+        .SYNOPSIS
+        Mask a value in GitHub Actions
+
+        .DESCRIPTION
+        Masking a value prevents a string or variable from being printed in the log. Each masked word separated by whitespace is
+        replaced with the * character. You can use an environment variable or string for the mask's value. When you mask a value,
+        it is treated as a secret and will be redacted on the runner. For example, after you mask a value, you won't be able to
+        set that value as an output.
+
+        .EXAMPLE
+        Add-Mask $SecretValue
+
+        Masks the value of $SecretValue so that its printed like ***.
+
+        .EXAMPLE
+        $SecretValue1, $SecretValue2 | Mask
+
+        Masks the value of $SecretValue1 and $SecretValue2 so that its printed like ***, using the pipeline
