+This guide introduces setting up a server with Docker and organizing sections to help users get started with development environments.

+* '''From Source on a Computer''': Direct installation on a local system.
+* '''Within a Dockerfile''': Create a base Dockerfile for repeatable setups.
+* '''Remotely with Ansible''': Automate Docker setup across multiple servers.
