Building the Book

The book is made using mdbook. To install it you'll need cargo installed. If you don't have any Rust tooling installed, you'll need to install rustup first. Follow the instructions on the site in order to get set up.

Once you have that done then just do the following:

$ cargo install mdbook

Make sure the cargo install directory is in your $PATH so that you can run the mdbook binary.

Now just run this command from root directory of your local git clone of the book:

$ mdbook serve

This will serve the book locally on the localhost:3000 port for you to read in your web browser.

If you wish to contribute fixes or changes to this book, running mdbook serve in your terminal will automatically generate and serve the files as you make changes.

Alternatively, the files are all written in Markdown so if you don't want to generate the book to read them, then you can open the *.md files in the src directory.
