+## File Extensions
+While UNIX systems do not demand for file extensions, Windows do have its
+complex and heavy requirement for it. As a practice, the file extension shall
+always be lead by the UNIX (`.sh*`) and ends with Windows (either `*.cmd` for
+Batch initialization or `*.ps1` for PowerShell initialization).
 
+For the highest portability, I recommend keeping the initialization with Batch
+mode since its execution can auto-correct to PowerShell mode when available
+(Refer [posix-powershell.sh.ps1](posix-powershell.sh.ps1) for how it's done).
