 ## :zap: Quick Setup
 
+### :page_with_curl: Prerequisites
+
+1. You need to have `node` v16+ and `npm` v8+ installed on your machine. If you don't have it yet, you can install it by running the following command.
+
+   1. For Mac
+
+      ```bash
+      brew install node
+      ```
+
+   2. For Windows
+
+      ```bash
+      choco install nodejs
+      ```
+
+   3. For Linux
+
+      ```bash
+      sudo apt install nodejs
+      ```
+
+   4. Using [Node Version Manager](https://github.com/nvm-sh/nvm) (Recommended)
+
+      ```bash
