Lesson A-9 (Setting Up the Raspberry Pi)
In order to open the downloaded .zip file, previous instructions were to right-click the file and select Archiver from the list. A change was recently made to Raspbian that removed this option from the list. The .zip file can now be opened automatically using Archiver by double clicking on the file with the left mouse button. Lesson A-9 has been updated to include this new method of opening the file.
