Create the file `plans/todoapp.cue` with the following content:
```cue file=./tests/getting-started/plans/todoapp.cue
```
This file will define the resources and relationships between them that are common across _all environments_. For example, here we are deploying to our local Docker engine in our `local` environment, but for staging or production as examples, we would deploy the same image to some other container orchestration system such as Kubernetes hosted somewhere out there among the various cloud providers.

You should see the following output:
```bash

app.source dagger.#Artifact false Application source code
run.socket struct false Mount local docker socket

app.source dagger.#Artifact false Application source code
dockerSocket struct false Mount local docker socket

Let’s provide them now:
```shell
dagger -e local input socket run.socket /var/run/docker.sock
dagger -e local input socket dockerSocket /var/run/docker.sock
dagger -e local input dir app.source ./
```
This defines the `run.socket` as a `socket` input type, and the `app.source` input as a `dir` input type.
This defines the `dockerSocket` as a `socket` input type, and the `app.source` input as a `dir` input type.
Now let’s replay the `dagger input list` command:
```bash
Input Value Set by user Description
app.source dagger.#Artifact true Application source code
run.socket struct true Mount local docker socket
Input Value Set by user Description
app.source dagger.#Artifact true Application source code
dockerSocket struct true Mount local docker socket
```
Notice that Dagger now reports that both inputs have been set.

This guide will use the same directory as the root of the Dagger project and the Cue module, but you can create your Cue module anywhere inside the Dagger project. In general, you won't have to worry about it at all. You will initialize a dagger project with the following command.
```shell
dagger init # Optional, already present in `todoapp`
dagger init
```
> In our case, `todoapp` already contains a `.dagger` directory, so this step is optional.
