In this chapter, we learned about the evolution of Wireshark and how the current interface allows you to quickly begin capturing by clicking on a sparkline, easily add columns to the interface, and use intelligent scrollbar coloring. 

You can now appreciate how each new version of Wireshark improves the application. We learned about how Wireshark developers constantly update the software as many people contribute to the success of Wireshark. We then explored the phases of packet capture, as it progresses from gathering the traffic from the network to processing it into a human-readable format that allows you to conduct an analysis. Finally, we saw how Wireshark can be resource intensive; therefore, it's important to understand why sometimes, it's better to use CLI tools such as tshark, a lightweight application for capturing packets.

In the next chapter, we will explore downloading and installing Wireshark on various OSes, such as Windows, macOS, and Linux. We will take the time to explore the different capture engines. Once you do decide to download Wireshark, we will evaluate the different available download options. During installation on a PC or Mac, you'll see the various options. Finally, we will look at the various resources that are available at https://www.wireshark.org/.
