To keep things consistent, we use the +bash+ shell in all command-line examples. While other shells will behave in a similar way, and you will be able to run all the examples without it, some of the shell scripts are written specifically for the +bash+ shell and may require some changes or customizations to run in another shell. For consistency, you can install the +bash+ shell on Windows and Mac OS, and it comes installed by default on most Linux systems.
==== Donwloading the book repository
==== Downloading the book repository
All the code examples are available in the book's online repository. Because the repository will be kept up-to-date as much as possible, you should always look for the latest version in the online repository, instead of copying it from the printed book or the ebook.
You can download the repository as a ZIP bundle by visiting +github.com/lnbook/lnbook+ and selecting the green "Clone or Download" button on the right.
Alternatively, you can use the +git+ command to create a version-controlled clone of the repository on your local computer. Git is a distributed version control system that is used by most developers to collaborate on software development and track changes to software repositories. Donwload and install +git+ by following the instructions on https://git-scm.com/.
Next, we use the +make+ command to build the libraries, components and executables of the c-lightning project. This part will take several minutes to complete and will use your computers CPU and disk aggressively, so expect some noise from the fans! Running make:

We have OpenJDK 11.0.7 and Maven 3.6.1, so we're ready.

Next, we have to wait. We just created a bunch of channels, which means that our nodes broadcast a bunch of funding transactions. The channels can't be used until the funding transactions are mined with 6 confirmations. Since our Bitcoin regtest blockchain is set to mine blocks every ten seconds, we have to wait 60 seconds for all the channels to be ready to use.
