In this quickstart, we will build an online bookshelf that will list books and their reviews.
> _Note: This quickstart depends on features introduced in Hugo v0.15. If you have an earlier version of Hugo, you will need to [upgrade](/overview/installing/) before proceeding._
More complete instructions are available at [Installing Hugo]({{< relref "overview/installing.md" >}})
Once `hugo` is installed, make sure to run the `help` command to verify `hugo` installation. Below you can see part of the `help` command output for brevity.
```bash
$ hugo help
```
```
hugo is the main command, used to build your Hugo site.
Hugo is a Fast and Flexible Static Site Generator
built with love by spf13 and friends in Go.
Complete documentation is available at http://gohugo.io/.
```
You can check `hugo` version using the command shown below.
```bash
$ hugo version
```
```

```
## Step 2. Scaffold bookshelf hugo site
Hugo has commands that allows us to quickly scaffold a Hugo managed website. Navigate to a convenient location on your filesystem and create a new Hugo site `bookshelf` by executing the following command.
```bash
$ hugo new site bookshelf
```
Change directory to `bookshelf` and you will see the following directory layout.
```bash
$ tree -a
```
```
.
|-- archetypes
|-- config.toml
|-- content
|-- data
|-- layouts
`-- static
5 directories, 1 file
```
As mentioned in the command output, `bookshelf` directory has 5 sub-directories and 1 file. Let's look at each of them one by one.
* **archetypes**: You can create new content files in Hugo using the `hugo new` command. When you run that command, it adds few configuration properties to the post like date and title. [Archetype]({{< relref "content/archetypes.md" >}}) allows you to define your own configuration properties that will be added to the post front matter whenever `hugo new` command is used.
* **config.toml**: Every website should have a configuration file at the root. By default, the configuration file uses `TOML` format but you can also use `YAML` or `JSON` formats as well. [TOML](https://github.com/toml-lang/toml) is minimal configuration file format that's easy to read due to obvious semantics. The configuration settings mentioned in the `config.toml` are applied to the full site. These configuration settings include `baseurl` and `title` of the website.
* **content**: This is where you will store content of the website. Inside content, you will create sub-directories for different sections. Let's suppose your website has three actions -- `blog`, `article`, and `tutorial` then you will have three different directories for each of them inside the `content` directory. The name of the section i.e. `blog`, `article`, or `tutorial` will be used by Hugo to apply a specific layout applicable to that section.
* **data**: This directory is used to store configuration files that can be used by Hugo when generating your website. You can write these files in YAML, JSON,or TOML format.
* **static**: This directory is used to store all the static content that your website will need like images, CSS, JavaScript or other static content.
## Step 3. Add content
Let's now add a post to our `bookshelf`. We will use the `hugo new` command to add a post. In January, I read [Good To Great](http://www.amazon.com/Good-Great-Some-Companies-Others/dp/0066620996/) book so we will start with creating a post for it. **Make sure you are inside the `bookshelf` directory.**
```bash
$ hugo new post/good-to-great.md
```
```
/Users/shekhargulati/bookshelf/content/post/good-to-great.md created
The content inside `+++` is the TOML configuration for the post. This configuration is called **front matter**. It enables you to define post configuration along with its content. By default, each post will have three configuration properties shown above.
I read **Good to Great in January 2016**. An awesome read sharing detailed analysis on how good companies became great.
```
## Step 4. Serve content
Hugo has an inbuilt server that can serve your website content so that you can preview it. You can also use the inbuilt Hugo server in production. To serve content, execute the following command.
```bash
$ hugo server
```
```
0 of 1 draft rendered
0 future content
0 pages created
0 paginator pages created
0 tags created
0 categories created
in 9 ms
Watching for changes in /Users/shekhargulati/bookshelf/{data,content,layouts,static}
Serving pages from memory
Web Server is available at http://localhost:1313/ (bind address 127.0.0.1)
Press Ctrl+C to stop
```
This will start the server on port `1313`. You can view your blog at http://localhost:1313/. When you will go to the link, you will see nothing. There are couple of reasons for that:
1. As you can see in the `hugo server` command output, Hugo didn't rendered the draft. Hugo will only render drafts if you pass `buildDrafts` flag to the `hugo server` command.
2. We have not specified how Markdown content should be rendered. We have to specify a theme that Hugo can use. We will do that in next step.
To render drafts, re-run the server with command shown below.
```bash
$ hugo server --buildDrafts
```
```
1 of 1 draft rendered
0 future content
1 pages created
0 paginator pages created
0 tags created
0 categories created
in 6 ms
Watching for changes in /Users/shekhargulati/bookshelf/{data,content,layouts,static}
Serving pages from memory
Web Server is available at http://localhost:1313/ (bind address 127.0.0.1)
Press Ctrl+C to stop
```
If you go to [http://localhost:1313/](http://localhost:1313/), you will still not view anything as we have not specified theme that Hugo should use.
## Step 5. Add theme
Themes provide the layout and templates that will be used by Hugo to render your website. There are a lot of Open-source themes available at [https://themes.gohugo.io/](https://themes.gohugo.io/) that you can use.
> **Hugo currently doesn’t ship with a `default` theme, allowing the user to pick whichever theme best suits their project.**
Themes should be added in the `themes` directory inside the website root. Create new directory themes and change directory to it.
```bash
$ mkdir themes && cd themes
```
Now, you can clone one or more themes inside the `themes` directory. We will use robust theme.
FATAL: 2016/02/14 Unable to find theme Directory: /Users/shekhargulati/bookshelf/themes/robust
```
To view your website, you can go to http://localhost:1313/. You will see as shown below.
Let's understand the layout of the theme. A theme consists of following:
* **theme.toml** is the theme configuration file that gives information about the theme like name and description of theme, author details, theme license.
* **images** directory contains two images -- `screenshot.png` and `tn.png`. `screenshot.png` is the image of the list view and `tn.png` is the single post view.
* **layouts** directory contains different views for different content types. Every content type should have two files `single.html` and `list.html`. `single.html` is used for rendering single piece of content. `list.html` is used to view a list of content items. For example, you will use `list.html` to view all the posts with `programming` tag.
* **static** directory stores all the static assets used by the template. Static assets could be JavaScript libraries like jQuery or CSS styles or images or any other static content. This directory will be copied into the final site when rendered.
You can very easily test different layouts by switching between different themes. Let's suppose we want to try out `bleak` theme. We clone `bleak` theme inside the `themes` directory.
Hugo has inbuilt support for live reloading. So, as soon as you save your changes it will apply the change and reload the web page. You will see changes as shown below.
The same is reflected in the Hugo server logs as well. As soon as the configuration is changed, it applied the changes.
Robust theme is a good start towards our online bookshelf but we to customize it a bit to meet the look and feel required for the bookshelf. Hugo makes it very easy to customize themes. You can also create your themes but we will not do that today. If you want to create your own theme, then you should refer to the [Hugo documentation]({{< relref "themes/creation.md" >}}).
The first change that we have to make is to use a different default image instead of the one used in the theme. The default image used in both the list and single view page resides inside the `themes/hugo_theme_robust/static/images/default.jpg`. We can easily replace it by creating a simple directory structure inside the `static` directory inside the `bookshelf` directory.
Now, we need to change the layout of the index page so that only images are shown instead of the text. The index.html inside the layouts directory of the theme refer to partial `li` that renders the list view shown below.
```html
<articleclass="li">
<ahref="{{ .Permalink }}"class="clearfix">
<divclass="image"style="background-image: url({{ $.Site.BaseURL }}images/{{ with .Params.image }}{{ . }}{{ else }}default.jpg{{ end }});"></div>
<divclass="detail">
<time>{{ with .Site.Params.DateForm }}{{ $.Date.Format . }}{{ else }}{{ $.Date.Format "Mon, Jan 2, 2006" }}{{ end }}</time>
<h2class="title">{{ .Title }}</h2>
<divclass="summary">{{ .Summary }}</div>
</div>
</a>
</article>
```
Create a new file li.html inside the `bookshelf/layouts/_default` directory. Copy the content shown below into the li.html. We have removed details of the book so that only image is shown.
```html
<articleclass="li">
<ahref="{{ .Permalink }}"class="clearfix">
<divclass="image"style="background-image: url({{ $.Site.BaseURL }}images/{{ with .Params.image }}{{ . }}{{ else }}default.jpg{{ end }});"></div>
</a>
</article>
```
Now, the website will be rendered as shown below.
Next, we want to remove information related to theme from the footer. So, create a new file inside the `partials/default_foot.html` with the content copied from the theme `partials/default_foot.html`. Replace the footer section with the one shown below.
We also have to remove the sidebar on the right. Copy the index.html from the themes layout directory to the bookshelf layouts directory. Remove the section related to sidebar from the html.
So far we are using the default image but we would like to use the book image so that we can relate to the book. Every book review will define a configuration setting in its front matter. Update the `good-to-great.md` as shown below.
I read **Good to Great in January 2016**. An awesome read sharing detailed analysis on how good companies became great. Although this book is about how companies became great but we could apply a lot of the learnings on ourselves. Concepts like level 5 leader, hedgehog concept, the stockdale paradox are equally applicable to individuals.
So far all the posts that we have written are in draft status. To make a draft public, you can either run a command or manually change the draft status in the post to True.
Disqus allows you to integrate comments in your static blog. To enable Disqus, you just have to set `disqusShortname` in the config.toml as shown below.
