62−IMPORTANT FOR WINDOWS USERS:
63−- This tool uses a POSIX shell emulator (mvdan.cc/sh/v3) that works cross-platform, including Windows
64−- On Windows, this provides bash-like functionality without requiring WSL or Git Bash
65−- Use forward slashes (/) in paths - they work on all platforms and are converted automatically
66−- Windows-specific commands (like 'dir', 'type', 'copy') are not available - use Unix equivalents ('ls', 'cat', 'cp')
67−- Environment variables use Unix syntax: $VAR instead of %%VAR%%
68−- File paths are automatically converted between Windows and Unix formats as needed
85+CROSS-PLATFORM SHELL SUPPORT:
86+- Unix/Linux/macOS: Uses native bash/sh shell
87+- Windows: Intelligent shell selection:
88+ * Windows commands (dir, type, copy, etc.) use cmd.exe
89+ * PowerShell commands (Get-, Set-, etc.) use PowerShell
90+ * Unix-style commands (ls, cat, etc.) use POSIX emulation
91+- WSL: Automatically treated as Linux (which is correct)
92+- Automatic detection: Chooses the best shell based on command and platform
93+- Persistent state: Working directory and environment variables persist between commands
94+
95+WINDOWS-SPECIFIC FEATURES:
96+- Native Windows commands: dir, type, copy, move, del, md, rd, cls, where, tasklist, etc.
97+- PowerShell support: Get-Process, Set-Location, and other PowerShell cmdlets
98+- Windows path handling: Supports both forward slashes (/) and backslashes (\)
99+- Drive letters: Properly handles C:\, D:\, etc.
100+- Environment variables: Supports both Unix ($VAR) and Windows (%%VAR%%) syntax
