+### Windows Installation
+
+Download the latest Windows binary from [GitHub Releases](https://github.com/satococoa/wtp/releases):
+
+**PowerShell:**
+```powershell
+# Download the zip file
+Invoke-WebRequest -Uri "https://github.com/satococoa/wtp/releases/latest/download/wtp_Windows_x86_64.zip" -OutFile "wtp.zip"

+
+# Add to PATH (add this line to your PowerShell profile for persistence)
+$env:PATH += ";$env:LOCALAPPDATA\wtp"
+```
+
+**Git Bash:**
+```bash
+# Download and extract
+curl -L https://github.com/satococoa/wtp/releases/latest/download/wtp_Windows_x86_64.zip -o wtp.zip
+unzip wtp.zip -d ~/bin

 > `source /opt/homebrew/etc/profile.d/bash_completion.sh` (or the path shown

 After reloading your shell you get the same experience as Homebrew users.
 
+#### Windows Setup
+
+**PowerShell:**
+
+Add to your PowerShell profile (`$PROFILE` - typically `~\Documents\PowerShell\Microsoft.PowerShell_profile.ps1` or `~\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1`):
+
+```powershell
+# Add wtp shell integration (completion + cd functionality)
+$WarningPreference = 'SilentlyContinue'
+Invoke-Expression -Command (& wtp shell-init pwsh | Out-String)
+$WarningPreference = 'Continue'
+```
+
+To find your profile location, run `echo $PROFILE` in PowerShell. If the file doesn't exist, create it first:
+```powershell
+New-Item -Path $PROFILE -Type File -Force
+```
+
+**Git Bash:**
+
+Add to `~/.bashrc`:
+
+```bash
+# Add wtp shell integration (completion + cd functionality)
+eval "$(wtp shell-init bash)"
+```
+
+Git Bash on Windows uses the same Bash configuration as Linux, so the standard Bash setup works as-is.
