+## Configure Markup
+
+{{< new-in "0.60.0" >}}
+
+See [Goldmark](#goldmark) for settings related to the default Markdown handler in Hugo.
+
+Below are all markup related configuration in Hugo with their default settings:
+
+{{< code-toggle config="markup" />}}
+
+**See each section below for details.**
+
+### Goldmark
+
+[Goldmark](https://github.com/yuin/goldmark/) is from Hugo 0.60 the default library used for Markdown. It's fast, it's [CommonMark](https://spec.commonmark.org/0.29/) compliant and it's very flexible. Note that the feature set of Goldmark vs Blackfriday isn't the same; you gain a lot but also lose some, but we will work to bridge any gap in the upcoming Hugo versions.
+
+This is the default configuration:
+
+{{< code-toggle config="markup.goldmark" />}}
+
+For details on the extensions, refer to [this section](https://github.com/yuin/goldmark/#built-in-extensions) of the Goldmark documentation
+
+Some settings explained:
+
+unsafe
+: By default, Goldmark does not render raw HTMLs and potentially dangerous links. If you have lots of inline HTML and/or JavaScript, you may need to turn this on.
+
+typographer
+: This extension substitutes punctuations with typographic entities like [smartypants](https://daringfireball.net/projects/smartypants/).
+
+attribute
+: Enable custom attribute support for titles and blocks by adding attribute lists inside single curly brackets (`{.myclass class="class1 class2" }`) and placing it _after the Markdown element it decorates_, on the same line for titles and on a new line directly below for blocks.
+
+{{< new-in "0.81.0" >}} In Hugo 0.81.0 we added support for adding attributes (e.g. CSS classes) to Markdown blocks, e.g. tables, lists, paragraphs etc.
+
+A blockquote with a CSS class:
+
+```md
+> foo
+> bar
+{.myclass}
+```
+
+There are some current limitations: For tables you can currently only apply it to the full table, and for lists the `ul`/`ol`-nodes only, e.g.:
+
+```md
+* Fruit
+  * Apple
+  * Orange
+  * Banana
+  {.fruits}
+* Dairy
+  * Milk
+  * Cheese
+  {.dairies}
+{.list}
+```
+
+Note that attributes in [code fences](/content-management/syntax-highlighting/#highlighting-in-code-fences) must come after the opening tag, with any other highlighting processing instruction, e.g.:
+
+````
+```go {.myclass linenos=table,hl_lines=[8,"15-17"],linenostart=199}
+// ... code
+```
+````
+
+autoHeadingIDType ("github") {{< new-in "0.62.2" >}}
+: The strategy used for creating auto IDs (anchor names). Available types are `github`, `github-ascii` and `blackfriday`. `github` produces GitHub-compatible IDs, `github-ascii` will drop any non-Ascii characters after accent normalization, and `blackfriday` will make the IDs work as with [Blackfriday](#blackfriday), the default Markdown engine before Hugo 0.60. Note that if Goldmark is your default Markdown engine, this is also the strategy used in the [anchorize](/functions/anchorize/) template func.
+
+### Blackfriday
+
+
+[Blackfriday](https://github.com/russross/blackfriday) was Hugo's default Markdown rendering engine, now replaced with Goldmark. But you can still use it: Just set `defaultMarkdownHandler` to `blackfriday` in your top level `markup` config.
+
+This is the default config:
+
+{{< code-toggle config="markup.blackFriday" />}}
+
+### Highlight
+
+This is the default `highlight` configuration. Note that some of these settings can be set per code block, see [Syntax Highlighting](/content-management/syntax-highlighting/).
+
+{{< code-toggle config="markup.highlight" />}}
+
+For `style`, see these galleries:
+
+* [Short snippets](https://xyproto.github.io/splash/docs/all.html)
+* [Long snippets](https://xyproto.github.io/splash/docs/longer/all.html)
+
+For CSS, see [Generate Syntax Highlighter CSS](/content-management/syntax-highlighting/#generate-syntax-highlighter-css).
+
+### Table Of Contents
+
+{{< code-toggle config="markup.tableOfContents" />}}
+
+These settings only works for the Goldmark renderer:
+
+startLevel
+: The heading level, values starting at 1 (`h1`), to start render the table of contents.
+
+endLevel
+: The heading level, inclusive, to stop render the table of contents.
+
+ordered
+: Whether or not to generate an ordered list instead of an unordered list.
+
+
+## Markdown Render Hooks
+
+See [Markdown Render Hooks](/templates/render-hooks/).

+
+
+## 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).
+
+### archetypeDir

+**Default value:** false
+
+Enable to turn relative URLs into absolute.
+

+
+### 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.

+
+### enableRobotsTXT
+
+**Default value:**  false
+
+Enable generation of `robots.txt` file.

+
+{{% 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).
+
+noJSConfigInAssets {{< new-in "0.78.0" >}}
+: Turn off writing a `jsconfig.json` into your `/assets` folder with mapping of imports from running [js.Build](https://gohugo.io/hugo-pipes/js). This file is intended to help with intellisense/navigation inside code editors such as [VS Code](https://code.visualstudio.com/). Note that if you do not use `js.Build`, no file will be written.
+
+## Configure Server
+
+{{< new-in "0.67.0" >}}
+
+This is only relevant when running `hugo server`, and it allows to set HTTP headers during development, which allows you to test out your Content Security Policy and similar. The configuration format matches [Netlify's](https://docs.netlify.com/routing/headers/#syntax-for-the-netlify-configuration-file) with slightly more powerful [Glob matching](https://github.com/gobwas/glob):
+
+
+{{< code-toggle file="config">}}
+[server]
+[[server.headers]]
+for = "/**"
+
+[server.headers.values]
+X-Frame-Options = "DENY"
+X-XSS-Protection = "1; mode=block"
+X-Content-Type-Options = "nosniff"
+Referrer-Policy = "strict-origin-when-cross-origin"
+Content-Security-Policy = "script-src localhost:1313"
+{{< /code-toggle >}}
+
+Since this is is "development only", it may make sense to put it below the `development` environment:
+
+
+{{< code-toggle file="config/development/server">}}
+[[headers]]
+for = "/**"
+
+[headers.values]
+X-Frame-Options = "DENY"
+X-XSS-Protection = "1; mode=block"
+X-Content-Type-Options = "nosniff"
+Referrer-Policy = "strict-origin-when-cross-origin"
+Content-Security-Policy = "script-src localhost:1313"
+{{< /code-toggle >}}
+
+
+{{< new-in "0.72.0" >}}
+
+You can also specify simple redirects rules for the server. The syntax is again similar to Netlify's. 
+
+Note that a `status` code of 200 will trigger a [URL rewrite](https://docs.netlify.com/routing/redirects/rewrites-proxies/), which is what you want in SPA situations, e.g:
+
+{{< code-toggle file="config/development/server">}}
+[[redirects]]
+from = "/myspa/**"
+to = "/myspa/"
+status = 200
+force = false
+{{< /code-toggle >}}
+
+{{< new-in "0.76.0" >}} Setting `force=true` will make a redirect even if there is existing content in the path. Note that before Hugo 0.76  `force` was the default behaviour, but this is inline with how Netlify does it.
+
+## Configure Title Case
+
+Set `titleCaseStyle` to specify the title style used by the [title](/functions/title/) template function and the automatic section titles in Hugo. It defaults to [AP Stylebook](https://www.apstylebook.com/) for title casing, but you can also set it to `Chicago` or `Go` (every word starts with a capital letter).
+
+## Configuration Environment Variables
+
+HUGO_NUMWORKERMULTIPLIER
+: Can be set to increase or reduce the number of workers used in parallel processing in Hugo. If not set, the number of logical CPUs will be used.
+
+## Configuration Lookup Order
+
+Similar to the template [lookup order][], Hugo has a default set of rules for searching for a configuration file in the root of your website's source directory as a default behavior:
+
+1. `./config.toml`
+2. `./config.yaml`
+3. `./config.json`
+
+In your `config` file, you can direct Hugo as to how you want your website rendered, control your website's menus, and arbitrarily define site-wide parameters specific to your project.
+
+
+## Example Configuration
+
+The following is a typical example of a configuration file. The values nested under `params:` will populate the [`.Site.Params`][] variable for use in [templates][]:
+
+{{< code-toggle file="config">}}
+baseURL: "https://yoursite.example.com/"

+## Configure with Environment Variables
+
+In addition to the 3 config options already mentioned, configuration key-values can be defined through operating system environment variables.
+
+For example, the following command will effectively set a website's title on Unix-like systems:
+
+```
+$ env HUGO_TITLE="Some Title" hugo
+```
+
+This is really useful if you use a service such as Netlify to deploy your site. Look at the Hugo docs [Netlify configuration file](https://github.com/gohugoio/hugoDocs/blob/master/netlify.toml) for an example.
+
+{{% note "Setting Environment Variables" %}}
+Names must be prefixed with `HUGO_` and the configuration key must be set in uppercase when setting operating system environment variables.
+
+To set config params, prefix the name with `HUGO_PARAMS_`
+{{% /note %}}
+
+{{< new-in "0.79.0" >}} If you are using snake_cased variable names, the above will not work, so since Hugo 0.79.0 Hugo determines the delimiter to use by the first character after `HUGO`. This allows you to define environment variables on the form `HUGOxPARAMSxAPI_KEY=abcdefgh`, using any [allowed](https://stackoverflow.com/questions/2821043/allowed-characters-in-linux-environment-variable-names#:~:text=So%20names%20may%20contain%20any,not%20begin%20with%20a%20digit.) delimiter.

+## Ignore Content and Data Files when Rendering
+
+To exclude specific files from the `content` and `data` directories when rendering your site, set `ignoreFiles` to one or more regular expressions to match against the absolute file path.
+
+To ignore files ending with `.foo` or `.boo`:
+
+{{< code-toggle copy="false" >}}
+ignoreFiles = ['\.foo$', '\.boo$']
+{{< /code-toggle >}}
+
+To ignore a file using the absolute file path:
+
+{{< code-toggle copy="false" >}}
+ignoreFiles = ['^/home/user/project/content/test\.md$']
+{{< /code-toggle >}}
+
+## Configure Front Matter
+
+### Configure Dates
+
+Dates are important in Hugo, and you can configure how Hugo assigns dates to your content pages. You do this by adding a `frontmatter` section to your `config.toml`.
+
+
+The default configuration is:
+
+{{< code-toggle file="config" >}}
+[frontmatter]
+date = ["date", "publishDate", "lastmod"]
+lastmod = [":git", "lastmod", "date", "publishDate"]
+publishDate = ["publishDate", "date"]
+expiryDate = ["expiryDate"]
