+## Java beautifier
+
+Makes java code look like it should.
+
+#### Usage
+
+Beautifies a java file.
+
+`./java-beautifier.py <a java file>`
+
+#### Example
+
+1. Create `Main.java` with the content
+    ```java
+    public class Main {
+    
+        public static void main(String[] args) {
+            System.out.println("I'm so beautiful");
+        }
+    
+        public static class UnnecessarySubClass {
+            public static void unnecessaryVoid() {
+                System.out.println("Hello, i'm unnecessary");
+            }
+        }
+    
+    }
+    ```
+
+2. Beautify the file: `./java-beautifier.py Main.java`
+
+3. Look at the beautiful output
+    ```java
+    public class Main                             {
+    public static void main(String[] args)        {
+    System.out.println("I'm so beautiful");       }
+    public static class UnnecessarySubClass       {
+    public static void unnecessaryVoid()          {
+    System.out.println("Hello, i'm unnecessary"); }}}
+    ```
