@ -38,42 +38,39 @@ commands will need to be adjusted for use in a Windows environment.
To simplify the command lines for this walkthrough, we need to define a few
environment variables.
1. Set a `PROJECT_ID` variable.
* If you don't have an existing GCP project that you'd like to use, replace
`my-knative-project` in the following command with the project ID you'd like to use. This variable
is used later to create your new GCP project. The project ID must be globally
unique across all GCP projects.
```bash
export PROJECT_ID=my-knative-project
```
Tip: Enter `gcloud config get-value project` to view the ID of your default GCP project.
1. Set `CLUSTER_NAME` and `CLUSTER_ZONE` variables:
```bash
export CLUSTER_NAME=knative
export CLUSTER_ZONE=us-west1-c
```
The CLUSTER_NAME needs to be lowercase and unique among any other Kubernetes
clusters in your GCP project. The zone can be
[any compute zone available on GCP](https://cloud.google.com/compute/docs/regions-zones/#available).
These variables are used later to create a Kubernetes cluster.

### Setting up a Google Cloud Platform project
You need a GCP project to create a Google Kubernetes Engine cluster.
1. Create a new GCP project and set it as your `gcloud` default, or set an
existing GCP as your `gcloud` default:
existing GCP project as your `gcloud` default:
* If you don't already have a GCP project created, create a new project in `gcloud`:
```bash
gcloud projects create $PROJECT_ID --set-as-default
gcloud projects create my-knative-project --set-as-default
```
Replace `my-knative-project` with the name you'd like to use for your GCP project.
You also need to [enable billing](https://cloud.google.com/billing/docs/how-to/manage-billing-account)
for your new project.
* If you already have a GCP project, make sure your project is set as your
`gcloud` default:
```bash
gcloud config set project $PROJECT_ID
gcloud config set project my-knative-project
```

1. Enable the necessary APIs:
```
gcloud services enable \
