## Configuration File
Hugo uses the `config.toml`, `config.yaml`, or `config.json` (if found in the
site root) as the default site config file.
The user can choose to override that default with one or more site config files
using the command line `--config` switch.
Examples:
```
hugo --config debugconfig.toml
hugo --config a.toml,b.toml,c.toml
```
{{% note %}}
Multiple site config files can be specified as a comma-separated string to the `--config` switch.
{{% /note %}}
{{< todo >}}TODO: distinct config.toml and others (the root object files){{< /todo >}}
## Configuration Directory
In addition to using a single site config file, one can use the `configDir` directory (default to `config/`) to maintain easier organization and environment specific settings.
- Each file represents a configuration root object, such as `params.toml` for `[Params]`, `menu(s).toml` for `[Menu]`, `languages.toml` for `[Languages]` etc...
- Each file's content must be top-level, for example:
{{< code-toggle file="config" >}}
[Params]
foo = "bar"
{{< /code-toggle >}}
{{< code-toggle file="params" >}}
foo = "bar"
{{< /code-toggle >}}
- Each directory holds a group of files containing settings unique to an environment.
- Files can be localized to become language specific.
```
├── config
│ ├── _default
│ │ ├── config.toml
│ │ ├── languages.toml
│ │ ├── menus.en.toml
│ │ ├── menus.zh.toml
│ │ └── params.toml
│ ├── production
│ │ ├── config.toml
│ │ └── params.toml
│ └── staging
│ ├── config.toml
│ └── params.toml
```
Considering the structure above, when running `hugo --environment staging`, Hugo will use every settings from `config/_default` and merge `staging`'s on top of those.
{{% note %}}
Default environments are __development__ with `hugo server` and __production__ with `hugo`.
{{%/ note %}}
## Merge Configuration from Themes
{{< new-in "0.84.0" >}} The configuration merge described below was improved in Hugo 0.84.0 and made fully configurable. The big change/improvement was that we now, by default, do deep merging of `params` maps from themes.
The configuration value for `_merge` can be one of:
none
: No merge.
shallow
: Only add values for new keys.
deep
: Add values for new keys, merge existing.
Note that you don't need to be so verbose as in the default setup below; a `_merge` value higher up will be inherited if not set.
{{< code-toggle config="mergeStrategy" skipHeader=true />}}
## All Configuration Settings
The following is the full list of Hugo-defined variables with their default
value in parentheses. Users may choose to override those values in their site
config file(s).

Include content with publishdate in the future.
### caches
See [Configure File Caches](#configure-file-caches)
### cascade
{{< new-in "0.86.0" >}}
Pass down down default configuration values (front matter) to pages in the content tree. The options in site config is the same as in page front matter, see [Front Matter Cascade](/content-management/front-matter#front-matter-cascade).
### canonifyURLs

Render the default content language in subdir, e.g. `content/en/`. The site root `/` will then redirect to `/en/`.
### disableAliases
**Default value:** false

### disableHugoGeneratorInject
**Default value:** false
Hugo will, by default, inject a generator meta tag in the HTML head on the _home page only_. You can turn it off, but we would really appreciate if you don't, as this is a good way to watch Hugo's popularity on the rise.
### disableKinds
**Default value:** []
Enable disabling of all pages of the specified *Kinds*. Allowed values in this list: `"page"`, `"home"`, `"section"`, `"taxonomy"`, `"term"`, `"RSS"`, `"sitemap"`, `"robotsTXT"`, `"404"`.
### disableLiveReload

### enableGitInfo
**Default value:** false
Enable `.GitInfo` object for each page (if the Hugo site is versioned by Git). This will then update the `Lastmod` parameter for each page using the last git commit date for that content file.
### enableInlineShortcodes
**Default value:** false
Enable inline shortcode support. See [Inline Shortcodes](/templates/shortcode-templates/#inline-shortcodes).
### enableMissingTranslationPlaceholders
**Default value:** false
Show a placeholder instead of the default value or an empty string if a translation is missing.
### enableRobotsTXT

**Default value:** ""
Prefix for footnote anchors.
### footnoteReturnLinkContents
**Default value:** ""
Text to display for footnote return links.
### googleAnalytics
**Default value:** ""
Google Analytics tracking ID.
### hasCJKLanguage
**Default value:** false

### languageCode
**Default value:** ""
A language tag as defined by [RFC 5646](https://datatracker.ietf.org/doc/html/rfc5646). The internal [RSS template](https://github.com/gohugoio/hugo/blob/master/tpl/tplimpl/embedded/templates/_default/rss.xml) populates its `<language>` element with this value. The value is not used elsewhere.

### refLinksErrorLevel
**Default value:** "ERROR"

The directory where Hugo reads the themes from.
### timeout
**Default value:** "30s"
Timeout for generating page contents, specified as a [duration](https://pkg.go.dev/time#Duration) or in milliseconds. *Note:* this is used to bail out of recursive content generation. You might need to raise this limit if your pages are slow to generate (e.g., because they require large image processing or depend on remote contents).
### timeZone
{{< new-in "0.87.0" >}}
The time zone (or location), e.g. `Europe/Oslo`, used to parse front matter dates without such information and in the [`time` function](/functions/time/). The list of valid values may be system dependent, but should include `UTC`, `Local`, and any location in the [IANA Time Zone database](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones).
### title
Site title.
### titleCaseStyle
**Default value:** "AP"

### uglyURLs
When enabled, creates URL of the form `/filename.html` instead of `/filename/`.
### watch
Watch filesystem for changes and recreate as needed.
{{% note %}}
If you are developing your site on a \*nix machine, here is a handy shortcut for finding a configuration option from the command line:
```
cd ~/sites/yourhugosite
hugo config | grep emoji
```
which shows output like
```
enableemoji: true
```
{{% /note %}}
## Configure Build
{{< new-in "0.66.0" >}}
The `build` configuration section contains global build-related configuration options.
{{< code-toggle file="config">}}
[build]
useResourceCacheWhen="fallback"
writeStats = false
noJSConfigInAssets = false
{{< /code-toggle >}}
useResourceCacheWhen
: When to use the cached resources in `/resources/_gen` for PostCSS and ToCSS. Valid values are `never`, `always` and `fallback`. The last value means that the cache will be tried if PostCSS/extended version is not available.
writeStats {{< new-in "0.69.0" >}}
: When enabled, a file named `hugo_stats.json` will be written to your project root with some aggregated data about the build, e.g. list of HTML entities published to be used to do [CSS pruning](/hugo-pipes/postprocess/#css-purging-with-postcss). If you're only using this for the production build, you should consider placing it below [config/production](/getting-started/configuration/#configuration-directory). It's also worth mentioning that, due to the nature of the partial server builds, new HTML entities will be added when you add or change them while the server is running, but the old values will not be removed until you restart the server or run a regular `hugo` build.
**Note** that the prime use case for this is purging of unused CSS; it is build for speed and there may be false positives (e.g. elements that isn't really a HTML element).
