 # Git & GitHub
 
-Git is the industry standard system for code **version control**. It tracks changes to our code as we edit, permitting more complicated ways of saving and managing code. GitHub is a fancy GUI (graphical user interface) to access the tools of Git without needing CLI (command line interface), and stores code in the cloud. Using Git & GitHub, we can track everyone’s contributions from their device, see where mistakes or bugs may have occurred, and revert as necessary. You can think of this as a much more complicate version of the version control in Google Docs. 
+Git is the industry standard system for code **version control**. It helps software developing teams manage changes to their source code over time. In other words, version control keeps track of every change in your code, and it allows you to go back in time when something goes wrong. It is really helpful to prevent work done at the same time from conflicting when multiple people are working on the same project. GitHub is a website that stores code in the cloud.

 To access a static field (instance variable) or method, you need to use the **class name**, and the *dot operator*:
 
 ```java
-ClassName.methodName(); //This runs a static function that is created in the class
-ClassName.variableName; //This returns a static variable that is created in the class
+ClassName.staticMethodName(); //This runs a static function that is created in the class
+ClassName.staticVariableName; //This returns a static variable that is created in the class

+To access a regular non-static field or method, you need to use the **object variable's name** instead:
+
+```java
+objectName.methodName();
+objectName.variableName;
 ```
 
 The dot operator is used to access things contained by the object or class. This can be a variable or a function. When what you are trying to access is static you use the class. When it is not you use an object of that class.
