+.SYNOPSIS
+        Writes a changelog from Git commits
+.DESCRIPTION
+        This PowerShell script writes an automated changelog in Markdown format to the console by using the Git commits only.
+	NOTE: For proper sorting the Git commits should start with verbs such as 'Add', 'Fix', 'Update', etc. You may also redirect the output into a file for later use.
+.PARAMETER RepoDir
+	Specifies the path to the local Git repository (default is current working dir)
+.EXAMPLE
+        PS> ./write-changelog.ps1
+	  
+	Changelog of PowerShell
+	=======================
