+## Browser compatibility and testing
+
+Currently we don't have a strict browser compatibility matrix due to our limited resources.
+We generally strive to keep mdBook compatible with a relatively recent browser on all of the most major platforms.
+That is, supporting Chrome, Safari, Firefox, Edge on Windows, macOS, Linux, iOS, and Android.
+If possible, do your best to avoid breaking older browser releases.
+
+Any change to the HTML or styling is encouraged to manually check on as many browsers and platforms that you can.

+
+## Updating higlight.js
+
+The following are instructions for updating [highlight.js](https://highlightjs.org/).
+
+1. Clone the repository at <https://github.com/highlightjs/highlight.js>
+1. Check out a tagged release (like `10.1.1`).
+1. Run `npm install`
+1. Run `node tools/build.js :common apache armasm coffeescript d handlebars haskell http julia nginx properties r scala x86asm yaml`
+1. Compare the language list that it spits out to the one in [`syntax-highlighting.md`](https://github.com/camelid/mdBook/blob/master/guide/src/format/theme/syntax-highlighting.md). If any are missing, add them to the list and rebuild (and update these docs). If any are added to the common set, add them to `syntax-highlighting.md`.
+1. Copy `build/highlight.min.js` to mdbook's directory [`highlight.js`](https://github.com/rust-lang/mdBook/blob/master/src/theme/highlight.js).
+1. Be sure to check the highlight.js [CHANGES](https://github.com/highlightjs/highlight.js/blob/main/CHANGES.md) for any breaking changes. Breaking changes that would affect users will need to wait until the next major release.
+1. Build mdbook with the new file and build some books with the new version and compare the output with a variety of languages to see if anything changes. (TODO: It would be nice to have a demo file in the repo to help with this.)

-# mdBook
+# Introduction

-**mdBook** is a command line tool and Rust crate to create books using Markdown
-(as by the [CommonMark](https://commonmark.org/) specification) files. It's very
-similar to Gitbook but written in [Rust](http://www.rust-lang.org).
+**mdBook** is a command line tool and Rust crate to create books with Markdown. The output resembles tools like Gitbook,
+and is ideal for creating product or API documentation, tutorials, course materials or anything that requires a clean,
+easily navigable and customizable presentation. mdBook is written in [Rust](https://www.rust-lang.org); its performance
+and simplicity made it ideal for use as a tool to publish directly to hosted websites such
+as [GitHub Pages](https://pages.github.com) via automation. This guide, in fact, serves as both the mdBook documentation
+and a fine example of what mdBook produces.

-What you are reading serves as an example of the output of mdBook and at the
-same time as a high-level documentation.
+mdBook includes built in support for both preprocessing your Markdown and alternative renderers for producing formats
+other than HTML. These facilities also enable other functionality such as
+validation. [Searching](https://crates.io/search?q=mdbook&sort=relevance) Rust's [crates.io](https://crates.io) is a
+great way to discover more extensions.

-mdBook is free and open source, you can find the source code on
-[GitHub](https://github.com/rust-lang/mdBook). Issues and feature
-requests can be posted on the [GitHub issue
-tracker](https://github.com/rust-lang/mdBook/issues).
+## API Documentation

-## API docs
+In addition to the above features, mdBook also has a Rust [API](https://docs.rs/mdbook/*/mdbook/). This allows you to
+write your own preprocessor or renderer, as well as incorporate mdBook features into other applications.
+The [For Developers](for_developers) section of this guide contains more information and some examples.

-Alongside this book you can also read the [API
-docs](https://docs.rs/mdbook/*/mdbook/) generated by Rustdoc if you would like
-to use mdBook as a crate or write a new renderer and need a more low-level
-overview.
+## Markdown
+
+mdBook's [parser](https://github.com/raphlinus/pulldown-cmark) adheres to the [CommonMark](https://commonmark.org/)
+specification. You can take a quick [tutorial](https://commonmark.org/help/tutorial/),
+or [try out](https://spec.commonmark.org/dingus/) CommonMark in real time. For a more in-depth experience, check out the
+[Markdown Guide](https://www.markdownguide.org).
+
+## Contributing
+
+mdBook is free and open source. You can find the source code on
+[GitHub](https://github.com/rust-lang/mdBook) and issues and feature requests can be posted on
+the [GitHub issue tracker](https://github.com/rust-lang/mdBook/issues). mdBook relies on the community to fix bugs and
+add features: if you'd like to contribute, please read
+the [CONTRIBUTING](https://github.com/rust-lang/mdBook/blob/master/CONTRIBUTING.md) guide and consider opening
+a [pull request](https://github.com/rust-lang/mdBook/pulls).

+### Require A Certain Order
+
+The order in which preprocessors are run can be controlled with the `before` and `after` fields.
+For example, suppose you want your `linenos` preprocessor to process lines that may have been `{{#include}}`d; then you want it to run after the built-in `links` preprocessor, which you can require using either the `before` or `after` field:
+
+```toml
+[preprocessor.linenos]
+after = [ "links" ]
+```
+
+or
+
+```toml
+[preprocessor.links]
+before = [ "linenos" ]
+```
+
+It would also be possible, though redundant, to specify both of the above in the same config file.
+
+Preprocessors having the same priority specified through `before` and `after` are sorted by name.
+Any infinite loops will be detected and produce an error.

+# Demo Book
+
+This is a simple demo book, which is intended to be used for verifying and validating style changes in mdBook.
+This contains dummy examples of various markdown elements and code languages, so that one can check changes made in mdBook styles.
+
+This rough outline is :
+
+- individual : contains basic markdown elements such as headings, paragraphs, links etc.
+- languages : contains a `hello world` in each of supported language to see changes in syntax highlighting
+- rust : contains language examples specific to rust, such as play pen, runnable examples etc.
+
+This is more for checking and fixing style, rather than verifying that correct code is generated for given markdown, that is better handled in tests.
