# Remote Development on Hetzner Cloud (Linux)
11+
12+
Provision Hetzner Cloud servers as [Coder workspaces](https://coder.com/docs/workspaces) with this example template.
13+
14+
## Prerequisites
15+
16+
To deploy workspaces as Hetzner Cloud servers, you'll need:
17+
18+
- Hetzner Cloud [API token](https://console.hetzner.cloud/projects) (create under Security > API Tokens)
19+
20+
### Authentication
21+
22+
This template assumes that the Coder Provisioner is run in an environment that is authenticated with Hetzner Cloud.
23+
24+
Obtain a Hetzner Cloud API token from your [Hetzner Cloud Console](https://console.hetzner.cloud/projects) and provide it as the `hcloud_token` variable when creating a workspace.
25+
For more authentication options, see the [Terraform provider documentation](https://registry.terraform.io/providers/hetznercloud/hcloud/latest/docs#authentication).
26+
27+
> **Note**
28+
> This template is designed to be a starting point! Edit the Terraform to extend the template to support your use case.
