Conventions

In this book, you will find a number of styles of text 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: "The <Play> verb lets you play audio."

A block of code is set as follows:

<?xml version="1.0" encoding="UTF-8"?>
<Response>
<Say>Twilio Best Practices is number one!</Say>
</Response>

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

<p>
   access this conference, participants should dial
   <your phone number here> and use access code {{
   $conference->access_code }}.
 </p>

Any command-line input or output is written as follows:

composer require "watson/validating:0.10.*"

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Once you've got your number, head back to the Numbers screen and click on the one you've just bought."
