 # CSESoc Website
 
-## How to run locally
-- Install dependencies with `npm install`
-- Run using `npm run dev`
+This repository contains the code for a redesigned CSESoc website. The current website can be found at [csesoc.unsw.edu.au](https://csesoc.unsw.edu.au/).
+
+## How to run locally (without Docker, development mode)
+
+### Running the frontend
+
+1. Navigate to the `frontend` directory with `cd frontend`.
+2. Install dependencies with `npm install` if you haven't already.
+3. Run using `npm run dev`, changes will be reflected live.
+
+See `package.json` for further commands to lint, build, etc.
+
+### Running the backend
+
+1. Navigate to the `backend` directory with `cd backend`.
+2. Install dependencies with `npm install` if you haven't already.
+3. Run using `npm run dev`, changes will be reflected live.
+
+## How to run locally (with Docker, production mode)
+
+Make sure you have [Docker](https://docs.docker.com/get-docker/) installed.
+
+1. Run `docker-compose up` (or `docker-compose up -d` to run in the background) in the root directory, this will start the frontend and backend services. Note this may be a little slow the first time you run this command. This will build both the frontend and backend services in production mode, meaning live changes will not be reflected.
+2. Run `docker-compose down` to stop the services.
