# MDBook EPUB Backend
[](https://travis-ci.org/Michael-F-Bryan/mdbook-epub)
[**(Rendered Docs)**](https://michael-f-bryan.github.io/mdbook-epub/)
An experimental backend to `mdbook` which will render your document as an `EPUB`
file, suitable for viewing on e-readers and other similar devices.
> **WARNING:** Not yet production ready. May eat your laundry.
> **Note:** At the moment the default stylesheet is quite bare bones, serving
mainly to reset the styling used on various devices back to a known default.
This default isn't overly pretty, so you may want to include your own
stylesheets.
## Getting Started
Before you can use the EPUB backend, you'll need to actually install it:
```
$ cargo install mdbook-epub
```
Next you need to let `mdbook` know to use the alternate renderer by updating
your `book.toml` file. This is done by simply adding an empty `output.epub`
table.
```diff
[book]
title = "mdBook Documentation"
description = "Create book from markdown files. Like Gitbook but implemented in Rust"
author = "Mathieu David"
[output.html]
mathjax-support = true
+ [output.epub]
```
Now everything is set up, just run `mdbook` as normal and the output directory
(`book/epub/` by default) should now contain an extra file called
`mdBook Documentation.epub` (substituting in whatever your book's title is).
The `mdbook-epub` executable can be run in "standalone" mode. This is where
the backend can be used without needing to be called by `mdbook`, useful if
you only want to render the EPUB document.
```
$ mdbook-epub --standalone ./path/to/book/dir
```
## Configuration
Configuration is fairly bare bones at the moment. All you can do is add
additional CSS files and disable the default stylesheet.
```toml
[output.epub]
additional-css = ["./path/to/main.css"]
use-default-css = false
```
## Planned Features
The following features are planned (a checked box indicates it's complete). This
list is by no means complete, so feature requests are most welcome!
- [x] Make a valid `EPUB` file with the bare chapter contents
- [x] Generate a basic TOC
- [x] Nested chapters - currently they're all inserted at the top level
- [x] Include a default CSS stylesheet ([master.css])
- [ ] Actually make that stylesheet pretty enough for human consumption
- [x] Include user-defined stylesheets and themes
- [ ] Allow users to tweak the generated page by providing their own template
- [ ] Ensure the generated document is viewable on the following platforms
- [ ] Amazon Kindle
- [ ] Sony PRS-T3
## Contributing
This backend is still very much in the development phase and as such a large
number of features are missing. If you think of something you'd like please
