+## How to run
+
+First you need to supply a file called *text.txt* in the same directory as the final compiled program.
+Compile the program with a compiler like *ghc*. ("stack ghc sentence_generator.hs")
+Last, run this program with the length of the randomly generated sentence as a command line argument.
