 These docs describe the MendCode-owned product surface: the public `mendcode` CLI, `.mendcode/` configuration, setup flow, runtime packages, model roles, prompt modes, memory, permissions, TUI customization, Plan Mode, Changes Review, Loop Workflows, Usage Insights, mflow, optional TSM/worktrees, and release/security policy.
 
-If you are deciding what to show on GitHub or the website, start with [Feature Map](features.md). If you only read one setup page after this index, read [CLI, setup, and configuration](cli-setup-configuration.md). If you are shaping the visual product experience, read [Customization](customization.md).
+Use this index by intent. **Use MendCode** explains the public workflow, **Features and pages** describes what the TUI can do, and **Build and maintain** is for packages, extensions, source paths, and releases. The [Source Map](source-map.md) is intentionally separate so normal product docs do not repeat internal `opencode` paths.

The runtime source lives in `src/mendcode/packages/opencode`, but public commands are routed through MendCode modules under `src/mendcode/packages/opencode/src/mend`.
