# Union

`@anymux/union` lets you overlay multiple `IFileSystem` instances into one unified view. Files are resolved from the highest-priority layer first, with writes going to the designated writable layer.

## Features

* Combine multiple file systems into a single namespace
* Priority-based file resolution
* Configurable writable layer
