# Install

> Three install paths for the open-source substrate

The substrate is the open-source [ai-brain-starter](https://github.com/mycelium-hq/ai-brain-starter) repo. Three install paths, ordered from least to most technical.

## Paste-prompt for Claude Code

Easiest path. Paste the install prompt into a fresh Claude Code session and let the harness scaffold the vault for you.

```
Install ai-brain-starter into ~/Documents/MyVault.
Read the README at github.com/mycelium-hq/ai-brain-starter and follow it end to end.
```

Claude reads the public README, clones the repo, and runs `bootstrap.sh` (macOS / Linux) or `bootstrap.ps1` (Windows). Takes about three minutes.

## Plugin marketplace

If you already use the Claude Code plugin marketplace, search for `ai-brain-starter` and install. The marketplace handles cloning and registering hooks.

## Manual git clone

For operators who want full control:

```bash theme={null}
git clone https://github.com/mycelium-hq/ai-brain-starter ~/Documents/MyVault
cd ~/Documents/MyVault
./bootstrap.sh
```

The bootstrap script:

1. Creates the vault folder structure (`Meta/`, `Sessions/`, `External Inputs/`).
2. Writes a starter `CLAUDE.md` with placeholders.
3. Registers the `~/.claude/hooks/` and `~/.claude/skills/` symlinks.
4. Prompts you for tenant context (name, role, email).

After install, open the vault in Obsidian and run `/diagnose` from a Claude Code session to verify the install passed every check.

## Paid runtime

The hosted runtime (per-tenant JWTs, audit log, webhook receivers, RBAC, dashboards) is a paid layer on top of the open-source substrate. See [/byoc](/self-host/byoc) for self-host or contact us at the [marketing site](https://myceliumai.co) for the managed offering.
