+
+## HEAD
+
+{: .note }
+This website is built from the `HEAD` of the `main` branch of the theme repository.
+
+{: .warning }
+This website includes docs for some new features that are not available in `v0.4.0.rc5` and `v0.3.3`!
+
+Changes to `main` that are *not* in the latest pre-release:
+
+- n/a
+
+## Pre-release v0.4.0.rc5
+
+Hi everyone, we're so excited to finally release `v0.4.0`! For posterity's sake, we're going to release `v0.4.0.rc5` and then immediately re-release it as `v0.4.0`; this should make it more clear what changes were introduced in the lead up to the minor release.
+
+This RC does not introduce any major user-facing features. It adds more customizability for custom SCSS variables (fixing a bug with callout introduction order), `lunr` indexing, and loading `mermaid` locally. In addition, it fixes bugs introduced in `.rc4`: incorrect CSS, inconsistencies with code block backgrounds in dark theme, and the copy code button. It also adds a migration guide for users coming from `v0.3.3`.
+
+### Trying out pre-release `v0.4.0.rc5`
+
+Simlar to the prior release, `v0.4.0.rc5` is a **release candidate** for the theme (i.e., a pre-release) with release `v0.4.0` following immediately after. While we don't anticipate many users using this RC, it is still possible to opt-in.
+
+To use this RC explicitly as a remote theme:
+
+```yml
+remote_theme: just-the-docs/just-the-docs@v0.4.0.rc5
+```
+
+To use this RC explicitly as a gem-based theme, pin the version in your `Gemfile` and re-run `bundle install` or `bundle update just-the-docs`:
+
+```Ruby
+gem "just-the-docs", "0.4.0.rc5"
+```
+
+By default, **users will not be upgraded to `0.4.0.rc5`**. To enforce that explicitly, either:
+
+1. pin your gem version in your `Gemfile`, like so
+```Ruby
+gem "just-the-docs", "0.3.3"
+```
+2. freeze the `remote_theme`, like so
+```yml
+remote_theme: just-the-docs/just-the-docs@v0.3.3
+```

+## Pre-release v0.4.0.rc4
+
+Happy new year! We're celebrating with another pre-release, with features that should help theme users better adapt to changes moving forward. **We aim to re-release this as `v0.4.0`, with only few changes**.
+
+Notable new additions include:
+
+- modular site components, which split up the site into smaller reusable components; advanced theme users can then remix layouts quickly without duplication
+- a "copy code" button to code blocks
+- fixing bugs in generated TOCs and navigation from previous prereleases
+- various cleanups of CSS and HTML markup
+
+The roadmap to `v0.4.0` is small. We are only looking to:
+
+- finish a migration guide, so users can easily upgrade from `v0.3.3` to `v0.4.0`
+- fix one last bug relating to callouts and custom colors
+- fix any new bugs introduced by this pre-release
+
+Have any questions, thoughts, or concerns? We'd love to hear from you! Please [open an issue](https://github.com/just-the-docs/just-the-docs/issues) or [start a discussion](https://github.com/just-the-docs/just-the-docs/discussions) and let us know!
+
+### Trying out pre-release `v0.4.0.rc4`
+
+Simlar to the prior release, `v0.4.0.rc4` is a **release candidate** for the theme (i.e., a pre-release) with release `v0.4.0` coming soon. We want your help in testing the changes! As of now, the gem on RubyGems and the repository are updated to `v0.4.0.rc4`.
+
+To use this RC explicitly as a remote theme:
+
+```yml
+remote_theme: just-the-docs/just-the-docs@v0.4.0.rc4
+```
+
+To use this RC explicitly as a gem-based theme, pin the version in your `Gemfile` and re-run `bundle install` or `bundle update just-the-docs`:
+
+```Ruby
+gem "just-the-docs", "0.4.0.rc4"
+```
+
+By default, **users will not be upgraded to `0.4.0.rc4`**. To enforce that explicitly, either:
+
+1. pin your gem version in your `Gemfile`, like so
+```Ruby
+gem "just-the-docs", "0.3.3"
+```
+2. freeze the `remote_theme`, like so
+```yml
+remote_theme: just-the-docs/just-the-docs@v0.3.3
+```

+## Pre-release v0.4.0.rc3
+
+Hi there! This is (actually) hopefully the last prerelease before `v0.4.0`; in particular, if we find that this prerelease is stable, we'll re-release it as `v0.4.0`.
+
+In general, this is a more mature pre-release; there are few new features. However, we'll highlight [@pdmosses]'s work in [#992] to better optimize nav generation for large sites (ex 100+ pages). We don't expect this to affect most users; however, **it is technically a breaking change**, and we suggest testing your site before upgrading to this prerelease.
+
+We want your feedback! Please [open an issue](https://github.com/just-the-docs/just-the-docs/issues) or [start a discussion](https://github.com/just-the-docs/just-the-docs/discussions) and let us know!
+
+As soon as we get stable test results from major downstream users, we'll push out a `v0.4.0` ASAP - closing out almost 2 years of backlogged work!
+
+### Trying out pre-release `v0.4.0.rc3`

+## Pre-release v0.4.0.rc2
+
+{: .warning }
+This website includes docs for some new features that are not available in `v0.4.0.rc1` and `v0.3.3`!
+
+Hey there! This is likely the last pre-release before releasing `v0.4.0`, which we plan on doing soon (i.e. before the end of the month) - very exciting! Some new additions to highlight:
+
+- significant improvement on build time of navigation panel by [@pdmosses]
+  - this is big: for a community member with over 300 pages, we shortened the build time from 3 minutes to 30 seconds!
+- improved accessibility features led by [@JPrevost]
+- more docs!
+
+The intention of this release candidate is to gather even more feedback on a potential `v0.4.0`. As it stands, we have not encountered any breaking changes with early adopters of `v0.4.0.rc1`. If you encounter any - for either of our pre-releases - please let us know!

+## Pre-release v0.4.0.rc1
+
+### We're back!
+
+Hi all! The Just the Docs team is excited to have our first pre-release in over two years! It is jam-packed with features and bugfixes that have been requested by the community since 2020. They include:
+
+- The new callouts component
+- Allowing pages and collections to coexist on the navigation pane
+- New styling: dark syntax highlighting, support for jekyll-asciidoc, word-wrapping instead of overflow for various elements
+- More customization: external nav links, custom nav footers, favicon includes, search color and placeholder configuration, mermaid.js support, and nav sorting
+- Over 20 bugfixes! Big ones include fixing the `rake` command, using `relative_url`, and search input color
+- More documentation, especially on using custom includes
+- Updating core dependencies to stable Ruby versions
+- A WIP [template repository](https://github.com/just-the-docs/just-the-docs-template) that allows you to setup your own repository using Just the Docs and GitHub Pages with one click - give it a shot! More documentation, etc. is on the way!
+
+We want your feedback! Are these changes helpful? Are our docs easy to understand? Should new features like `mermaid` be opt-in or opt-out? Please [open an issue](https://github.com/just-the-docs/just-the-docs/issues) or [start a discussion](https://github.com/just-the-docs/just-the-docs/discussions) and let us know!
+
+### Trying out pre-release `v0.4.0.rc1`
+
+Due to the massive scope of these changes, we're making `v0.4.0.rc1` avaialble as a **release candidate** for the theme (i.e., a pre-release) with release `v0.4.0` coming soon. We want your help in testing the changes! As of now, the gem on RubyGems and the repository are updated to `v0.4.0.rc1`.
+
+To use this RC explicitly as a remote theme:
+
+```yml
+remote_theme: just-the-docs/just-the-docs@v0.4.0.rc1
+```
+
+To use this RC explicitly as a gem-based theme, pin the version in your `Gemfile` and re-run `bundle install` or `bundle update just-the-docs`:
+
+```Ruby
+gem "just-the-docs", "0.4.0.rc1"
+```
+
+### Staying on `v0.3.3`
+
+If you're not ready to make the switch, that's alright! If your version of just-the-docs is pinned to `v0.3.3` (i.e. by a `Gemfile.lock` or in `remote_theme`, then there's nothing you need to do.
+
+If you have not pinned your theme version, you should either:
+
+1. pin your gem version in your `Gemfile`, like so
+```Ruby
+gem "just-the-docs", "0.3.3"
+```
+2. freeze the `remote_theme`, like so
+```yml
+remote_theme: just-the-docs/just-the-docs@v0.3.3
+```
+
+{: .warning }
+Use of branches for closed PRs (e.g., [#466], [#578]) is now deprecated, as those branches have been (directly or indirectly) merged, and they may be deleted after the pre-release of `v0.4.0.rc1`.
+
+### Maintenance
+
+Internally, our maintainer team has expanded: [Patrick Marsceill][@pmarsceill], the original maintainer, has stepped down from an active role after almost 4 years! We're very thankful for the work that he's done to create and maintain one of the most popular Jekyll themes. Please join us in giving him thanks!
+
+The new core team currently consists of [@mattxwang], [@pdmosses], [@skullface], [@dougaitken], and [@max06]. Over the past six months, we've been triaging and merging in PRs, as well as contributing our own fixes. We'll continue to address open issues, merge in PRs from the community, and plan out the future of Just the Docs. If you'd like to contribute, now is a great time!

+
+### Roadmap
+
+In the short-term, we're committed to tidying up everything for a `v0.4.0` release. This involves fixing bugs reported from the community in this pre-release, as well as continually merging in minor PRs.
+
+We're also scoping out medium and long-term projects, and want to keep you in the loop. These include:
+
+- upgrading to Jekyll 4, and stopping support for Jekyll 3
+- versioned docs - issue [#728]
+- improved accessibility - issues [#566], [#870]
+- internationalization (i18n) - issue [#59]
+- recursive/multi-level navigation - PR [#462]
+- toggleable dark mode - issue [#234]
+
+as well as DX improvements like better regression tests, CI, and tooling. If you're interested in any of these, please join us [on GitHub](https://github.com/just-the-docs/just-the-docs) - any contribution (raising an issue, writing docs, or submitting a PR) is welcome!

+# Migrating and Upgrading
+
+Summary
+:   A site that uses `just-the-docs` (as a theme or as a remote them) automatically
+    switches to a new release, unless it is pinned to a previous version.
+
+    This migration guide draws attention to:
+
+    - changes that might break your site,
+    - features added in the latest release, and
+    - features that have become deprecated (and are likely to be removed in a future release).
+
+This document contains instructions on how to migrate and upgrade Just the Docs sites from every minor or major version bump, starting from `v0.3.3` to `v0.4.0`.
+

+> If your configuration states `theme: just the docs` and your `Gemfile` specifies

+## v0.3.3 … v0.4.x
+
+### REPOSITORY CHANGES
+
+#### Just the Docs
+
+The theme repo is now at <https://github.com/just-the-docs/just-the-docs>.
+The name of its default branch is now `main`.
+
+The theme docs website is now published at <https://just-the-docs.github.io/just-the-docs>.
+
+GitHub provides access to previous versions of the theme repo.
+You can browse [previous versions of the theme docs website] on the [Internet Archive].
+
+[previous versions of the theme docs website]: https://web.archive.org/web/20220000000000*/https://just-the-docs.github.io/just-the-docs
+[Internet Archive]: https://web.archive.org/
+
+The [README] page on the theme repo repeats much of the information from the [home page],
+formatted for browsing on GitHub.
+It also explains how to install the theme as a Ruby Gem, without creating a new site.
+
+[README]: https://github.com/just-the-docs/just-the-docs/blob/main/README.md
+[home page]: https://just-the-docs.github.io/just-the-docs
+
+#### Deploy previews
+
+When a PR builds successfully, Netlify provides a preview of how the theme docs website will look if the PR is merged.
+You can find links to the preview near the bottom of the Conversation tab of the PR.
+
+#### Just the Docs Template
+
+The template at <https://github.com/just-the-docs/just-the-docs-template>
+creates a repo with the minimal source files for a Just the Docs website.
+After configuring the relevant parameters, you can build and serve the website
+both locally and on GitHub Pages – using either Jekyll 3 or Jekyll 4!
+
+#### Just the Docs Tests
+
+The tests website at <https://just-the-docs.github.io/just-the-docs-tests>
+consists mainly of regression tests for bug fixes and new features.
+
+The test source files at <https://github.com/just-the-docs/just-the-docs-tests>
+illustrate the use of many Markdown and Jekyll features,
+including some that are not included in the theme docs.
+
+For example, see how to add support for rendering TeX/LaTeX [math formulas] with KaTeX and MathJax.
+
+[math formulas]: https://just-the-docs.github.io/just-the-docs-tests/components/math/index/
+
+### POTENTIALLY-BREAKING CHANGES in v0.4.0
+
+If switching to a new release of the theme breaks your website,
+check that you don't have any files in the `_includes`, `_layouts`, and `_sass`
+directories with the same names as files provided by the theme.
+
+If your repo has a customised copy of `_layouts/default.html` from a previous release,
+try removing it, or replace it by a fresh copy of the theme file.
+
+{: .warning }
+The following changes made in v0.4.0 *might* break or adversely affect your website
+when you next rebuild it, unless you have pinned it!
+
+#### New includes and SCSS
+
+Version 0.4.0 introduces many new `_includes` files. If you already have an existing include with the same name as a new addition, you will need to migrate or update that include. The new files are (relative to the `_includes` folder):
+
+- `mermaid_config.js`
+- `nav_footer_custom`
+- `search_placeholder_custom`
+- `toc_heading_custom`
+- the entire `components/` folder:
+  - `aux_nav`, `breadcrumbs`, `children_nav`, `footer`, `header`, `mermaid`, `search_footer`, `search_header`, `sidebar`
+- the entire `icons/` folder
+  - `code_copy`, `document`, `expand`, `external_link`, `icons`, `link`, `menu`, `search`
+- the entire `lunr/` folder
+  - `custom-data.json`, `custom-index.js`
+
+We have removed some code in `_sass/vendor` and added a new file at `_sass/custom/setup.scss`.
+
+#### favicons
+
+The file `_includes/favicon.html` is now ignored by the theme.
+If you're using it, your website's favicon is no longer displayed by browsers.
+
+To fix: Move the content of `_includes/favicon.html` to `_includes/head_custom.html`.
+
+#### Custom callout colors
+
+The file `_sass/custom/custom.scss` is now imported last: _after_ the configuration of callouts.
+If you've defined custom color variables for callouts in `_sass/custom/custom.scss`
+(and used them when configuring your callouts in `_config.yml`)
+you will not be able to rebuild your website.
+
+To fix: Move custom color variables for callouts in `_sass/custom/custom.scss` to `_sass/custom/variables.scss`.
+
+#### Pages and collections
+
+Links to ordinary pages now appear in the navigation on sites that use collections.
+You might want the navigation of your site to consist entirely of collections.
+
+To fix: Add the front matter `nav_exclude: true` to pages that the navigation should not display.
+
+#### Relative URLs
+
+All generated URLs are now relative.
+This is a bug fix, and unlikely to break any site.
+
+Relative links to pages within a website support deployment to different servers.
+
+#### Navigation order
+
+The order in which the navigation panel lists pages has been simplified.
+All pages with `nav_order` values now come before all pages that are ordered by `title`.
+
+If your website has a group of *sibling* pages where some siblings have `nav_order`
+string values, and others are ordered by numerical `title` values,
+the former now come before the latter.
+
+To fix: Add numerical `nav_order` values to the pages with numerical `title` values.
+
+### DEPRECATIONS
+
+{: .warning }
+The following features are deprecated, and to be removed in a future release.
+
+#### Jekyll 3
+
+You can still use Jekyll 3 (3.8.5 or later) to build websites using v0.4.0 of the theme.
+However, future releases of the theme may require the use of Jekyll 4.
+
+You can already use Jekyll 4 to build your website *locally*.
+It should look exactly the same as when built with Jekyll 3.[^Jekyll4]
+
+[^Jekyll4]:
+    Jekyll 4 depends on more recent versions of other gems than Jekyll 3,
+    and the differences between those versions may affect the files of your built site.
+
+To use Jekyll 4 when building your website *on GitHub Pages*, you need to run GitHub Actions.
+The simplest way of setting that up in a new repo is to create the repo using the Just the Docs template.
+To start running Jekyll 4 to build an existing repo on GitHub Pages,
+you can create a new repo with the template, then copy its `.github/workflows` directory,
+and update your repo settings to use Actions.
+
+#### Footer content configuration
+
+Currently, if your configuration sets `footer_content` to some text,
+the theme displays that text at the bottom of the main section of each page.
+
+The file `_includes/footer_custom.html` provides a more general way of customizing
+not only the text but also the markup for the page footer area.
+
+You can replicate the current display of `TEXT` in the footer using the following markup:
+
+```html
+<p class="text-small text-grey-dk-100 mb-0">TEXT</p>
+```
+
+### THEME WEBSITE CHANGES
+
+The website now uses *callouts*[^callouts] to draw attention to important information.
+
+[^callouts]:
+    The theme website configuration defines the callout titles and colors used there.
+    Websites that use the theme have to configure their own callout titles and colors.
+
+The theme uses [semantic versioning].
+A normal version number takes the form X.Y.Z,
+where X is the major version, Y is the minor version, and Z is the patch version.
+The theme uses version X.Y.Z.rcN for pre-release N of version X.Y.Z.
+When referring to version numbers on GitHub, we usually prefix them by 'v'.
+
+[semantic versioning]: https://semver.org
+
+Major version zero (0.Y.Z) is for initial development, where anything *may* change at any time.
+In practice, we increment the patch version Z for bug fixes and backwards compatible changes;
+we increment the minor version Y for changes that could break websites using the theme
+without pinning it to a specific version.
+
+The label `NEW` in the theme website indicates a feature that has been changed or added
+since the release of the previous *minor* version.
+For example, after the release of v0.4.Z, the theme website should label `NEW` all features that
+we have changed or added since v0.3.0 – not just since v0.3.3.
+When we release v0.5.0, we will remove all those labels, and add labels on features since v0.4.0.
+
+The theme docs website is not itself versioned.
+It changes incrementally, independently of theme releases.
+
+#### Home page
+
+The theme home page now focuses on the simplest ways of using the theme.
+It also notes the different behaviour of `theme` and `remote_theme` in connection
+with interim versions of the theme, such as pre-releases.
+
+#### CHANGELOG
+
+The CHANGELOG page lists the changes made in all previous releases and pre-releases of new versions of the theme gem.
+
+It also lists changes made to the `main` branch of the theme since the latest release or pre-release.
+
+For changes since v0.3.3, the log usually references the merged PR that made the change and its author.
+
+### NON-BREAKING CHANGES (OUTLINE ONLY)
+
+Brief descriptions of the following changes are to be added below.
+
+#### Accessibility
+
+- Skip to main content: the first keyboard-navigatable item is now a link to skip over the sidebar and header to the main content of the page. PR: [#949].
+- Aria-labels: improved `aria-label`s have been added to various site elements. PRs: [#950], ...
+- Other general improvements: gradual changes have improved tab focusability, contrast, and semantic elements. More work still to come. PRs: [#498], [#846]
+
+#### Configuration
+
+- Mermaid support: first-class support for [Mermaid](https://mermaid.js.org/) - a JavaScript-based diagram and charting tool supported by GitHub - has been added to the theme. **This feature is opt-in.** See the new doc subsections in [Configuration]({% link docs/configuration.md %}#mermaid-diagrams) and [Code]({% link docs/ui-components/code.md %}#mermaid-diagram-code-blocks) for more.
+- Multiple Google Analytics tags are now supported. PR: [#1029]
+
+#### Customization
+
+- all user-facing text is now customizable; previously, several elements (ex search placeholder) were hardwired into the theme. Now, users can blend custom includes and layouts to internationalize their sites.
+- we've clarified the role of `custom.scss` to be imported last; to allow users to define custom or override variables, we've added a new file `setup.scss`. PR: [#1135]
+
+#### Custom Includes
+
+We've added several custom `_includes` to provide users with more customization options for different site elements. We've also added a section to [Configuration]({% link docs/customization.md %}#override-includes) to outline these.
+
+All of these are opt-in by default; however, **these may be breaking if you have existing `_includes` with the same name**.
+
+Each item is listed with the relevant file and PR.
+
+- TOC heading: `toc_heading_custom.html`, PR: [#980]
+- Navigation panel footer: `nav_footer_custom.html`, PR: [#474]
+- Search placeholder: `search_placeholder_custom.html`, PR: [#613]
+- Modular site components: `components/` and `icons/`, PR: [#1058]
+- Custom search indices: `lunr/`, PR: [#1068]
+
+In a future (version 1) release, we may rename the custom include files.
+
+#### Modular Components
+
+We've broken up the default layout (`_layouts/default.html`) into multiple reusable components. This should have no impact on most users; however, it should make it easier to implement custom layouts.
+
+For more, see [Custom layouts and includes]({% link docs/customization.md %}#custom-layouts-and-includes). PR: [#1058].
+
+#### Navigation
+
+- Collections: nav panel shows links to ordinary pages before collections
+- Collection folding; part of "Combination". PR: [#578]
+- Scrolling to show link to selected page. PR: [#639]
+- External nav links are now supported. PR: [#876]
+- Child nav order: sort navigation pages with `child_nav_order`. PR: [#726]
+- Order when mixing different ways of specifying nav order
+
+#### Search
+
+In addition to customizing the search placeholder, we've also added the ability to provide custom content to the search index. for more, see [Custom content for search index]({% link docs/search.md %}#custom-content-for-search-index). PR: [#1068].
+
+#### Styling
+
+- Code copying: code blocks now allow users to easily copy their contents. PR: [#945]
+- Blockquote: shows vertical bar on left. PR: [#965]
+- Links wrap. PR: [#905]
+- Callouts: a new component similar to alerts or banners. See [UI Components - Callouts]({% link docs/ui-components/callouts.md %}). PR: [#466]

 ## Installation
 
-Add this line to your Jekyll site's Gemfile:
+### Use the template
+
+The [Just the Docs Template] provides the simplest, quickest, and easiest way to create a new website that uses the Just the Docs theme. To get started with creating a site, just click "[use the template]"!
+
+Note: To use the theme, you do ***not*** need to clone or fork the [Just the Docs repo]! You should do that only if you intend to browse the theme docs locally, contribute to the development of the theme, or develop a new theme based on Just the Docs.
+
+You can easily set the site created by the template to be published on [GitHub Pages] – the [template README] file explains how to do that, along with other details.
+
+If [Jekyll] is installed on your computer, you can also build and preview the created site *locally*. This lets you test changes before committing them, and avoids waiting for GitHub Pages.[^2] And you will be able to deploy your local build to a different platform than GitHub Pages.
+
+More specifically, the created site:
+
+- uses a gem-based approach, i.e. uses a `Gemfile` and loads the `just-the-docs` gem
+- uses the [GitHub Pages / Actions workflow] to build and publish the site on GitHub Pages
+
+Other than that, you're free to customize sites that you create with the template, however you like. You can easily change the versions of `just-the-docs` and Jekyll it uses, as well as adding further plugins.
+
+### Use RubyGems
+
+Alternatively, you can install the theme as a Ruby Gem, without creating a new site.
+
+Add this line to your Jekyll site's `Gemfile`:
 
 ```ruby
 gem "just-the-docs"

+To set up your environment to develop this theme: fork this repo, the run `bundle install` from the root directory.
+
+A modern [devcontainer configuration](https://code.visualstudio.com/docs/remote/containers) for VSCode is included.
 
 Your theme is set up just like a normal Jekyll site! To test your theme, run `bundle exec jekyll serve` and open your browser at `http://localhost:4000`. This starts a Jekyll server using your theme. Add pages, documents, data, etc. like normal to test your theme's contents. As you make modifications to your theme and to your content, your site will regenerate and you should see the changes in the browser after a refresh, just like normal.
 
-When the theme is released, only the files in `_layouts`, `_includes`, and `_sass` tracked with Git will be released.

+{%- comment -%}
+This file can be used to fix the HTML produced by Jekyll for highlighted
+code with line numbers.
+
+It works with `{% highlight some_language linenos %}...{% endhighlight %}`
+and with the Kramdown option to add line numbers to fenced code.
+
+The implementation was derived from the workaround provided by 
+Dmitry Hrabrov (DeXP) at
+https://github.com/penibelst/jekyll-compress-html/issues/71#issuecomment-188144901
+
+EXPLANATION
+
+The HTML produced by Rouge highlighting with lie numbers is of the form
+`code table`. Jekyll (<= 4.1.1) always wraps the highlighted HTML
+with `pre`. This wrapping is not only unnecessary, but also transforms
+the conforming HTML produced by Rouge to non-conforming HTML, which
+results in HTML validation error reports. 
+
+The fix removes the outer `pre` tags whenever they contain the pattern
+`<table class="rouge-table">`.
+  
+Apart from avoiding HTML validation errors, the fix allows the use of
+the [Jekyll layout for compressing HTML](http://jch.penibelst.de),
+which relies on `pre` tags not being nested, according to
+https://github.com/penibelst/jekyll-compress-html/issues/71#issuecomment-172069842 
+
+USAGE
+
+(Any names can be used for `some_var` and `some_language`.)
+
+{% capture some_var %}
+{% highlight some_language linenos %}
+Some code
+{% endhighlight %}
+{% endcapture %}
+{% include fix_linenos.html code=some_var %}
+
+For code fences:
+
+{% capture some_var %}
+```some_language
+Some code
+```
+{% endcapture %}
+{% assign some_var = some_var | markdownify %}
+{% include fix_linenos.html code=some_var %}
+
+CAVEATS
+
+The above does not work when `Some code` happens to contain the matched string 
+`<table class="rouge-table">`.
+
+The use of this file overwrites the variable `fix_linenos_code` with `nil`.
+
+{%- endcomment -%}
+
+{% assign fix_linenos_code = include.code %}
+{% if fix_linenos_code contains '<table class="rouge-table">' %}
+  {% assign fix_linenos_code = fix_linenos_code | replace: '<pre class="highlight">', '<pre>' %}

+  The order of sibling pages in `pages_list` determines the order of display of
+  links to them in lists of navigation links and in auto-generated TOCs.
+  
+  Note that Liquid evaluates conditions from right to left (and it does not allow
+  the use of parentheses). Some conditions are not so easy to express clearly...
+  
+  For example, consider the following condition:
+  
+    C: page.collection = = include.key and 
+       page.url = = node.url or 
+       page.grand_parent = = node.title or 
+       page.parent = = node.title and 
+       page.grand_parent = = nil
+ 
+  Here, `node` is a first-level page. The last part of the condition
+  -- namely: `page.parent = = node.title and page.grand_parent = = nil` --
+  is evaluated first; it holds if and only if `page` is a child of `node`.
+  
+  The condition `page.grand_parent = = node.title or ...` holds when 
+  `page` is a grandchild of node, OR `...` holds.
+  
+  The condition `page.url = = node.url or ...` holds when 
+  `page` is `node`, OR `...` holds.
+  
+  The condition C: `page.collection = = include.key and ...` holds when we are 
+  generating the nav links for a collection that includes `page`, AND `...` holds.

+
+    Parameters:
+      * html          (string) - the HTML of compiled markdown generated by kramdown in Jekyll
+
+    Optional Parameters:
+      * beforeHeading (bool)   : false  - Set to true if the anchor should be placed _before_ the heading's content
+      * headerAttrs   (string) :  ''    - Any custom HTML attributes that will be added to the heading tag; you may NOT use `id`;
+                                          the `%heading%` and `%html_id%` placeholders are available
+      * anchorAttrs   (string) :  ''    - Any custom HTML attributes that will be added to the `<a>` tag; you may NOT use `href`, `class` or `title`;
+                                          the `%heading%` and `%html_id%` placeholders are available
+      * anchorBody    (string) :  ''    - The content that will be placed inside the anchor; the `%heading%` placeholder is available
+      * anchorClass   (string) :  ''    - The class(es) that will be used for each anchor. Separate multiple classes with a space
+      * anchorTitle   (string) :  ''    - The `title` attribute that will be used for anchors
+      * h_min         (int)    :  1     - The minimum header level to build an anchor for; any header lower than this value will be ignored
+      * h_max         (int)    :  6     - The maximum header level to build an anchor for; any header greater than this value will be ignored
+      * bodyPrefix    (string) :  ''    - Anything that should be inserted inside of the heading tag _before_ its anchor and content
+      * bodySuffix    (string) :  ''    - Anything that should be inserted inside of the heading tag _after_ its anchor and content
+      * generateId    (true)   :  false - Set to true if a header without id should generate an id to use.
+
+    Output:
+      The original HTML with the addition of anchors inside of all of the h1-h6 headings.

+# OneDarkJekyll
+
+*Use Atom's One Dark syntax colors in your Jekyll powered blog!*
+
+It's LESS file which can be compiled to a - Pygments, Rouge compatible - stylesheet from Atom editor's One Dark syntax theme (and any theme based on it, for example One Dark Vivid, Firewatch, etc.).
+
+Download the stylesheet files or compile a new one from any Atom syntax theme which based on One Dark (the variable names in `colors.less` must match with One Dark's)
+
+## Create a new syntax stylesheet
+
+1. `npm install -g less less-plugin-clean-css`
+2. Clone this repository
+3. Download the `colors.css` file from the syntax theme's repository (for example https://github.com/atom/one-dark-syntax/blob/master/styles/colors.less in case of One-Dark)
+4. Put the previously downloaded file next to `syntax.less`
+5. Run `lessc syntax.less syntax.css --clean-css`
+6. Use the `syntax.css`
+
+It's not final and in case you find any error/improvement feel free to create a PR. :)
+
+----
+
+# UPDATES FOR USE IN JUST-THE-DOCS:
+
+1. Layout added in `*.css`
+2. Renamed `*.css` to `*.scss`
