+## Use private mirror
+
+It is possible to use a private mirror hosting Node.js binaries. This mirror must be a full mirror of the official Node.js distribution.
+The mirror URL can be set using the `mirror` input.
+It is possible to specify a token to authenticate with the mirror using the `mirror-token` input.
+The token will be passed as a bearer token in the `Authorization` header.

+    mirror: 'https://nodejs.org/dist'
+    mirror-token: 'your-mirror-token'
