We add the following level-3 header to help people identify text they may wish to skip if they wish for a greater challenge: ``` ``` After that notice we add: ``` **If you want a greater challenge, don't read any further**: just try to understand the program via the source. If you get stuck, come back and read below for additional hints and information. ``` And sometimes follow with: ``` ``` Or sometimes follow with: ``` ``` Where the alt code impacts a "greater challenge", we add instead: ``` **If you want a greater challenge, don't read any further**: just try to understand the program without looking at the Alternate code. If you get stuck, come back and look at the Alternate code. ``` And where a given command impacts a "greater challenge", we add instead: ``` **If you want a greater challenge, don't read any further**: just try to understand the program without running the command below. If you get stuck, come back and run the following command: ``` Perform `make www` to perform the above and test under macOS.
