+# This is the Garden installer for Windows. Here's a brief description of what
+# it does:
+#
+# 1. Checks whether Hyper-V is enabled.
+# 2. Checks whether Docker is installed.
+# 3. Checks whether Kubernetes is the default orchestrator for Docker.
+# 4. Installs Stern.
+# 5. Installs the Chocolatey package manager.
+# 6. Installs the listed dependencies using Chocolatey if they're not already 
+#    present (currently git, nodejs, rsync, and kubernetes-helm).
+# 7. Installs the windows-build-tools NPM package.
+# 8. Install the garden-cli NPM package.
+#
+# To execute it run the following command in PowerShell:
+# Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object System.Net.WebClient).DownloadString('https://garden.io/Windows.ps1'))
+#
