In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We can include other contexts through the use of the include directive."

A block of code is set as follows:

<tr>
    <td>Fake Book</td>
    <td>This is a description of a fake book</td>
    <td><a href=""/buy/book1"">Buy Fake Book</a></td>
</tr>

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "For instance, you might have a Submit button on a page and after it triggers a save of the page's Model you want it to redirect the user to a different route."
