re-focusing the "Getting Started" doc

My primary goal here is to make this doc as short as possible while
still getting the user their first win using defang.

 # Getting Started
 
 
-### Install the CLI
+## Install the CLI
 
 First, you'll need to install the Defang CLI. The CLI is the primary way to interact with Defang. It allows you to create, deploy, and manage your services. You can find the [different installation methods here](./installing.md).
 
-### Authenticate with Defang
+## Generate a project
 
-To do pretty much anything with Defang, you'll need to authenticate with the platform. You can do this by running the following command:
+```
+$ defang generate nodejs-http
+```
 
-```bash
-defang login
+You should see the following prompt:
 ```
+? What folder would you like to create the project in?
+```
+Type in the name of the folder you'd like to use for your new project and press ENTER.
 
-:::info
-To learn more about how authentication works in defang, check out the [authenticating page](./authenticating.md).
-:::
+I'll type `"welcome-to-defang"`. Now, you'll see the following output:
 
-### Agree to the terms of service
+```
+? What folder would you like to create the project in? welcome-to-defang
+ * Fetching sample from the Defang repository...
+ * Writing files to disk...
+   - .github/
+   - .github/workflows/
+   - .github/workflows/deploy.yaml
+   - README.md
+   - app/
+   - app/Dockerfile
+   - app/main.js
+   - compose.yaml
+ * Code generated successfully in folder welcome-to-defang
+
+Check the files in your favorite editor.
+To deploy the service, do `cd welcome-to-defang` and
+
+  defang compose up
+```
 
-Before you can deploy code you should read and agree to our the terms of service. You can do this by running:
+Now, navigate to the folder you just created:
 
-```bash
-defang terms
+```
+$ cd welcome-to-defang
 ```
 
-### Build and Deploy Services
+You can open the folder in your favorite editor and see the files that were generated for you:
+* The `app` folder contains the code for your service.
+* The `Dockerfile` is used to build the container image for your service.
+* The `compose.yaml` file is used to define the services you want to deploy.
 
-Defang supports various ways of creating and deploying services to the cloud. The following tutorials dive into each one in more detail:
+## Deploy to the playground
 
-1. [Deploy an outline using AI](../tutorials/generate-new-code-using-ai.mdx)
-2. [Build and deploy your code](../tutorials/deploy-code-compose.mdx)
-3. [Deploy existing containers](../tutorials/deploy-container-using-the-cli.mdx)
-4. [Deploy using Pulumi](../tutorials/deploy-using-pulumi.mdx)
+Go back to your shell and type the following:
 
+```
+$ defang up
+```
 
-### Monitor Services
+If you have not used defang before, you'll be prompted to log in.
 
-By default, all the output (stdout and stderr) from your app is logged. You can view these logs in real-time. You can view logs for all your services, one service, or even one specific deployment of a service.

+## Next Steps
 
+Congratulations! You've successfully deployed your first service with Defang. Now, where do you go from here?
 
-### Update Services
+Defang supports various ways of creating and deploying services to the cloud. The following tutorials dive into each one in more detail:
 
-To update your app (for example, updating the base image of your container, or making changes to your code) you can run the `defang compose up` command and it will build and deploy a new version with zero downtime. Your current version of the service will keep running and handling traffic while the new version is being built and deployed. Only after the new version passes the health checks and accepts traffic will the older version be stopped.
+1. [Update the code and redeploy](/docs/getting-started/build-and-deploy)
+2. [Monitor your services](/docs/getting-started/monitor)
+3. [Deploy an outline using AI](/docs/tutorials/generate-new-code-using-ai)
+4. [Build and deploy your code](/docs/tutorials/deploy-code-compose)
+5. [Deploy existing containers](/docs/tutorials/deploy-container-using-the-cli)
+6. [Deploy using Pulumi](/docs/tutorials/deploy-using-pulumi)
 
-:::info
-If you are using [compose files](../concepts/compose.md) to define your services, you can add/remove services, make changes to code, etc. When you run `defang compose up`, the update will be diffed against the current state and any necessary changes will be applied to make the current state match the desired state.
