-# A simple Makefile
+# Motivation 
 The `make` program is intended to automate the mundane aspects of transforming source code into an executable. 
 The advantages of `make` over scripts is that you can specify relationships between the elements of your program
 to `make`. With the knowledge of the relationships and timestamps it figures out the necessary steps to be
 redone to produce the desired program each time.
 
+## A simple Makefile
 The specification that `make` uses is saved in a file named _makefile_. Here is a _makefile_ to build the
 traditional "Hello, World" program.
 
@@ -23,15 +24,29 @@ A _makefile_ contains a set of rules to build an application. The first rule see
 _default rule_. A _rule_ consists of three parts: the target, its prerequisites, and the command(s) to peform:
 
 ```makefile
-target: prerequisite1 prerequisite2
+target1: prerequisite1 prerequisite2
     command1
     command2

+target2(=prerequisite1): prerequisite3 prerequisite4 prerequisite5

 ```
 
 The _target_ is the file that must be made. The _prerequisites_ or _dependents_ are those files that must
 exist before the target can be successfully created. And _commands_ are those shell commands that will
 create the target from the prerequisites.
 
+## A Dependecy Graph
+![A Dependency Graph](img/dependency_graph.001.jpeg)
 When `make` evaluates a rule, it begins by finding the files indicated by the prerequisites and target. 
 If any of the prerequisites has an associated rule, `make` attempts to update those first. Next, the target
 file is considered. If any prerequisite is newer than the target, the target is remade by executing the
