 # Cratis Samples
 
-### Learn the Cratis stack by running real applications
+### Runnable event sourcing and CQRS samples for the Cratis stack
 
-From a small Chronicle process to a React application composed with Arc, Components, and Aspire.
+From a small Chronicle event-sourcing process to a React application composed with Arc, Components, and Aspire — covering the Chronicle event store, Arc CQRS for ASP.NET Core, React Components, the CLI, Workbench, and the model-first Screenplay and Stage (experimental).

 Choose the path matching what you want to learn. The focused samples keep one idea in view; Library brings several paths together in a larger application.
 
+- **Arc** — CQRS for ASP.NET Core: typed commands, observable queries, and TypeScript proxy generation. [Arc documentation](https://www.cratis.io/arc/)
+- **Chronicle** — the event store: append immutable events, then build projections and reactions over the history. [Chronicle documentation](https://www.cratis.io/chronicle/)
+- **Model-first (experimental)** — describe a workflow in a [Screenplay](https://github.com/Cratis/Screenplay) model and let [Stage](https://github.com/Cratis/Stage) render it into a runnable application.

+- **[Chronicle](https://github.com/Cratis/Chronicle)** — event-sourcing database and runtime. Orleans-based kernel, pluggable storage (MongoDB default; PostgreSQL, SQL Server, SQLite, in-memory), language-agnostic gRPC contracts. [Docs](https://www.cratis.io/chronicle/)
+- **Chronicle clients** — first-class [.NET SDK](https://github.com/Cratis/Chronicle), plus [TypeScript](https://github.com/Cratis/Chronicle.TypeScript), [Kotlin/Java](https://github.com/Cratis/Chronicle.Kotlin), and [Elixir](https://github.com/Cratis/Chronicle.Elixir); [Python](https://github.com/Cratis/Chronicle.Python) coming soon (pre-alpha). AI agents connect through the [Chronicle MCP server](https://github.com/Cratis/Chronicle.Mcp).
+- **[Arc](https://github.com/Cratis/Arc)** — opinionated CQRS framework for ASP.NET Core with commands, queries, validation, authorization, and TypeScript proxy generation. Works without event sourcing. [Docs](https://www.cratis.io/arc/)
+- **[Components](https://github.com/Cratis/Components)** — React components aligned with Arc patterns. [Docs](https://www.cratis.io/components/)
+- **[CLI](https://github.com/Cratis/cli) + Workbench** — inspect and diagnose Chronicle from the terminal or the browser. [Docs](https://www.cratis.io/cli/)
+- **Model-first layer (experimental)** — [Studio](https://github.com/Cratis/Studio), [Screenplay](https://github.com/Cratis/Screenplay), [Stage](https://github.com/Cratis/Stage), [Scene](https://github.com/Cratis/Scene), [Prologue](https://github.com/Cratis/Prologue)
