Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Note that I made sure it's executable via chmod +x."

A block of code is set as follows:

version: 2
jobs:
  build:
    docker:
    - image: circleci/golang:1.11
    - image: circleci/postgres:9.6-alpine

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

$ tree -L 2
.
├── LICENSE
├── README.md
├── build.sh

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "We can sync it by selecting Sync from the ACTIONS dropdown."
