# User Guide

f451 is a wiki whose pages live in Git. Every space you see here is a
repository on Forgejo or GitHub; every page is a Markdown file in it. The
wiki gives you a page tree, full-text search, an editor and a review
workflow on top — but the file in the repository stays the single source
of truth, and its Git history stays the page's history.

Two consequences follow directly from that, and both come up throughout
this guide:

> [!NOTE]
> **Permissions come from Git.** There is no separate role system in
> f451. Whether you can see a space, and whether you can write to it,
> is decided by your permissions in the underlying Forgejo or GitHub
> repository.

> [!NOTE]
> **Nobody writes straight to the published version.** Every change —
> yours, a colleague's, or an AI agent's — goes through a draft and a
> review before it is published. See [[writing-a-page]].

## How this guide is organised

- [[getting-started]] — sign in and connect your Git account
- [[reading-and-navigating]] — the page tree, breadcrumbs, the outline, the phone layout
- [[search-and-graph]] — full-text search, the graph view, the link report
- [[writing-a-page]] — draft, review, approval, and what happens on a conflict
- [[editor-reference]] — formatting, wikilinks, callouts, images, diagrams, video
- [[templates-and-metadata]] — starting points for new pages and structured fields
- [[appearance-and-settings]] — theme, language, connected accounts
- [[ai-agents]] — connecting an AI agent to a space through MCP
- [[faq]] — short answers to recurring questions

If you only read one other page, make it [[getting-started]].
