I am currently working on the readability problem in pst2. I followed the 'getting started' instructions to create and open the file in the readability directory, however, I am still getting a "make: *** No rule to make target 'readability'. Stop." Error.
I've included a picture of my screen if that helps. As you can see I (think) I am in the right directory with the right file Any advice would be helpful! Thank you.
