# Unzip the Homebrew Launcher Channel (will be referred to as the HBLC from here)
#* You can rename the containing folder for organizational purposes. For these instructions, we will rename it from <code>homebrew_launcher_channel.v2.1</code> to <code>my-cool-app</code>
# Unzip CDecrypt
# Create a file named <code>keys.txt</code> in the same directory as the CDecrypt executable, and paste the Wii U Common Key on the first line
# Open a terminal and navigate to the location of the CDecrypt executable
# Use CDecrypt to decrypt the contents of the HBLC
#* For example, if you have the contents of the HBLC in a folder named <code>my-cool-app</code>, the command would be something like: <code>CDecrypt "/path/to/my-cool-app/" "/path/to/my-cool-app/"</code>
#* The folder with the HBLC's contents should now contain three new folders: <code>code</code>, <code>content</code>, and <code>meta</code>. Delete everything in this directory <strong>except</strong> these three folders
