## Format

### Basic file

```yaml
---
- hosts: production
  remote_user: root
  tasks:
  - ···
```

Place your modules inside `tasks`.

### Task formats

#### One-line

```yaml
- apt: pkg=vim state=present
```

#### Map

```yaml
- apt:
    pkg: vim
    state: present
```

#### Foldable scalar

```yaml
- apt: >
    pkg=vim
    state=present    
```

Define your tasks in any of these formats. One-line format is preferred for short declarations, while maps are preferred for longer.
