  * We will, at times update the version of V8 shipped in the release line
  * if it can be made ABI compatible with the previous version.
  *
+ * Embedders building Node.js can define NODE_EMBEDDER_MODULE_VERSION to
+ * override the default value of NODE_MODULE_VERSION.
+ *
  * The registry of used NODE_MODULE_VERSION numbers is located at
  *   https://github.com/nodejs/node/blob/HEAD/doc/abi_version_registry.json
  * Extenders, embedders and other consumers of Node.js that require ABI
  * version matching should open a pull request to reserve a number in this
  * registry.
