Use this skill for full walkthroughs and larger example applications.

## Core tutorial workflow

- Load only the tutorial and part needed for the current step. Unity and Unreal parts are long and depend on prior state.
- Preserve part ordering: setup, server module, bindings/connection, gameplay/client behavior, deployment.
- Keep the tutorial's database name, module path, generated binding path, and package/tooling choices consistent unless the user asks to adapt them.
- When adapting a tutorial into an existing app, map tutorial concepts to local project names before copying code.
- Route narrow API questions to the matching focused skill rather than loading a full tutorial part.

## Tutorial map

- Chat app: full server and client walkthrough with tables, reducers, publish, SQL, and generated clients.
- Unity Blackhol.io: Part 1 setup, Part 2 server and connection, Part 3 spawning/login/arena/client objects, Part 4 movement/collisions/Maincloud.
- Unreal Blackhol.io: Part 1 setup, Part 2 server and connection, Part 3 spawning/Blueprints/player controller, Part 4 movement/collisions/Maincloud.

| Unreal tutorial | `references/tutorials-unreal*.md`                                    |

## Guidance

- Keep tutorial part ordering intact; later files assume project state from earlier parts.
- Route SDK-specific snippets to the C# or Unreal client skills when the question is localized to client API use.
- Route server module schema and reducer edits to table and reducer skills.
