 NodeToJS is a module/library at once: a module for NodeJS and a library for Javascript (JS). It allows to create text based apps/games that can be executed and work both in the terminal (for Windows, Linux or Mac) and in a web browser. That is, with the same code you will create a CLI app/game and a text-based webapp/webgame.
 
 ### Use:
-The minimum files you need are three: a wrap file (game.html), the NodeToJS module/library (NODEtoJS.js), and a NodeJS or Javascript file that starts your js application.
+The minimum files you need are four:
+    -     A wrap file:                                                     app.html
+    -     A monospace font. I recommend:                                   HP_100LX_10x11.woff
+          You can get old PC fonts here: https://int10h.org/oldschool-pc-fonts/fontlist/
+    -     The NodeToJS module/library:                                     NODEtoJS.js
+    -     Your main .js file.                                              app.js
+
+### Hello world example.
 
 1. Your HTML wrap file (for example app.html) will load the NodeToJS library (NodeToJS.js) and will load the starter NodeJS/Javascript script of yout app (app.js in this example). You also have to add NodeToJS.HTMLMODE=1 right after loading the library/module and before loading your scripts.
