## Using Templates

To use the templates in the presentation viewer, use the front matter to provide default metadata followed by slide
contents.

The front matter is used to define the default values for the presentation and will be applied to every slides. The
default metadata can be defined as below:

```markdown
---
slide: <default-slide-type>
presenter: <name-of-the-presenter>
logo: <path-to-logo>
color: <font-color-for-slide-title>
footer: <footer-content>
aboutUs:
- title: <about-us-title1>
text: <text-for-title1>

how difficult would it be to allow links here?
Currently

  - title: WWW
     text: [www.jankaritech.com](www.jankaritech.com)

makes the whole presentation to fall apart

Object { name: "YAMLException", reason: "bad indentation of a mapping entry", mark: {…}, message: "bad indentation of a mapping entry at line 7, column 10:\n         text: [www.jankaritech.com](www.jank ... \n             ^", stack: "", … }
​
mark: Object { buffer: "slide: title-content\npresenter:  JankariTech Pvt. Ltd. \nlogo: Logo-colour.png\nfooter: Markdown Presentation Viewer\naboutUs:\n  - title: WWW\n     text: [www.jankaritech.com](www.jankaritech.com)\n  - title: linkedin\n    text: www.linkedin.com/company/jankaritech\n  - title: facebook\n    text: www.facebook.com/jankaritech\n\u0000", position: 148, line: 6, … }

If links are not supported that is fine, but the presentation should not break

Doing something invalid here, e.g text:www.jankaritech.com leads now to this error:

YAMLException: can not read an implicit mapping pair; a colon is missed at line 7, column 29: text:www.jankaritech.com ^

it gives some hint, but might still be hard for users to understand. Do we want to accept that kind of error message for now?

- title: <about-us-title2>
text: <text-for-title2>
- title: <about-us-title3>
text: <text-for-title3>
---
```

These are the supported metadata required for the presentation template.

| Default Metadata | Description |
|------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `slide` | Default slide for presentation. Most used slide template can be given in the default metadata. |
| `presenter` | Name of the presenter. |
| `logo` | Logo appears on the top right corner of the slide. The logo path should be relative to the markdown file. |
| `color` | Font color of the slide title. |
| `footer` | Content to be shown in the footer of the slide. |
| `aboutUs` | Column wise content to be shown in the about-us slide. Use this metadata only if about-us slide is used for the presentation. More [here](#slide-about-us) |
| `aboutUs:title` | Title for each column in about-us slide. |
| `aboutUs:text` | Text under each title for column in about-us slide. |

Following the front matter, create slides as described in [Creating Presentation](#creating-presentation)

Besides default metadata, you can also provide inline metadata for each slide. This will be useful when you want to
override the default metadata for a specific slide and this will be applied to that slide only. The inline metadata can
be defined by adding metadata directly on the slide title as below:

```markdown
# Title of the slide ::metadata_key_1:metadata_value_1 ::metadata_key_2:metadata_value_2
```

Example:
```markdown
# Title of slide ::slide:title-content-image ::logo:logo.png
```

For this slide, the `slide` template will be set to `title-content-image`, and the `logo` will be set to `logo.png`.

### Slide Templates

The slide template should be provided in the default metadata. The slide type set in the default metadata will be used as the default. The mostly used slide template can be set as default. When you set a slide template in the default metadata, you don’t need to specify the slide type again in the inline metadata for slides that are already defined in the default metadata.

| Slide Template | Desctiption | Usage |
|-----------------------|-----------------------------------------------------------------------------------|-------------------------------|
| `cover` | This slide template can be used for cover slide | `::slide:cover` |
| `title-content` | A slide with a title and some content (the content can also be an image) | `::slide:title-content` |
| `title-content-image` | A slide with a title, and content on the left side and an image on the right side | `::slide:title-content-image` |
| `about-us` | The slide with about-us info (e.g., Values, mission, Vision) | `::slide:about-us` |
