+# Build OpenROAD on Windows Using Docker
+
+## Prerequisites
+
+* Windows 10 (version 2004+) or Windows 11
+* Docker Desktop (WSL2 backend enabled)
+* At least 16GB RAM (8GB minimum usable)
+* At least 50GB free disk space
+* VS Code (optional, recommended)
+
+## Step 1 — Install and Configure Docker Desktop
+
+> Run in PowerShell (Administrator)
+
+1. Install Docker Desktop with WSL2:
+   [https://docs.docker.com/desktop/windows/wsl/](https://docs.docker.com/desktop/windows/wsl/)
+
+2. Configure resources:
+   * Memory: ≥ 8GB
+   * CPUs: ≥ 4
+
+3. Enable WSL Integration:
+   Docker Desktop → Settings → Resources → WSL Integration → Enable Ubuntu-22.04
+
+Verify installation:
+
+bash
+docker run --rm hello-world
+
+## Step 2 — Avoid Timezone Prompt
+
+> Run inside Docker container
+
+bash
+export DEBIAN_FRONTEND=noninteractive
+export TZ=UTC
+apt-get update
+apt-get install -y tzdata
+
+## Step 3 — Install Correct Yosys Version
+
+> Run inside Docker container
+
+bash
+wget https://github.com/YosysHQ/oss-cad-suite-build/releases/download/2025-03-01/oss-cad-suite-linux-x64.tgz
+tar -xzf oss-cad-suite-linux-x64.tgz
+echo 'export PATH="$(pwd)/oss-cad-suite/bin:$PATH"' >> ~/.bashrc
+source ~/.bashrc
+yosys --version
+
+## Step 4 — Fix Line Endings (CRLF Issue)
+
+> Run in PowerShell
+
+bash
+git config --global core.autocrlf false
+git config --global core.eol lf
+git clone --recursive https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts
+
+## Step 5 — Copy Files into Docker
+
+### Option A: Copy files
+
+> Run in PowerShell
+
+bash
+docker ps
+docker cp C:\path\to\file <container_id>:/tmp/
+
+### Option B (Recommended): Mount volume
+
+> Run in PowerShell
+
+bash
+docker run -it -v //c/Users/YourName/OpenROAD-flow-scripts:/OpenROAD-flow-scripts ubuntu:22.04
+
+## Step 6 — Persist Environment
+
+> Run inside Docker container
+
+bash
+echo 'export PATH="$(pwd)/oss-cad-suite/bin:$PATH"' >> ~/.bashrc
+source ~/.bashrc
+docker commit <container_id> openroad-windows:latest
+docker run -it openroad-windows:latest
+
+## Step 7 — Run Example Design
+
+> Run inside Docker container
+
+bash
+cd /OpenROAD-flow-scripts/flow
+make DESIGN_CONFIG=./designs/nangate45/gcd/config.mk
+
+## Step 8 — VS Code Integration
+
+### Beginner: Attach to Running Container
+
+1. Install VS Code: [https://code.visualstudio.com/](https://code.visualstudio.com/)
+2. Install Dev Containers extension
+3. Run container:
+
+bash
+docker run -it -v //c/Users/YourName/OpenROAD-flow-scripts:/OpenROAD-flow-scripts openroad-windows:latest
+
+4. In VS Code press `Ctrl+Shift+P` → Select "Attach to Running Container" → Choose your container
+
+### Intermediate: Open Folder in Container
+
+Press `Ctrl+Shift+P` → "Dev Containers: Open Folder in Container" → Choose your project folder
+
+### Advanced: DevContainer Setup
+
+Create `.devcontainer/devcontainer.json`:
+
+json
+{
+  "name": "OpenROAD Development",
+  "image": "openroad/orfs:latest",
+  "workspaceMount": "source=${localWorkspaceFolder},target=/OpenROAD-flow-scripts,type=bind",
+  "workspaceFolder": "/OpenROAD-flow-scripts",
+  "customizations": {
+    "vscode": {
+      "extensions": [
+        "ms-vscode.cpptools-extension-pack",
+        "twxs.cmake"
+      ]
+    }
+  },
+  "remoteUser": "root"
+}
+
+Press `Ctrl+Shift+P` → "Dev Containers: Reopen in Container"
+
+## Common Issues
+
+### Yosys too old
+
+Use OSS CAD Suite (Step 3)
+
+### apt-get stuck
+
+bash
+export DEBIAN_FRONTEND=noninteractive
+
+### GUI not working
+
+bash
+docker run -it -e DISPLAY=<YOUR_IP>:0.0 openroad/orfs
+
+### Slow performance
+
+Use WSL path: `\\wsl$\Ubuntu\`
+
+### Disk space fix
+
+bash
+wsl --export Ubuntu-22.04 D:\ubuntu_backup.tar
+wsl --import Ubuntu-22.04 D:\WSL\Ubuntu D:\ubuntu_backup.tar
+
+### VS Code not connecting
+
+* Ensure Docker Desktop is running
+* Restart VS Code
+* Check Dev Containers extension is installed
+
+## Optional: WSL2 Native Build
