# Creating an app with Codex CLI

To get started with Codex CLI for Uno Platform development:

1. Create a new project using the [Uno Platform Live Wizard](https://aka.platform.uno/app-wizard), or [`dotnet new`](xref:Uno.GetStarted.dotnet-new)

    ```bash
    dotnet new unoapp --tfm net10.0 -o MyNewApp
    ```

1. Change your directory to be in the folder containing the new project (e.g., `cd MyNewApp`)
1. Run the following command, which will launch the Uno Studio app that will allow you to [sign in or create an account](xref:Uno.GetStarted.Licensing) and get access to the [Uno App MCP](xref:Uno.Features.Uno.MCPs).

    ```bash
    dotnet dnx -y uno.devserver login
    ```

1. If running on linux or macos, run the following:

    ```bash
    export NUGET_PACKAGES=`pwd`/.nuget
    ```

1. Open Codex in the folder of the app

    ```bash
    codex --sandbox workspace-write --ask-for-approval on-request 
    ```

## Next Steps

You can start developing with [**Codex**](xref:Uno.BuildYourApp.AI.Agents).
