 # MERN Stack Template
 
+<img src='https://raw.githubusercontent.com/BenElferink/mern-template/refs/heads/images/images/mern.jpeg' />
+
 - **M** = [MongoDB](https://www.mongodb.com)
 - **E** = [Express.js](https://expressjs.com)
 - **R** = [React.js](https://reactjs.org)
 - **N** = [Node.js](https://nodejs.org)
 
-<br />
 <br />
 
-## How to use this template
+# What is this template?
+
+This template allows you to quick-start your Fullstack application using the MERN stack, it has a server setup with some basic authentication, and a client ready to communicate with the backend.
+
+<img src='https://raw.githubusercontent.com/BenElferink/mern-template/refs/heads/images/images/preview.png' />
 
 <br />
 
-### STEP 1:
+# How to use this template
 
-Click ["Use this template"](https://github.com/belferink1996/MERN-template/generate) to generate a new repository.<br />
-Then open your terminal and clone your repository:
+### 1. Generate repository from template:
 
-> cd ~/Desktop <br />
-> git clone https://github.com/[your-user-name]/[your-repo-name].git
+Click ["Use this template"](https://github.com/benelferink/mern-template/generate) to generate a
+new repo, then open your terminal and clone your new repo.
 
-<br />
+```
+git clone https://github.com/[your_user_name]/[your_repo_name].git
+```
 
-### STEP 2:
+### 2. Install dependencies:
 
-Go to your client folder (frontend), and set your workspace:
+Go to the `server` folder, and run `install`.
 
-> cd ~/Desktop/[your-repo-name]/client <br />
-> npm install <br />
-> npm start
+```
+cd ./server
+npm i
+```
 
-<br />
+Go to the `client` folder, and run `install`.
 
-### STEP 3:
+```
+cd ./client
+npm i
+```
 
-Prepare your MongoDB database,<br />
-then go to your server folder (backend), and set your workspace:
+### 3. Prepare MongoDB:
 
-> cd ~/Desktop/[your-repo-name]/server <br />
-> npm install <br />
+Prepare your MongoDB database (using [Atlas](https://www.mongodb.com/cloud/atlas),
+or [Community](<https://github.com/benelferink/mern-template/wiki/Install-MongoDB-Community-Server-(MacOS)>)). Then configure your database within `server/src/constants/index.js` (or `server/src/.env`), by configuring the `MONGO_URI` variable.
 
-Set your database within `index.js`, then start server:
+### 4. Start applications:
 
-> npm start
+Go to the `server` folder, and run `dev`.
 
-<br />
+```
+cd ./server
+npm run dev
+```
 
-### STEP 4: CODE !!!
+Go to the `client` folder, and run `dev`.
+
+```
+cd ./client
+npm run dev
+```
+
+### 5. Happy Coding !!!
