 # Get Started with Dagger
 
-In this tutorial, you will learn the basics of Dagger by building a Dagger project from scratch. This simple project deploys a [React](https://reactjs.org/) application to your local machine via Docker. In later tutorials, you will learn how to configure Dagger to deploy to your infrastructure. And, for advanced users, how to share access to your infrastructure in the same way that we share access to ours now.

 A Dagger _plan_ is written in CUE and defines the _resources_, _dependencies_, and _logic_ to deploy an application to an environment. Unlike traditional glue code written in a scripting language such as Bash or PowerShell, a Dagger plan is _declarative_ rather than _imperative_. This frees us from thinking about the order of operations, since Dagger will infer dependendencies and calculate correct order on its own.

 ### Define Input Values per Environment
 
-Our Dagger plan includes a number of references to `dagger.#Input` which inform the Dagger engine that the concrete value should be pulled from inputs. While some things such as the registry target we saw above can be expressed purely in CUE, others such as directories, secrets, and sockets are required to be explicitly defined as _inputs_ to protect against malicious code  being injected by third-party packages. If Dagger allowed such things to be stated in CUE, the entire package system could become a source of attacks.
