Improve README and docker compose files (#43)

* Split compose file into two * Split `docker-compose.yml` into `compose.yml` and `compose.dev.yml` * Ensure all containers restart * Unmount volumes for base `compose.yml` * Publish backend service ports only for `compose.dev.yml` * Configure backend services to have both "start" and "dev" scripts * Standardise port numbers * Ensure correct dev command * Skip mongo startup messages * README: Improve clarity * Fix typo * Compose: Fix ports * Ensure backend services can communicate * Remove useless networks * Due to the lack of API gateway, all backend services currently need to be exposed directly for now.

 ### Note: 
 - You can choose to develop individual microservices within separate folders within this repository **OR** use individual repositories (all public) for each microservice. 
 - In the latter scenario, you should enable sub-modules on this GitHub classroom repository to manage the development/deployment **AND** add your mentor to the individual repositories as a collaborator. 
-- The teaching team should be given access to the repositories as we may require viewing the history of the repository in case of any disputes or disagreements.

+
+## Pre-requisites
+
+1. Install [Docker Desktop](https://www.docker.com/products/docker-desktop/)
+2. Clone the GitHub repository
+```
+git clone https://github.com/CS3219-AY2425S1/cs3219-ay2425s1-project-g03.git
+```
+
+## Getting Started
+
+**Step 1: Copy Environment Configuration File**
+
+To get started, copy the contents of `.env.sample` into a new `.env` file located at the root level of the project. 
+
+**Step 2: Build the Docker containers**
+
+Next, run the following command to build the Docker containers.
+
+```bash
+docker compose -f compose.yml build --no-cache
+```
+
+**Step 3: Start the Docker containers**
+
+Once the build is complete, you can start the Docker containers.
+
+```bash
+docker compose -f compose.yml up -d
+```
+
+After spinning up the services, you may access the frontend client at `127.0.0.1:4200`. Specifically, you can navigate to the Question SPA at `127.0.0.1:4200/questions` and the login page at `127.0.0.1/account`.
+
+If you would like to spin up the services in development mode, you may use the following command. This enables hot reloading and exposes the ports for all microservices.
+
+```bash
+docker compose -f compose.yml -f compose.dev.yml up -d
+```
+
+| Service               | Port |
+|-----------------------|------|
+| Frontend              | 4200 |
+| API Gateway           | 8080 |
+| Question Service      | 8081 |
+| User Service          | 8082 |
+| Match Service         | 8083 |
+| Collaboration Service | 8084 |
+| Chat Service          | 8085 |
+| History Service       | 8086 |
+
+
+**Step 4: Stop the Docker containers**
+
+Once you are done, stop and remove the containers using:
+
+```bash
+docker compose down -v
+```
+
+Note that this will clear any data stored in volumes associated with the containers. If you would like to keep your data, you can run the command without the `-v` flag, which will remove the containers but retain the data in the volumes for future use.
