-The same generator also ships as an MCP server — `npx -y -p nativeapptemplate-agent nativeapptemplate-agent-mcp` exposes a `generate_app` tool, so any MCP-capable assistant (Claude Code, Cursor, Cline, Goose) can invoke it without leaving the editor. And a **Claude Code plugin** ships in [`plugin/`](./plugin/) — `claude --plugin-dir ./plugin` loads two skills: `/nativeapptemplate-agent:generate-app` (generate → validate → explain) and `/nativeapptemplate-agent:walk-app` (launch the app on a simulator/emulator and walk its UI via `mobile-mcp`, screenshots inline).

-## Install from git
+## Install from the marketplace
+
+The repo ships a marketplace manifest (`.claude-plugin/marketplace.json`) that points at
+this `plugin/` directory. Add the marketplace, then install:
 
 ```
-/plugin install github.com/nativeapptemplate/nativeapptemplate-agent
+/plugin marketplace add nativeapptemplate/nativeapptemplate-agent
+/plugin install nativeapptemplate-agent@nativeapptemplate
 ```
 
-> Note: the plugin lives in the `plugin/` subdirectory of the repo. If installing
-> by path, point at `plugin/`, not the repo root.
+`nativeapptemplate` is the marketplace name; `nativeapptemplate-agent` is the plugin. Once
+installed, the skills are available as `/nativeapptemplate-agent:generate-app` and
+`/nativeapptemplate-agent:walk-app` (and `/mcp` shows both bundled servers). The CLI forms
+are `claude plugin marketplace add nativeapptemplate/nativeapptemplate-agent` and
+`claude plugin install nativeapptemplate-agent@nativeapptemplate`.
