title: Configuring Hugo
weight: 40

The directory structure and templates provide the majority of the
configuration for a site. In fact, a config file isn't even needed for many
websites since the defaults follow commonly used patterns.
Hugo expects to find the config file in the root of the source directory and
will look there first for a `config.toml` file. If none is present, it will
then look for a `config.yaml` file, followed by a `config.json` file.
The config file is a site-wide config. The config file provides directions to
hugo on how to build the site as well as site-wide parameters and menus.
## Examples
The following is an example of a typical yaml config file:
---
baseurl: "http://yoursite.example.com/"
...
The following is an example of a toml config file with some of the default values.
Values under `[params]` will populate the `.Site.Params` variable for use in templates:
contentdir = "content"
layoutdir = "layouts"
publishdir = "public"
builddrafts = false
baseurl = "http://yoursite.example.com/"
canonifyurls = true
[taxonomies]
category = "categories"
tag = "tags"
[params]
description = "Tesla's Awesome Hugo Site"
author = "Nikola Tesla"
Here is a yaml configuration file which sets a few more options:
---
baseurl: "http://yoursite.example.com/"
title: "Yoyodyne Widget Blogging"
footnotereturnlinkcontents: "↩"
permalinks:
post: /:year/:month/:title/
params:
Subtitle: "Spinning the cogs in the widgets"
AuthorName: "John Doe"
GitHubUser: "spf13"
ListOfFoo:
- "foo1"
- "foo2"
SidebarRecentLimit: 5
...
## Configuration variables

publishdir: "public"
# color-codes for highlighting derived from this style
pygmentsStyle: "monokai"
# true: use pygments-css or false: color-codes directly
pygmentsUseClasses: false
# default sitemap configuration map
sitemap:
# filesystem path to read files relative from
source: ""
staticdir: "static"
# display memory and timing of different steps of the program
stepAnalysis: false

themesdir = "themes"
theme: ""
title: ""
# if true, use /filename.html instead of /filename/
uglyURLs: false
# Do not make the url/path to lowercase
disablePathToLower: false
# if true, auto-detect Chinese/Japanese/Korean Languages in the content. (.Summary and .WordCount can work properly in CJKLanguage)
hasCJKLanguage false

# watch filesystem for changes and recreate as needed
watch: true

## Ignore files on build
The following inside `config.toml` will ignore files ending with `.foo` and `.boo` when building with `hugo`:
```
ignoreFiles = [ "\\.foo$", "\\.boo$" ]
```
The above is a list of Regular Expressions, but note the escaping of the `\` to make TOML happy.
## Configure Blackfriday rendering
[Blackfriday](https://github.com/russross/blackfriday) is the [Markdown](http://daringfireball.net/projects/markdown/) rendering engine used in Hugo. The Blackfriday configuration in Hugo is mostly a set of sane defaults that should fit most use cases.
But Hugo does expose some options---as listed in the table below, matched with the corresponding flag in the Blackfriday source ([html.go](https://github.com/russross/blackfriday/blob/master/html.go) and [markdown.go](https://github.com/russross/blackfriday/blob/master/markdown.go)):

**Notes**
1. These flags are **very case-sensitive** (as of Hugo v0.15)!
2. These flags must be grouped under the `blackfriday` key and can be set on **both site and page level**. If set on page, it will override the site setting. Example:
<table class="table">
<thead>
<tr>
<th>TOML</th><th>YAML</th>
</tr>
</thead>
<tbody>
<tr style="vertical-align: top;">
<td style="width: 50%;"><pre><code>[blackfriday]
angledQuotes = true
fractions = false
plainIDAnchors = true
extensions = ["hardLineBreak"]
</code></pre></td>
<td><pre><code>blackfriday:
angledQuotes: true
fractions: false
plainIDAnchors: true
extensions:
- hardLineBreak
</code></pre></td>
</tr>
