 ## [0.3.0](https://github.com/sbrow/envr/compare/v0.2.1...v0.3.0) (2026-06-16)
 
-Version 0.3.0 represents a significant departure (and improvement) for envr.
-The entire codebase was rewritten in [Odin](https://odin-lang.org/) (from Go).
-This reduced the binary size from over 17MB to under 600k, improved performance,
-and significantly reduced the number of project dependencies from 69 to just 2.

+# 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`
+
+2. **git** - Version control system
+   - Install via: `winget install Git.Git` or download from git-scm.com
+   - Usually already available on most development machines
+
+## 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
+   winget install Git.Git
+   ```
+
+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
