 ### Running the app (Locally/Debugging Purposes)
 
-#### Mongo and Redis Setup
+1. Run `yarn install` in the `client` and `server` directories.
+1. Run `docker compose -f docker-compose.yml -f docker-compose.dev.yml up -V --build` to start the development containers. The client will be running on http://localhost:5050 and the server will be listening on port 5001. Editing files should work as expected.
 
-1. Open the `docker-compose.yml` file and comment out all services except `caching` and `mongodb`
-
-2. Running Redis and Mongo
-
-```
-docker-compose up --build -d
-```
-
-#### Client Setup
-
-1. Setting up the client `.env` file (Placed in the root of your `client` folder)
-
-```
-REACT_APP_BACKEND_URL="http://localhost:3001"
-```
-
-2. Setting up `axios.ts`
-
-> Note: Since we're running poll voting app locally, we'll need to provide some extra information that normally Shibboleth would provide to us.
-
-> Your `axios.ts` file should look like the following:
-
-```
-export const instance = axios.create({
-  headers: { utorid: "utorid" },
-  baseURL: `${process.env.REACT_APP_BACKEND_URL}`,
-});
-```
-
-3. Setting up `socket.ts`
-
-> Note: Since we're running poll voting app locally, we'll need to provide some extra information that normally Shibboleth would provide to us.
-
-> Your `socket.ts` file should look like the following:
-
-```
-export const socket = io(`${process.env.REACT_APP_BACKEND_URL}`, {
-  withCredentials: true,
-  extraHeaders: { utorid: "utorid" }
-});
-```
-
-4. Running the client
-
-```
-yarn run start
-```
-
-#### Server Setup 
-
-1. Add instructor Utorid's to your whitelist file. It should be placed at the root of the `server` folder.
-
-> Your whitelist file should be named "whitelist" and should look like the following...
-
-```
-utorid1
-utorid2
-utorid3
-...
-```
-
-2. Setting up the server `.env` file (Placed in the root of your `server` folder)
-
-```
-PPORT=3001
-MONGODB_URL="mongodb://localhost:27018/quiz"
-FRONTEND_URL="http://localhost:3000"
-REDIS_URL="redis://default:password@localhost:6379"
-WHITELIST=../whitelist
-```
-
-3. Running the server
-
-```
-yarn run start
-```
-
-The client and server will be listening and serving on port `3000` and `3001` respectively.
+When the app runs in dev, all of the same containers used in production are used,
+plus an extra Apache container that simulates the production proxy running Shibboleth.
