Select provider [1]:
```

!!! tip "OpenRouter Recommended"
    OpenRouter offers free models and access to 100+ LLMs. Get your API key at [openrouter.ai/keys](https://openrouter.ai/keys)

### Host Discovery

The wizard automatically detects hosts from:

- `~/.ssh/config` - SSH configuration
- `~/.ssh/known_hosts` - Previously connected hosts
- `/etc/hosts` - Local host definitions
- Ansible inventory files

```
Detected inventory sources:
  • SSH Config: 12 hosts
  • Known Hosts: 45 hosts

Import all hosts? [Y/n]:
```

## 2. Manual Configuration (Alternative)

If you skip the wizard or want to change settings later:

=== "Interactive (stores API keys in keyring)"

    ```bash
    merlya
    # then inside the REPL:
    /model provider openrouter
    /model brain amazon/nova-2-lite-v1:free
    ```

=== "CI/CD (API keys via environment variables)"

    ```bash
    export OPENAI_API_KEY="..."
    merlya config set model.provider openai
    merlya config set model.model gpt-4o-mini
    merlya run "Check disk usage on web-01"
    ```

=== "Ollama (local)"

    ```bash
    # First, install Ollama: https://ollama.com
    ollama pull llama3.2

    merlya config set model.provider ollama
    merlya config set model.model llama3.2
    merlya run "Check disk usage on web-01"
    ```

---

## 3. Start the REPL

```bash
merlya
```

Use `/help` to list available commands, and `/exit` to quit.

!!! warning "Experimental Software"
    Always review commands before executing them on production systems.

## 4. Try Some Commands

### Natural Language

- Automating routine DevOps tasks

Just describe what you need in plain English!
```

### Connect to a Server

```
Merlya > Connect to my-server.example.com and show me the uptime

Connecting to my-server.example.com...

> ssh my-server.example.com "uptime"

 14:32:01 up 45 days,  3:21,  2 users,  load average: 0.15, 0.10, 0.05

The server has been running for 45 days with low load averages.
```

### Reference Hosts by Name

```
Merlya > Check disk space on web-01 and web-02

> ssh web-01 "df -h /"
