# go-help

Display-agnostic help content management library. Provides a YAML/Markdown topic catalogue, full-text search with inverted index, stemming, fuzzy matching, and relevance scoring, goldmark-based Markdown rendering, an HTTP server with six routes (three HTML, three JSON), a static site generator with client-side JavaScript search, and CLI help text ingestion. No runtime dependency on a database, network, or external service.

**Module**: `forge.lthn.ai/core/go-help`
**Licence**: EUPL-1.2
**Language**: Go 1.25

## Quick Start

```go
import "forge.lthn.ai/core/go-help"

catalog := help.DefaultCatalog()
catalog.Add(&help.Topic{ID: "rate-limiting", Title: "Rate Limiting", Content: "..."})

// Search
results := catalog.Search("sliding window token")

// HTTP server (HTML + JSON routes)
srv := help.NewServer(catalog, ":8080")
srv.ListenAndServe()

// Static site output
help.Generate(catalog, "./dist")
```
