Getting Started

Step 1: environment and your first node

• Pin the version and platform first
  Each ROS 2 distribution is tied to specific Ubuntu versions. Before choosing, check which Ubuntu release your target distribution supports and whether upstream still maintains it (follow the official release cadence and EOL announcements). Version facts come from official documentation only.
• Get turtlesim and talker/listener running
  Do not skip the official beginner tutorials: they verify DDS discovery, environment variables and workspace configuration.
• Build a minimal workspace of your own
  One package, one node, one launch file — repeatable builds before features.
