 The file system can be read in two modes, either in a block or non blocking
 mode (similar to async calls in C#)

+Below is an example of exactly that. The 'Sync' calls are ones that are done in
+a blocking manner
+
+{{{
+//import read file 
+const { readFile, readFileSync } = require('fs');
+
+//read the file, blocking
+const txt = readFileSync('./sample.txt', 'utf8');

+== Packages ==
+
+Node.js's package manager is npm. It can download packages for you to use in
+your project. To start using npm in a project, run `npm init -y` to setup a
+package.json file, which is how npm keeps track of files it needs. Now to
+install a framework (for example, express), run `npm install express`, and
+thats all that is needed
+
+To include a package (which includes the several built in packages), use the
+`require()` syntax, and pass it a string argument of the name of the module.
+This system is how you can use several files on one project. To include a
+module called 'my-module', you first create a my-module.js file, the add this
+to the top of your code
+
+{{{
+const myModule = require('./my-module');
+
+console.log(myModule);
+  }}}
+  
+Then in the module file you must export code from it. In the module file, add
+the following
+
+{{{
+    module.exports = {
+        myvar : 'some value'
+    }
+  }}}
+  
+Now myModule.myvar will return 'some value'. You can use functions and the like
+here to make easy to import functionality.
