+### Scopes
+
+Just like variables, functions belong to a specific scope. When you create a
+function, it is available only in the scope in which it was created. To make a
+function available, use a scope modifier when you create the function. For more
+information, see [about_Scopes][15].
+
+The following example uses the `global:` scope modifier to create a function in
+the global scope.
+
+```powershell
+function New-Function {
+    param(
+        [string] $Name,
+        [scriptblock] $Script
+    )
+
+    $lp = "Function:\global:$($name)"
+    Set-Item -LiteralPath $lp -Value $script -PassThru -Force
+}
+
+New-Function -Name 'Win32:' -Script { Set-Location C:\Windows\System32 }
+```
+
+Without the `global:` scope modifier, the function would be created in the
+local scope. When `New-Function` exits the newly created function would no
+longer exist.
