+{%- 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 %}

+    The values of `title` and `nav_order` can be numbers or strings.
+    Jekyll gives build failures when sorting on mixtures of different types,
+    so numbers and strings need to be sorted separately.
+
+    Here, numbers are sorted by their values, and come before all strings.
+    An omitted `nav_order` value is equivalent to the page's `title` value
+    (except that a numerical `title` value is treated as a string).
+
+    The case-sensitivity of string sorting is determined by `site.nav_sort`.

-
-No other styles should come before Normalize.scss.
-
-It's recommendable to modify `normalize.scss` to suit it to your project
-
-## What does it do?
-
-* Preserves useful defaults, unlike many CSS resets.
-* Normalizes styles for a wide range of elements.
-* Corrects bugs and common browser inconsistencies.
-* Improves usability with subtle improvements.
-* Explains what code does using detailed comments.
-
-## Browser support
-
-* Google Chrome (latest)
-* Mozilla Firefox (latest)
-* Mozilla Firefox 4
-* Opera (latest)
-* Apple Safari 6+
-* Internet Explorer 8+
-
-[Normalize.css v1 provides legacy browser
-support](https://github.com/necolas/normalize.css/tree/v1) (IE 6+, Safari 4+),
-but is no longer actively developed.
-
-## Extended details
-
-Additional detail and explanation of the esoteric parts of normalize.css.
-
-#### `pre, code, kbd, samp`
-
-The `font-family: monospace, monospace` hack fixes the inheritance and scaling
-of font-size for preformated text. The duplication of `monospace` is
-intentional.  [Source](http://en.wikipedia.org/wiki/User:Davidgothberg/Test59).
-
-#### `sub, sup`
-
-Normally, using `sub` or `sup` affects the line-box height of text in all
-browsers. [Source](http://gist.github.com/413930).
-
-#### `svg:not(:root)`
-
-Adding `overflow: hidden` fixes IE9's SVG rendering. Earlier versions of IE
-don't support SVG, so we can safely use the `:not()` and `:root` selectors that
-modern browsers use in the default UA stylesheets to apply this style. [SVG
-Mailing List discussion](http://lists.w3.org/Archives/Public/public-svg-wg/2008JulSep/0339.html)
-
-#### `input[type="search"]`
-
-The search input is not fully stylable by default. In Chrome and Safari on
-OSX/iOS you can't control `font`, `padding`, `border`, or `background`. In
-Chrome and Safari on Windows you can't control `border` properly. It will apply
-`border-width` but will only show a border color (which cannot be controlled)
-for the outer 1px of that border. Applying `-webkit-appearance: textfield`
-addresses these issues without removing the benefits of search inputs (e.g.
-showing past searches).
-
-#### `legend`
-
-Adding `border: 0` corrects an IE 8–11 bug where `color` (yes, `color`) is not
-inherited by `legend`.

+By default, the navigation and search include normal [pages](https://jekyllrb.com/docs/pages/).
+Instead, you can also use [Jekyll collections](https://jekyllrb.com/docs/collections/) which group documents semantically together.
+
+For example, put all your documentation files in the `_docs` folder and create the `docs` collection:
+```yaml
+# Define Jekyll collections
+collections:
+  # Define a collection named "docs", its documents reside in the "_docs" directory
+  docs:
+    permalink: "/:collection/:path/"
+    output: true

+      # Exclude the collection from the search
+      # Supports true or false (default)

+
+You can reference multiple collections.

 To allow search for hyphenated words:
 
 ```yaml
 # Set the search token separator
-search_tokenizer_separator: /[\s/]+/
+# Default: /[\s\-/]+/
+# Example: enable support for hyphenated search words
+search.tokenizer_separator: /[\s/]+/

-Sometimes you might have a page that you don't want to be indexed for the search nor to show up in search results, e.g, a 404 page. To exclude a page from search, add the `search_exclude: true` parameter to the page's YAML front matter:

+## Generate search index when used as a gem
+
+If you use Just the Docs as a remote theme, you do not need the following steps.
+
+If you use the theme as a gem, you must initialize the search by running this `rake` command that comes with `just-the-docs`:
+
+```bash
+$ bundle exec just-the-docs rake search:init
+```
+
+This command creates the `assets/js/zzzz-search-data.json` file that Jekyll uses to create your search index.
+Alternatively, you can create the file manually with [this content]({{ site.github.repository_url }}/blob/master/assets/js/zzzz-search-data.json).
