+name: Develop in Linux on a Digital Ocean Droplet
+description: Get started with Linux development on a Digital Ocean Droplet.
+tags: [cloud, digitalocean]
+---
+
+# do-droplet-linux
+
+This is an example for deploying workspaces on Digital Ocean Droplets.
+
+## Requirements
+
+- Digital Ocean Personal Access Token (PAT)
+- Digital Ocean Project ID (e.g. `doctl projects list`)
+  - Remove `variable "step2_do_project_id"` and `resource "digitalocean_project_resources" "project"` if you don't want project association.
