# {unit_name}

Two-sentence summary of the code unit.

## Introduction

Prose covering the purpose and application of the unit, the key classes that
depend on it, and the developer problems it solves.

## Get started

A single minimal implementation demonstrating the unit, with enough of the
surrounding classes to show where the call belongs. Omit top-level imports and
main() runner boilerplate to keep the code snippet focused.

## How it works

How the unit accomplishes its purpose from a caller's perspective, the classes
it depends on, the classes that depend on it, and the cross-class interactions a
caller will notice. Do not discuss internal implementation details (such as
private methods, internal data structures, or unexported helpers).

## Configuration options

A table of the options the unit itself introduces:

| Option | Type | Default | Description |
| :--- | :--- | :--- | :--- |
| `{option}` | `{type}` | `{default}` | What it controls. |

Follow the table with a paragraph per option covering real behaviour and usage
patterns, not a restatement of the type. Omit options inherited from a base
class, never include private attributes, and do not enumerate every attribute
and method — exhaustive API reference belongs in the generated reference
documentation.

## Advanced applications

Use cases beyond the minimum: the problem each solves and the implementation
for that circumstance. Omit the section when there are none.

## Limitations

Known limits of the unit.
