**Microbus is the only fabric where every agentic workflow runs on a true microservice substrate.** That single design choice gives your workflows security, scale, observability and prompt-driven authoring that bolt-on workflow engines cannot match.

## Documentation

Full documentation lives at **[docs.microbus.io](https://docs.microbus.io)**, including:

- [Get Started](https://docs.microbus.io/get-started/) — bootstrap a project, take the agent-guided tour, build your first workflow or microservice.

- [Agentic Workflows](https://docs.microbus.io/agentic-workflows/) — multi-step processes with branching, fan-out, human-in-the-loop interrupts, and durable state.

- [Agentic RAD](https://docs.microbus.io/agentic-rad/) — how coding agents drive Microbus development end to end.

- [Microservice Substrate](https://docs.microbus.io/microservice-substrate/) — the production-grade fabric the workflows run on.

- [Security in Depth](https://docs.microbus.io/security-in-depth/) — the layered security model.

- [Package Reference](https://docs.microbus.io/package-reference/) — every package's role and exported API.

- [Release Notes](https://docs.microbus.io/about/release-notes/) — per-release changes.

## Quick Start

You'll need a coding agent (e.g. Claude Code), [Go](https://go.dev/) 1.26+, [NATS](https://nats.io), and a SQL database for [agentic workflow](https://docs.microbus.io/agentic-workflows/) state. Then:

```sh

mkdir -p myproject

cd myproject

```

Ask your coding agent to bootstrap Microbus:

> curl the workflow at microbus.io/bootstrap and follow it

The agent walks through the bootstrap, sets up `.claude/` rules and skills, scaffolds the project, and verifies the build. See [Get Started](https://docs.microbus.io/get-started/) for the full walkthrough.
