# Quick Start

> Install Brain OS and run your first skill in under five minutes.

<Note>
  Brain OS requires [Claude Code](https://docs.anthropic.com/en/docs/agents-and-tools/claude-code/overview). Install and authenticate Claude Code before continuing.
</Note>

<Steps>
  <Step title="Install Brain OS">
    The fastest way to install all 25 skills is the one-line curl installer:

    ```bash theme={null}
    curl -sSL https://raw.githubusercontent.com/sonthanh/brain-os-plugin/main/skills.sh | bash
    ```

    This clones the plugin to `~/.brain-os/` and symlinks all skills to `~/.claude/skills/`.

    <Tip>
      The Claude Code Marketplace gives you managed installs and one-command updates. Use it if you prefer not to run curl scripts directly:

      ```bash theme={null}
      /plugin marketplace add sonthanh/brain-os-marketplace
      /plugin install brain-os@brain-os-marketplace
      ```
    </Tip>
  </Step>

  <Step title="Set your vault path">
    Open `~/.brain-os/brain-os.config.md` and set `vault_path` to the location of your Obsidian vault:

    ```yaml theme={null}
    vault_path: /path/to/your/obsidian/vault
    ```

    Every Brain OS skill reads this file to locate your vault. If this is not set correctly, skills will not find your notes.

    See [Vault Setup](/vault-setup) for the expected folder structure inside your vault.
  </Step>

  <Step title="Run your first skill">
    Open Claude Code and run:

    ```bash theme={null}
    /today
    ```

    The `today` skill reads your calendar, open tasks, and recent notes to generate a prioritized plan for the day. It's a good first skill because it works immediately with whatever notes you already have.
  </Step>

  <Step title="Install specific skills only">
    If you only want a subset of skills, pass them as arguments to the installer:

    ```bash theme={null}
    curl -sSL https://raw.githubusercontent.com/sonthanh/brain-os-plugin/main/skills.sh | bash -s self-learn audit today
    ```

    This installs only `self-learn`, `audit`, and `today` — leaving your `~/.claude/skills/` directory untouched otherwise.
  </Step>

  <Step title="Uninstall">
    To remove all Brain OS skills:

    ```bash theme={null}
    curl -sSL https://raw.githubusercontent.com/sonthanh/brain-os-plugin/main/skills.sh | bash -s -- --uninstall
    ```

    This removes all Brain OS symlinks from `~/.claude/skills/`. Your vault and config file are left untouched.
