To run this application, please install Node.js. The safe option is to install the LTS release.
Next, open a terminal and make sure the command node -v works as expected. It
should output the version number.
Then get yourself a copy of this application. It should live in its own directory.
Open up a terminal and cd your way to wherever the application directory is.
In it, run npm i to install the application's dependencies. Do not close the
terminal yet, we need it again.
Put your data text file into the directory.
Finally, run node . filename.txt in the terminal you opened before. Make sure
to replace filename.txt with the actual filename.
