## What it is
Stateless is a C# library for creating state machines and lightweight state machine-based workflows directly in .NET code. It supports hierarchical states, entry/exit actions, guard clauses, parameterised triggers, and graph export.

## Use cases
- model state machines in C# code
- build lightweight workflow engines in .NET
- implement hierarchical states with entry and exit actions
- add conditional transitions with guard clauses
- export state machine diagrams to DOT or mermaid
- store state machine state externally in an ORM-tracked property

## When to choose
- you need a fluent, in-code state machine for a .NET application
- you want hierarchical states, guards, and parameterised triggers without external tooling
- you need to visualize state machines as DOT or mermaid graphs

## When to avoid
- you need a full BPMN or durable workflow orchestration engine
- your project is not on the .NET platform
- you need distributed or long-running persisted workflows with human tasks

## Facets
- artifact type: library
- maturity: stable
- function: workflow-automation, developer-tools
- domain: developer-tools, cross-platform
- platform: dotnet, cross-platform
