+# README.md
+
+This GitHub repository contains files referenced by Wilson Mar's
+Git and GitHub course.
+
+File names ending in <strong>.ps1</strong> are PowerShell scripts that run on Windows,
+but now also Mac and Linux machines after installing Microsoft's PowerShell.
+
+File names ending in <strong>.sh</strong> are Bash scripts that normally run on Mac,
+and now also on Anniversary Edition Windows 10 machines.
+Such scripts are being phased out in favor of a PowerShell script for use by all.
+
+Learners make use of two sets of scripts that issue <strong>git commands</strong>
+so you can experiment to see what happens when you make a change to commands.
+
+<strong>git-sisters-update.ps1</strong> is a PowerShell script that
+clones a sample sample repository you forked on GitHub.
+It calls a script that sets git configurations for a project (or globally)<br />
+<strong>git_client-config.ps1</strong>
+
+<strong>git-sample-repo-create.ps1</strong> is a PowerShell script that
+creates a repository on your local clones your fork of a sample sample repository.
+
+All these scripts create a folder, but that folder is deleted at the beginning of each run.
+
+Enjoy!
