-## Blackfriday Options
-
-`taskLists`
-: default: **`true`**<br>
-    Blackfriday flag: <br>
-    Purpose: `false` turns off GitHub-style automatic task/TODO list generation.
-
-`smartypants`
-: default: **`true`** <br>
-    Blackfriday flag: **`HTML_USE_SMARTYPANTS`** <br>
-    Purpose: `false` disables smart punctuation substitutions, including smart quotes, smart dashes, smart fractions, etc. If `true`, it may be fine-tuned with the `angledQuotes`, `fractions`, `smartDashes`, and `latexDashes` flags (see below).
-
-`smartypantsQuotesNBSP`
-: default: **`false`** <br>
-    Blackfriday flag: **`HTML_SMARTYPANTS_QUOTES_NBSP`** <br>
-    Purpose: `true` enables French style Guillemets with non-breaking space inside the quotes.
-
-`angledQuotes`
-: default: **`false`**<br>
-    Blackfriday flag: **`HTML_SMARTYPANTS_ANGLED_QUOTES`**<br>
-    Purpose: `true` enables smart, angled double quotes. Example: "Hugo" renders to «Hugo» instead of “Hugo”.
-
-`fractions`
-: default: **`true`**<br>
-    Blackfriday flag: **`HTML_SMARTYPANTS_FRACTIONS`** <br>
-    Purpose: <code>false</code> disables smart fractions.<br>
-    Example: `5/12` renders to <sup>5</sup>&frasl;<sub>12</sub>(<code>&lt;sup&gt;5&lt;/sup&gt;&amp;frasl;&lt;sub&gt;12&lt;/sub&gt;</code>).<br> <small><strong>Caveat:</strong> Even with <code>fractions = false</code>, Blackfriday still converts `1/2`, `1/4`, and `3/4` respectively to ½ (<code>&amp;frac12;</code>), ¼ (<code>&amp;frac14;</code>) and ¾ (<code>&amp;frac34;</code>), but only these three.</small>
-
-`smartDashes`
-: default: **`true`** <br>
-    Blackfriday flag: **`HTML_SMARTY_DASHES`** <br>
-    Purpose: `false` disables smart dashes; i.e., the conversion of multiple hyphens into an en-dash or em-dash. If `true`, its behavior can be modified with the `latexDashes` flag below.
-
-`latexDashes`
-: default: **`true`** <br>
-    Blackfriday flag: **`HTML_SMARTYPANTS_LATEX_DASHES`** <br>
-    Purpose: `false` disables LaTeX-style smart dashes and selects conventional smart dashes. Assuming `smartDashes`: <br>
-    If `true`, `--` is translated into &ndash; (`&ndash;`), whereas `---` is translated into &mdash; (`&mdash;`). <br>
-    However, *spaced* single hyphen between two words is translated into an en&nbsp;dash&mdash; e.g., "`12 June - 3 July`" becomes `12 June &ndash; 3 July` upon rendering.
-
-`hrefTargetBlank`
-: default: **`false`** <br>
-    Blackfriday flag: **`HTML_HREF_TARGET_BLANK`** <br>
-    Purpose: `true` opens <s>external links</s> **absolute** links in a new window or tab. While the `target="_blank"` attribute is typically used for external links, Blackfriday does that for _all_ absolute links ([ref](https://discourse.gohugo.io/t/internal-links-in-same-tab-external-links-in-new-tab/11048/8)). One needs to make note of this if they use absolute links throughout, for internal links too (for example, by setting `canonifyURLs` to `true` or via `absURL`).
-
-`nofollowLinks`
-: default: **`false`** <br>
-    Blackfriday flag: **`HTML_NOFOLLOW_LINKS`** <br>
-    Purpose: `true` creates <s>external links</s> **absolute** links with `nofollow` being added to their `rel` attribute. Thereby crawlers are advised to not follow the link. While the `rel="nofollow"` attribute is typically used for external links, Blackfriday does that for _all_ absolute links. One needs to make note of this if they use absolute links throughout, for internal links too (for example, by setting `canonifyURLs` to `true` or via `absURL`).
-
-`noreferrerLinks`
-: default: **`false`** <br>
-    Blackfriday flag: **`HTML_NOREFERRER_LINKS`** <br>
-    Purpose: `true` creates <s>external links</s> **absolute** links with `noreferrer` being added to their `rel` attribute. Thus when following the link no referrer information will be leaked. While the `rel="noreferrer"` attribute is typically used for external links, Blackfriday does that for _all_ absolute links. One needs to make note of this if they use absolute links throughout, for internal links too (for example, by setting `canonifyURLs` to `true` or via `absURL`).
-
-`plainIDAnchors`
-: default **`true`** <br>
-    Blackfriday flag: **`FootnoteAnchorPrefix` and `HeaderIDSuffix`** <br>
-    Purpose: `true` renders any heading and footnote IDs without the document ID. <br>
-    Example: renders `#my-heading` instead of `#my-heading:bec3ed8ba720b970`
-
-`extensions`
-: default: **`[]`** <br>
-    Purpose: Enable one or more Blackfriday's Markdown extensions (**`EXTENSION_*`**). <br>
-    Example: Include `hardLineBreak` in the list to enable Blackfriday's `EXTENSION_HARD_LINE_BREAK`. <br>
-    *See [Blackfriday extensions](#blackfriday-extensions) section for information on all extensions.*
-
-`extensionsmask`
-: default: **`[]`** <br>
-    Purpose: Disable one or more of Blackfriday's Markdown extensions (**`EXTENSION_*`**). <br>
-    Example: Include `autoHeaderIds` as `false` in the list to disable Blackfriday's `EXTENSION_AUTO_HEADER_IDS`. <br>
-    *See [Blackfriday extensions](#blackfriday-extensions) section for information on all extensions.*
-
-`skipHTML`
-: default: **`false`** <br>
-    Blackfriday flag: **`HTML_SKIP_HTML`** <br>
-    Purpose: `true` causes any HTML in the markdown files to be skipped.
-
-## Blackfriday extensions
-
-`noIntraEmphasis`
-: default: *enabled* <br>
-    Purpose: The "\_" character is commonly used inside words when discussing
-    code, so having Markdown interpret it as an emphasis command is usually the
-    wrong thing.  When enabled, Blackfriday lets you treat all emphasis markers
-    as normal characters when they occur inside a word.
-
-`tables`
-: default: *enabled* <br>
-    Purpose: When enabled, tables can be created by drawing them in the input
-    using the below syntax:
-    Example:
-
-           Name | Age
-        --------|------
-            Bob | 27
-          Alice | 23
-
-`fencedCode`
-: default: *enabled* <br>
-    Purpose: When enabled, in addition to the normal 4-space indentation to mark
-    code blocks, you can explicitly mark them and supply a language (to make
-    syntax highlighting simple).
-
-    You can use 3 or more backticks to mark the beginning of the block, and the
-    same number to mark the end of the block.
-
-    Example:
-
-         ```md
-        # Heading Level 1
-        Some test
-        ## Heading Level 2
-        Some more test
-        ```
-
-`autolink`
-: default: *enabled* <br>
-    Purpose: When enabled, URLs that have not been explicitly marked as links
-    will be converted into links.
-
-`strikethrough`
-: default: *enabled* <br>
-    Purpose: When enabled, text wrapped with two tildes will be crossed out. <br>
-    Example: `~~crossed-out~~`
-
-`laxHtmlBlocks`
-: default: *disabled* <br>
-    Purpose: When enabled, loosen up HTML block parsing rules.
-
-`spaceHeaders`
-: default: *enabled* <br>
-    Purpose: When enabled, be strict about prefix header rules.
-
-`hardLineBreak`
-: default: *disabled* <br>
-    Purpose: When enabled, newlines in the input translate into line breaks in
-    the output.
-
-
-`tabSizeEight`
-: default: *disabled* <br>
-    Purpose: When enabled, expand tabs to eight spaces instead of four.
-
-`footnotes`
-: default: *enabled* <br>
-    Purpose: When enabled, Pandoc-style footnotes will be supported.  The
-    footnote marker in the text that will become a superscript text; the
-    footnote definition will be placed in a list of footnotes at the end of the
-    document. <br>
-    Example:
-
-        This is a footnote.[^1]
-
-        [^1]: the footnote text.
-
-`noEmptyLineBeforeBlock`
-: default: *disabled* <br>
-    Purpose: When enabled, no need to insert an empty line to start a (code,
-    quote, ordered list, unordered list) block.
-
-
-`headerIds`
-: default: *enabled* <br>
-    Purpose: When enabled, allow specifying header IDs with `{#id}`.
-
-`titleblock`
-: default: *disabled* <br>
-    Purpose: When enabled, support [Pandoc-style title blocks][1].
-
-`autoHeaderIds`
-: default: *enabled* <br>
-    Purpose: When enabled, auto-create the header ID's from the headline text.
-
-`backslashLineBreak`
-: default: *enabled* <br>
-    Purpose: When enabled, translate trailing backslashes into line breaks.
-
-`definitionLists`
-: default: *enabled* <br>
-    Purpose: When enabled, a simple definition list is made of a single-line
-    term followed by a colon and the definition for that term. <br>
-    Example:
-
-        Cat
-        : Fluffy animal everyone likes
-
-        Internet
-        : Vector of transmission for pictures of cats
-
-    Terms must be separated from the previous definition by a blank line.
-
-`joinLines`
-: default: *enabled* <br>
-    Purpose: When enabled, delete newlines and join the lines.
