### Optional Parameters

| Parameters | Types | Specifications |
|:---------- |:----- |:-------------- |
| `author`   | string | The author name of the site; It would be showed in the copyright statement. |
| `skin`     | string | The skin name. See more information on the [Customization](#customization) section. |
| `lang`     | string | The language of the site; The default value is `en`. |
| `paginate` | int    | The number of posts on each page. To enable pagination, you must use a third-party plugin, e.g. [`jekyll-paginate`](https://github.com/jekyll/jekyll-paginate), [`jekyll-paginate-v2`](https://github.com/sverrirs/jekyll-paginate-v2), or [`jekyll-pagination`](https://github.com/prometheus-ev/jekyll-pagination). |

## Archive Pages

Hamilton implements some archive templates in pure Liquid. For example, if you want to create a category archive page, set the below parameters on that page:

```yml
---
layout: archive-taxonomies
type: categories
---
```

Or a tag archive page:

```yml
layout: archive-taxonomies
type: tags
```

Or archive by years:

```yml
layout: archive-years
```

## MathJax

You can enable MathJax on each post or page, just set `math: true` on that page.

## Customization

### Metadata

You can create a file `_includes/custom-head.html` in your repository, and add any metadata into that page, e.g. favicons.

### Navigation

You can create a file `_data/navigation.yml` to configure links to some pages. For example,

```yml
- title: About
  url: /about/
- title: Categories
  url: /categories/
- title: Tags
  url: /tags/
```

### Social Media

You can create a file `_data/social.yml` to configure links to your social media. For example,

```yml
- title: Twitter
  url: https://twitter.com/ngzhio
  icon: fab fa-twitter
- title: GitHub
  url: https://github.com/ngzhio/jekyll-theme-hamilton
  icon: fab fa-github
```

### Skins

You can select a skin by setting `skin` in `_config.yml`. The built-in skins include `daylight`, `midnight`, `sunrise`, and `sunset`. If you don't specify any skin, Hamilton would dynamically select one in these built-in skins according to different hours in a day.

You can also customize a new skin, for example, a skin called `solarized`. You need to copy [`_sass/hamilton/skins/daylight.scss`](_sass/hamilton/skins/daylight.scss) into your repository and then rename it to `solarized.scss`, and adjust some colors in that file. Finally, specify `skin: solarized` in `_config.yml`.

### More Customized Styles

If you want to create more CSS styles in your site, creating a file `_sass/hamilton/custom-styles.scss`, and putting your code in there, Hamilton would automatically refer to them.
