Now that we understand the general developer flow a bit more, let's take a deeper dive into using some of the tools and approaches that you can use to share changes in source control. In this case, we will be using some specific tools to populate and manage the content of our chosen source control repository—Git. To provide an easy means to explore the benefits of a more distributed solution, we will use GitHub as a hosted instance of Git (others are available, including broader developer flow features). The following is a list of the tools that we will be using in this chapter:

• GitHub: Ensure that you have a GitHub account. Public accounts are free, but you can also use a private account for the purposes of this chapter. Download the excellent GitHub GUI for either: https://desktop.github.com/. This chapter will use the Mac edition, though not to the level that it will not be possible to find and perform equivalent operations in the Windows edition; both clients are really easy to use.

• The Salesforce DX CLI: If you have been following from the start of this book, you will have this already installed. Otherwise, download it at https://developer.salesforce.com/platform/dx. 
• Visual Studio Code with Salesforce extensions: You can download this IDE at https://code.visualstudio.com/download. Once installed, search for the Salesforce Extension Pack extension and install it.

Now that we have established our tools, the following sections will walk through further details on using them and how they fit into the process of interacting with source control.
