 # Google Compute Builder
 
 Type: `googlecompute`
 
-The `googlecompute` Packer builder is able to create [images](https://developers.google.com/compute/docs/images) for use with
-[Google Compute Engine](https://cloud.google.com/products/compute-engine)(GCE) based on existing images. Google

 ## Authentication
 
-Authenticating with Google Cloud services requires at most one JSON file,
-called the _account file_. The _account file_ is **not** required if you are running
-the `googlecompute` Packer builder from a GCE instance with a properly-configured
-[Compute Engine Service Account](https://cloud.google.com/compute/docs/authentication).

 ### Running With a Compute Engine Service Account
-If you run the `googlecompute` Packer builder from a GCE instance, you can configure that
-instance to use a [Compute Engine Service Account](https://cloud.google.com/compute/docs/authentication). This will allow Packer to authenticate
-to Google Cloud without having to bake in a separate credential/authentication file.
 
-To create a GCE instance that uses a service account, provide the required scopes when
-launching the instance.

-Centos images have root ssh access disabled by default. Set `ssh_username` to any user, which will be created by packer with sudo access.

-The machine type must have a scratch disk, which means you can't use an `f1-micro` or `g1-small` to build images.
