-# Windows Compatibility Guide
-
-This document outlines Windows compatibility issues and solutions for the envr project.
-
-## Critical Issues
-
-### 1. Path Handling Bug (MUST FIX)
-
-**File:** `app/env_file.go:209`
-
-**Issue:** Uses `path.Join` instead of `filepath.Join`, which won't work correctly on Windows due to different path separators.
-
-**Current code:**
-```go
-f.Path = path.Join(newDir, path.Base(f.Path))
-```
-
-**Fixed code:**
-```go
-f.Path = filepath.Join(newDir, filepath.Base(f.Path))
-```
-
-## External Dependencies
-
-The application relies on external tools that need to be installed separately on Windows:
-
-### Required Tools
-
-1. **fd** - Fast file finder
-   - Install via: `winget install sharkdp.fd` or `choco install fd`
-   - Alternative: `scoop install fd`
-
-## Minor Compatibility Notes
-
-### File Permissions
-- Unix file permissions (`0755`, `0644`) are used throughout the codebase
-- These are safely ignored on Windows - no changes needed
-
-### Editor Configuration
-**File:** `cmd/edit_config.go:20-24`
-
-**Issue:** Relies on `$EDITOR` environment variable which is less common on Windows.
-
-**Current behavior:** Fails if `$EDITOR` is not set
-
-**Recommended improvement:** Add fallback detection for Windows editors:
-```go
-editor := os.Getenv("EDITOR")
-if editor == "" {
-    if runtime.GOOS == "windows" {
-        editor = "notepad.exe"  // or "code.exe" for VS Code
-    } else {
-        fmt.Println("Error: $EDITOR environment variable is not set")
-        return
-    }
-}
-```
-
-## Installation Instructions for Windows
-
-1. Install required dependencies:
-   ```powershell
-   winget install sharkdp.fd
-   ```
-
-2. Fix the path handling bug in `app/env_file.go:209`
-
-3. Build and run as normal:
-   ```powershell
-   go build
-   .\envr.exe init
-   ```
-
-## Testing on Windows
-
-After applying the critical path fix, the core functionality should work correctly on Windows. The application has been designed with cross-platform compatibility in mind, using:
-
-- `filepath` package for path operations (mostly)
-- `os.UserHomeDir()` for home directory detection
-- Standard Go file operations
-
-## Summary
-
-- **1 critical bug** must be fixed for Windows compatibility
-- **2 external tools** need to be installed
-- **1 minor enhancement** recommended for better Windows UX
-- Overall architecture is Windows-compatible
