# Documentation

Start with the five-minute quickstart. If you know git, the Rosetta stone will make sgit feel familiar in one read.

## Introduction

[What is sgitThe pitch, the mechanism, the architecture](what-is-sgit.md) [Installationpip install, verify, upgrade](installation.md) [QuickstartCreate, commit, push, clone — in 5 minutes](quickstart.md)

## Concepts

[sgit for git usersThe Rosetta stone: same verbs, three differences](sgit-for-git-users.md) [The two-branch modelClone branches, named branches, and why](two-branch-model.md) [The security modelWhat the server sees; the crypto stack](../security/index.md) [Keys and signaturesEncrypting to someone who holds no vault key](pki.md)

## Messaging & the API

[Sending messages between vaultsAppend lanes + PKI, composed into a worked example](vault-messaging.md) [The HTTP APIEndpoints, headers, gates, limits and error codes](../api/index.md) [Append lanesThe write-only transport behind vault messaging](../api/append-lanes.md)

## Guides

[Working with AI agentswrite, --json, sparse clones, multi-agent patterns](agents.md) [Use casesFive workflows, all on shipped commands](../use-cases/index.md) [SG/Vault platformThe browser app, vault apps, the window.sg bridge](../vault/index.md)

## Project

[When NOT to use sgitThe honest page](limitations.md) [Why does this exist?Answering the no-market criticism, plus a FAQ](../why/index.md) [If a vault key is exposedThe rotation runbook, with a real case study](../case-studies/exposed-vault-key.md) [Cross-team briefsOpen asks to the CLI and API teams](../briefs/index.md) [Admin & engineeringHow this site is built and released](../admin/index.md) [GitHubSource, issues, changelog](https://github.com/SGit-AI/SGit-AI__CLI)

**Coming next:** a full per-command CLI reference, generated directly from the CLI's own argument parser on every release — so the reference can never drift from the shipped tool.
