> Publishing a book

> Once you've written your book, you may want to host it somewhere for others to view. The first step is to build the output of the book. This can be done with the mdbook build command in the same directory where the book.toml file is located:

> `mdbook build` This will generate a directory named book which contains the HTML content of your book. You can then place this directory on any web server to host it.
