## Installation

Minimal Mistakes now requires [Jekyll](http://jekyllrb.com/) 2.2+. Make sure to run `gem update jekyll` if you aren't on the latest version or `gem install jekyll` if this is your first time installing it.

If you are creating a new Jekyll site using Minimal Mistakes follow these steps:

1. Fork the [Minimal Mistakes repo](http://github.com/mmistakes/minimal-mistakes/fork).
2. Clone the repo you just forked and rename it.
3. [Install Bundler](http://bundler.io) `gem install bundler` and Run `bundle install` to install all dependencies (Jekyll, [Jekyll-Sitemap](https://github.com/jekyll/jekyll-sitemap), [Octopress](https://github.com/octopress/octopress), etc)
4. Update `config.yml`, add navigation, and replace demo posts and pages with your own. Full details below.

If you want to use Minimal Mistakes with an existing Jekyll site follow these steps:

1. [Download Minimal Mistakes](https://github.com/mmistakes/minimal-mistakes/archive/master.zip) and unzip.
2. Rename `minimal-mistakes-master` to something meaningful ie: `new-site`
3. Run `bundle install` to install all dependencies (Jekyll, [Jekyll-Sitemap](https://github.com/jekyll/jekyll-sitemap), [Octopress](https://github.com/octopress/octopress), etc)
4. Remove demo posts/pages and replace with your own posts, pages, and any other content you want to move over.
5. Update posts' and pages' YAML to match variables used by Minimal Mistakes. Full details below.
6. Update `_config.yml` and add navigation links. Full details below.

**Pro-tip:** Delete the `gh-pages` branch after cloning and start fresh by branching off `master`. There is a bunch of garbage in `gh-pages` used for the theme's demo site that I'm guessing you won't want.

## Running Jekyll

If `jekyll build` and `jekyll serve` throw errors you may have to run Jekyll with `bundled exec` instead.

> In some cases, running executables without bundle exec may work, if the executable happens to be installed in your system and does not pull in any gems that conflict with your bundle.
>
>However, this is unreliable and is the source of considerable pain. Even if it looks like it works, it may not work in the future or on another machine.

## Scaffolding

How Minimal Mistakes is organized and what the various files are. All posts, layouts, includes, stylesheets, assets, and whatever else is grouped nicely under the root folder. The compiled Jekyll site outputs to `_site/`.

## Site Setup

A quick checklist of the files you'll want to edit to get up and running.

### Site Wide Configuration

`_config.yml` is your friend. Open it up and personalize it. Most variables are self explanatory but here's an explanation of each if needed:

#### title

The title of your site... shocker!

Example `title: My Awesome Site`

#### url

Used to generate absolute urls in `sitemap.xml`, `feed.xml`, and for generating canonical URLs in `<head>`. When developing locally either comment this out or use something like `http://localhost:4000` so all assets load properly. *Don't include a trailing `/`*.

Examples:

{% highlight yaml %}
url: http://mmistakes.github.io/minimal-mistakes
url: http://localhost:4000
url: //cooldude.github.io
url:
{% endhighlight %}

#### Google Analytics and Webmaster Tools

Google Analytics UA and Webmaster Tool verification tags can be entered under `owner` in `_config.yml`. For more information on obtaining these meta tags check [Google Webmaster Tools](http://support.google.com/webmasters/bin/answer.py?hl=en&answer=35179) and [Bing Webmaster Tools](https://ssl.bing.com/webmaster/configure/verify/ownership) support.

### Navigation Links

To set what links appear in the top navigation edit `_data/navigation.yml`. Use the following format to set the URL and title for as many links as you'd like. *External links will open in a new window.*

{% highlight yaml %}
- title: Portfolio
  url: /portfolio/

- title: Made Mistakes
  url: http://mademistakes.com
{% endhighlight %}

## Adding New Content with Octopress

While completely optional, I've included Octopress and some starter templates to automate the creation of new posts and pages. To take advantage of it start by installing the [Octopress](https://github.com/octopress/octopress) gem if it isn't already.

{% highlight bash %}
$ gem install octopress
{% endhighlight %}

### New Post

Default command

{% highlight bash %}
$ octopress new post "Post Title"
{% endhighlight %}

Default works great if you want all your posts in one directory, but if you're like me and want to group them into subfolders like `/posts`, `/portfolio`, etc. Then this is the command for you. By specifying the DIR it will create a new post in that folder and populate the `categories:` YAML with the same value.

{% highlight bash %}
$ octopress new post "New Portfolio Post Title" --dir portfolio
{% endhighlight %}

### New Page

To create a new page use the following command.

{% highlight bash %}
$ octopress new page new-page/
{% endhighlight %}

This will create a page at `/new-page/index.md`

## Layouts and Content

Explanations of the various `_layouts` included with the theme and when to use them.

### Post and Page

These two layouts are very similar. Both have an author sidebar, allow for large feature images at the top, and optional Disqus comments. The only real difference is the post layout includes related posts at the end of the page.

### Post Index Page

A [sample index page]({{ site.url }}/posts/) listing all posts grouped by the year they were published has been provided. The name can be customized to your liking by editing a few references. For example, to change **Posts** to **Writing** update the following:

* In `_config.yml` under `links:` rename the title and URL to the following:
{% highlight yaml %}
  links:
  - title: Writing
    url: /writing/
{% endhighlight %}
* Rename `posts/index.md` to `writing/index.md` and update the YAML front matter accordingly.
* Update the **View all posts** link in the `post.html` layout found in `_layouts` to match title and URL set previously.

### Feature Images

A good rule of thumb is to keep feature images nice and wide so you don't push the body text too far down. An image cropped around around 1024 x 256 pixels will keep file size down with an acceptable resolution for most devices. If you want to serve these images responsively I'd suggest looking at the [Jekyll Picture Tag](https://github.com/robwierzbowski/jekyll-picture-tag) plugin[^plugins].

[^plugins]: If you're using GitHub Pages to host your site be aware that plugins are disabled. You'll need to build your site locally and then manually deploy if you want to use this sweet plugin.

The post and page layouts make the assumption that the feature images live in the `images/` folder. To add a feature image to a post or page just include the filename in the front matter like so. It's probably best to host all your images from this folder, but you can hotlink from external sources if you desire.

{% highlight yaml %}
image:
  feature: feature-image-filename.jpg
  thumb: thumbnail-image.jpg #keep it square 200x200 px is good
{% endhighlight %}

To add attribution to a feature image use the following YAML front matter on posts or pages. Image credits appear directly below the feature image with a link back to the original source if supplied.

{% highlight yaml %}
image:
  feature: feature-image-filename.jpg
  credit: Michael Rose #name of the person or site you want to credit
  creditlink: http://mademistakes.com #url to their site or licensing
{% endhighlight %}

### Thumbnails for OG and Twitter Cards

Feature and thumbnail images are used by [Open Graph](https://developers.facebook.com/docs/opengraph/) and [Twitter Cards](https://dev.twitter.com/docs/cards) as well. If you don't assign a thumbnail the default graphic *(default-thumb.png)* is used. I'd suggest changing this to something more meaningful --- your logo or avatar are good options.

**Pro-Tip**: You need to [apply for Twitter Cards](https://dev.twitter.com/docs/cards) before they will begin showing up when links to your site are shared.

### Author Override

By making use of data files you can assign different authors for each post.

Start by modifying `authors.yml` file in the `_data` folder and add your authors using the following format.

{% highlight yaml %}
# Authors

billy_rick:
  name: Billy Rick
  web: http://thewhip.com
  email: billy@rick.com
  bio: "What do you want, jewels? I am a very extravagant man."
  avatar: bio-photo-2.jpg
  twitter: extravagantman
  google:
    plus: +BillyRick

cornelius_fiddlebone:
  name: Cornelius Fiddlebone
  email: cornelius@thewhip.com
  bio: "I ordered what?"
  avatar: bio-photo.jpg
  twitter: rhymeswithsackit
  google:
    plus: +CorneliusFiddlebone
{% endhighlight %}

To assign Billy Rick as an author for our post. We'd add the following YAML front matter to a post:

{% highlight yaml %}
author: billy_rick
{% endhighlight %}

### Kramdown Table of Contents

To include an auto-generated **table of contents** for posts and pages, add the following `_include` before the actual content. [Kramdown will take care of the rest](http://kramdown.rubyforge.org/converter/html.html#toc) and convert all headlines into list of links.

{% highlight html %}
{% raw %}{% include _toc.html %}{% endraw %}
{% endhighlight %}

### Paragraph Indentation

By default the margin below paragraphs has been removed and indent added to each. This is an intentional design decision to mimic the look of type set in a printed book or manuscript.

<figure>
  <img src="{{ site.url }}/images/paragraph-indent.png" alt="screen shot of paragraphs with default indent style set">
  <figcaption>Example of the default paragraph style (indented first line and bottom margin removed).</figcaption>
</figure>

To disable the indents and add spacing between paragraphs change the following line in `_sass/variables.scss` from `true !default` to `false` like so.

{% highlight css %}
$paragraph-indent: false;
{% endhighlight %}

<figure>
  <img src="{{ site.url }}/images/paragraph-no-indent.png" alt="screen shot of paragraphs with indent style disabled">
  <figcaption>Example of paragraphs with $paragraph-indent disabled.</figcaption>
</figure>

### Videos

Video embeds are responsive and scale with the width of the main content block with the help of [FitVids](http://fitvidsjs.com/).

Not sure if this only effects Kramdown or if it's an issue with Markdown in general. But adding YouTube video embeds causes errors when building your Jekyll site. To fix add a space between the `<iframe>` tags and remove `allowfullscreen`. Example below:

{% highlight html %}
<iframe width="560" height="315" src="http://www.youtube.com/embed/PWf4WUoMXwg" frameborder="0"> </iframe>
{% endhighlight %}

### Social Sharing Links

Social sharing links for Twitter, Facebook, and Google+ are included on posts/pages by default. To hide them on specific posts or pages add `share: false` to the YAML Front Matter. If you'd like to use different social networks modify `_includes/_social-share.html` to your liking. Icons are set using [Font Awesome](http://fontawesome.io).

## Further Customization

Jekyll 2.x added support for Sass files making it much easier to modify a theme's fonts and colors. By editing values found in `_sass/variables.scss` you can fine tune the site's colors and typography.

For example if you wanted a red background instead of white you'd change `$bodycolor: #fff;` to `$bodycolor: $cc0033;`.

To modify the site's JavaScript files I setup a Grunt build script to lint/concatenate/minify all scripts into `scripts.min.js`. [Install Node.js](http://nodejs.org/), then [install Grunt](http://gruntjs.com/getting-started), and then finally install the dependencies for the theme contained in `package.json`:

{% highlight bash %}
npm install
{% endhighlight %}

From the theme's root, use `grunt` concatenate JavaScript files, and optimize .jpg, .png, and .svg files in the `images/` folder. You can also use `grunt dev` in combination with `jekyll build --watch` to watch for updates JS files that Grunt will then automatically re-build as you write your code which will in turn auto-generate your Jekyll site when developing locally.
