm) is optional, but easier when managing different node.js versions.
+
+- `nvm install 20`
+- `nvm use 20` or `nvm use default 20`, as most of the REMS Integration Prototype repositories are compatible with node v20.0.
