+# package-method-winget
+
+## Usage
+This module enables a `winget` package method used with policy like:
+
+```cf3
+packages:
+  windows::
+    "Microsoft.WindowsTerminal"
+      package_method => winget,
+      package_policy => "add";
+```
+
+## Opt-in for accepting source and package agreements (Required)
+
+In order for winget to operate properly you must opt-in to accepting source and packaging agreements.
+Without this acceptance the package method will fail with a message like:
+
+```console
+    info: Installing Microsoft.WindowsTerminal...
+    info: Q:powershell.exe -Comm ...:You must set some vars for package-method-winget to work
+   error: Finished command related to promiser 'Microsoft.WindowsTerminal' -- an error occurred, returned 1
+   error: Bulk package schedule execution failed somewhere - unknown outcome for 'Microsoft.WindowsTerminal'
+```
+
+Acceptance can be given either via cfbs inputs, augments, group or host specific data.
+
+Set the value of `yes` in the following variables:
+- `data:package_method_winget.accept_source_agreements`
+- `data:package_method_winget.accept_package_agreements`
+
+## Installation
+This module uses both the `winget` command as well as the `Microsoft.WinGet.Client` PowerShell module as that makes it easier to gather software inventory of currently installed packages.
+
+`winget` should be installed on most newer desktop systems by default.
+Server images often do not have `winget` installed.
+
+In order for `winget` and `Microsoft.WinGet.Client` to be installed, ps1 scripts must be run which requires `PowerShell Execution policy` `Unrestricted` for `LocalMachine`.
+The policy by default will not make this change.
+You must opt-in by setting the variable `winget_installed.allow_powershell_execution_policy_change` to the value of `yes`.
+This can be set in Host/Group data or via Augments in the `data` namespace.
+
+```json
+{
+  "variables": {
+    "data:winget_installed.allow_powershell_execution_policy_change": {
+      "value": "yes"
+    }
+  }
+}
+```
