+# **Local Development Environment Setup**
+
+### **Installing Golang**
+1. **Download Golang**  
+   Visit the official [Golang Downloads Page](https://golang.org/dl/) and select the installer appropriate for your operating system:
+   - **Windows**: `.msi` installer  
+   - **macOS**: `.pkg` installer  
+   - **Linux**: `.tar.gz` archive  
+
+2. **Install Golang**
+   - **Windows/macOS**:  
+     Run the installer and follow the on-screen instructions. This will automatically configure Golang and set environment variables.  
+   - **Linux**:  
+     Extract the archive and move the files to `/usr/local`:  
+     ```bash
+     sudo tar -C /usr/local -xzf go<version>.linux-amd64.tar.gz
+     ```  
+     Add Golang to your `PATH` by appending this line to your shell's configuration file (`~/.bashrc`, `~/.zshrc`, etc.):  
+     ```bash
+     export PATH=$PATH:/usr/local/go/bin
+     ```  
+     Save the changes and reload your shell:  
+     ```bash
+     source ~/.bashrc
+     ```
+
+3. **Verify Installation**  
+   Open a terminal and run:  
+   ```bash
+   go version
+   ```  
+   If Golang is installed correctly, the installed version will be displayed.
