-## Embellished code excerpts
-
-In some repos, code excerpts not only serve to associate a code block with its
-originating source, but the processing instruction guides Jekyll plugins at site
-compile time. The rendered code is displayed in an embellished bordered box with
-an (optional) header (usually containing the originating file name and code
-region name), as well as an interactive copy-code button.

-## Jekyll
-
-We use the [Jekyll][] site generator, leaving most of its configuration options
-at their [default settings][Default configuration], 
-including use of Kramdown as the Markdown processor 
-and [Rouge][] as the default syntax highlighter.
-
-To see a list of the languages you can use with <code>```</code>, see
-Rouge's [list of supported languages and lexer][languages].
-The most common languages we use are `dart`, <code>console</code> (or its equivalent,
-<code>terminal</code>), <code>nocode</code>, and <code>yaml</code>.
-
-## Ruby gems and the bundler
-
-Jekyll is written in Ruby, so we use the [bundler][] (the equivalent of Dart's
-pub) to manage gems (the equivalent of pub packages). Each site's `Gemfile`
-specifies the gems it uses, possibly constraining gem versions (similar to what
-you'd do using a `pubspec.yaml` file). The bundler creates a `Gemfile.lock`
-which (transitively) lists the gems and gem versions actually used for the site.
-
-For optimal sharing of resources across sites, ensure that the sites' `Gemfile`s
-are kept as in sync to the extent practical / possible.
-
-## Jekyll plugins
-
-The main third-party Jekyll plugins we use are the following:
-
-- [jekyll-toc][] for auto-generation of page table of contents.
-
-We share custom plugins across sites. These can be found under [src/_plugins][].
-To use a shared plugin, create a symlink from the plugin in
-`site-shared/src/_plugins` to the repo's `src/_plugins` folder.

 ## Code blocks
 
-There are two ways to document code blocks on our sites:
+Use standard markdown syntax for fenced code blocks.
 
- 1. Use standard markdown syntax for fenced code like this:
-
-    ````markdown
-    ```dart
-    class C { ... }

- 1. Use the [prettify][] Jekyll block tag, supported via a custom plugin

-    Only use if you need code highlighting and the snippet
-    is not a code-excerpt.

-### **PREFER** using ``` fenced markdown for **code blocks**
-
-Standard markdown syntax is recognized by many IDEs as well as online editors
-and viewers like those available on GitHub. These tools offer convenient syntax
-highlighting and more. Markdown syntax can be used in site pages as well as API
-documentation.
-
-For these reasons, prefer standard markdown code-block syntax over use of the
-Jekyll prettify block tag.
-
-Use the `prettify` block tag if you need support for code highlighting, and your
-site isn't using the [markdown_with_code_excerpts.rb][] plugin.
