 This guide explains how to use Rstack CLI in a monorepo, including how it works with task orchestrators such as [Turborepo](https://turborepo.com/docs) and [Nx](https://nx.dev/docs/getting-started/intro).
 
-It covers managing Rstack dependencies, configuring lint and staged-file tasks at the root, and defining separate configurations for web applications and libraries.
