# MantleOS > Self-hosted AI brain: one structured memory (seven layers, one Postgres) that > ingests your email, files, notes, and conversations, with an autonomous > assistant living inside it. Self-hosted software, not a hosted service; > one brain per install. Dual-licensed FSL-1.1-MIT + commercial. ## Install - [AI installation runbook](https://mantleos.io/ai-install.md): the authoritative agent-oriented install procedure: requirements, the two compose projects (brain + MantleOS owner UI), the env-var contract (`MANTLE_YES=1` for a silent install, `MANTLE_DOMAIN` for HTTPS, `MANTLE_CHANNEL`, sandboxes, media, local embedder), domain-vs-IP, Caddy pointing, health checks. - One-liner: `curl -fsSL https://raw.githubusercontent.com/crossworks-engineering/mantle/main/install.sh | bash` (prompts when a terminal exists; agents set `MANTLE_YES=1`) - Requirements: a Linux box with Docker Engine and the compose plugin; more than 4 GB RAM for the full stack, 4 GB fits the core shape. ## The client - [MantleOS Desktop](https://mantleos.io/desktop/): the owner UI, web and desktop, in its own repository at https://github.com/crossworks-engineering/jackdaw - [Desktop downloads](https://github.com/crossworks-engineering/jackdaw/releases): Linux, macOS (unsigned today) and Windows ## Docs - [Repository](https://github.com/crossworks-engineering/mantle) - [Self-hosting](https://github.com/crossworks-engineering/mantle/blob/main/docs/self-hosting.md) - [Getting started](https://github.com/crossworks-engineering/mantle/blob/main/docs/getting-started.md) - [Architecture](https://github.com/crossworks-engineering/mantle/blob/main/docs/architecture.md) - [Licensing, plain language](https://github.com/crossworks-engineering/mantle/blob/main/LICENSING.md)
