-# Frontend Setup
-> Instructions to install dependencies and run frontend development environment.
+## Project Files 
+This is our basic file structure, including `build/`, `public/` and `src/`. 
+```
+/   
+├── build
+│   └── ...generated static resources: css, js, media
+│
+├── public
+│   └── ...favicon.ico, index.html, manifest.json
+│
+├── src
+│   └── ...development files
+│
+├── .gitignore
+├── package.json (dependencies, scripts, configuration)
+└── README.md
+```
+## Development
+For development, `src/` contains the main assets. There are `components/`, `resources/`, redux-based `actions/`, `constants/`, `reducers/` and `services/`.
 
-### Directory
-    .
-    ├── create-react-app        # For installing dependencies, you can delete after install
-    └── frontend                # Actual development environment
-         ├── other files...     # Stores App.js, components/, etc..
-         └── (to be updated)
+**Note**: each folder contains a file called `index.js`. This helps to shorten import statements, and the decision to include these is for convenience.
 
-### Install Create-React-App (only for dependencies)

-### Install Frontend
-Link: Current Page
+## Using this project
+The development server runs on `PORT 8000`.  See *scripts* in `package.json` to change.  
+Configure *apiUrl* at `src/index.js`. Default value: http://localhost:3000.  
 
-    cd ..
-    git clone https://github.com/IS3106-T07/frontend
-    cd frontend
-    npm install
+**Note**: `HTTPS` is required for service workers.  
+
+Run in **development**
+```
+npm install 
+npm start
+HTTPS=true npm start                    // Linux, macOS (bash)
+set HTTPS=true&&npm start               // Windows (cmd.exe)
+($env:HTTPS = $true) -and (npm start)   // Windows (powershell)
+```
+Run in **production**
+```
+npm install
+npm run build
+serve -s build
+```
+Run **tests**
+```
+npm build
+npm run test
+```
 
-### Testing
-    npm test
+## Creating a component
+```
+// todo Guide
+```
 
-### Run
-    npm start
-
-Running at http://localhost:3003 (and at specified IP network address, e.g. 192.168.1.40:3003)
-
-# FAQ
-> Frequently asked questions.
-
-### Q. I'm stuck at registry config, on install. How to proceed?
-Set config manually.
-
-    npm config set registry="http://registry.npmjs.org"
-
-### Q. Where is the PWA Setup Guide?
-See MANUAL.md.
