+# Ruby Development Environment with Docker
+---
+
+# **Ruby Development with Docker (Linux & Windows Containers)**  
+
+## **Overview**  
+This project provides **Docker containers** for Ruby development on both **Linux** and **Windows** environments.  
+
+- 🐧 **Linux Container**: Uses the official [`ruby:3.1.2`](https://hub.docker.com/_/ruby) Docker image for a lightweight setup.  
+- 🖥️ **Windows Container**: Based on **Windows Server Core LTSC 2022**, installing Ruby via **Chocolatey**.  
+
+---
+
+## **System Requirements**  
+### **For Linux/macOS users (WSL2 or native Linux/macOS)**  
+✅ Docker Desktop with **Linux containers enabled**  
+✅ macOS/Linux terminal (or WSL2 for Windows users)  
+
+### **For Windows users**  
+✅ Docker Desktop with **Windows containers enabled**  
+✅ Windows 10/11 (Pro, Enterprise, or Education)  
+
+---
+
+## **How to Build the Containers**  
+
+### **Building the Linux Container**  
+```sh
+docker build -t ruby-linux -f Dockerfile.linux .
+```
+
+### **Building the Windows Container**  
+```powershell
+docker build -t ruby-windows -f Dockerfile.windows .
+```
+
+To specify a **different Ruby version**, use `--build-arg`:
+```sh
+docker build --build-arg rubyVersion=3.2.0 -t ruby-linux -f Dockerfile.linux .
+```
+```powershell
+docker build --build-arg rubyVersion=3.2.0 -t ruby-windows -f Dockerfile.windows .
+```
+
+---
+
+## **How to Run the Containers**  
+
+### **Running the Linux Container**
+```sh
+docker run -it --rm -v $(pwd):/workspace ruby-linux bash
+```
+- Mounts the current project directory to `/workspace` inside the container.  
+- Starts an interactive shell session.  
+
+### **Running the Windows Container**
+```powershell
+docker run -it --rm -v ${PWD}:/workspace ruby-windows powershell
+```
+- Mounts the project directory as `C:\workspace`.  
+- Starts an interactive PowerShell session.  
+
+---
+
+## **Switching Between Windows and Linux Containers**  
+⚠ **IMPORTANT:** Docker **cannot run both Linux and Windows containers simultaneously**. If you're switching between them:  
+
+### **Switch to Linux Containers**  
+1. Open **Docker Desktop**.  
+2. Click the **Settings** ⚙️ icon.  
+3. Under **General**, check **"Use the WSL 2 based engine"**.  
+4. Right-click the Docker icon in the system tray → **Switch to Linux containers**.  
+
+### **Switch to Windows Containers**  
+1. Right-click the **Docker Desktop** icon in the system tray.  
+2. Select **"Switch to Windows containers"**.  
+
+---
+
+## **Verifying Ruby Installation**
+Once inside a running container, check the installed Ruby version:  
+```sh
+ruby -v
+```
+
+---
+
+## **Troubleshooting**
+❌ **Issue:** "Cannot switch to Windows/Linux containers"  
+✅ **Solution:** Restart **Docker Desktop** and try again.  
+
+❌ **Issue:** "Mounting volume fails on Windows"  
+✅ **Solution:** Ensure **file sharing** is enabled in Docker settings under **Resources > File Sharing**.  
+
+❌ **Issue:** "Exception calling "DownloadString" with "1" argument(s): "The remote name could not be resolved: 'community.chocolatey.org'"  
+✅ **Solution:** Ensure **Docker network ls** is using the correct network.
+ - docker network ls
+ - docker network inspect "name"
+ - use the right network: docker build --network="NameOfNetwork" -t ruby-windows -f
