+# Remote Development on Linode Instances
+
+Provision Linode instances as [Coder workspaces](https://coder.com/docs/workspaces) with this example template.
+
+<!-- TODO: Add screenshot -->
+
+## Prerequisites
+
+To deploy workspaces as Linode instances, you'll need:
+
+- Linode [personal access token (PAT)](https://www.linode.com/docs/products/tools/api/guides/manage-api-tokens/)
+
+### Authentication
+
+This template assumes that the Coder Provisioner is run in an environment that is authenticated with Linode.
+
+Obtain a [Linode Personal Access Token](https://cloud.linode.com/profile/tokens) and set the `LINODE_TOKEN` environment variable to the access token.
+For other ways to authenticate [consult the Terraform provider's docs](https://registry.terraform.io/providers/linode/linode/latest/docs).
+
+## Architecture
+
+This template provisions the following resources:
+
+- Linode instance (ephemeral, deleted on stop)
+- Linode volume (persistent, mounted to `/home/coder`)
+
+This means, when the workspace restarts, any tools or files outside of the home directory are not persisted. To pre-bake tools into the workspace (e.g. `python3`), modify the VM image, or use a [startup script](https://registry.terraform.io/providers/coder/coder/latest/docs/resources/script).
+
+> [!NOTE]
+> This template is designed to be a starting point! Edit the Terraform to extend the template to support your use case.
