+======Step 4======
 .  Look for it on your Desktop and rename it with your name (For example it might be called ''Screen Shot 2022-08-27 at 8.47.53 AM.png'' and if your name was Bob Smith, you might rename it ''BobS.png''
+======Step 5======
 .  Next you are to use these commands to make a .kwld text file.  Here is an example That Describes BobS.png:
-<code>

+To see your progress, you can put your text file in the same folder as the  ShowWorld.java project. Remember to update the name of your text file.
+<code java ShowWorld.java>
+import java.awt.Color;
+import kareltherobot.*;
+public class ShowWorld implements Directions
+{
+    public static void main(String[] args)
+    {
+        // change the file name to match the text file
+        // you made and put in the project folder:
+        World.readWorld("BobS.txt");
+        World.setBeeperColor(Color.BLUE);
+        World.setVisible();
+    }
+}
+</code>
+ Try removing or changing a wall in the BobS.txt file to get a feel of how the code changes the KarelWorld drawn by the ShowWorld main method.
+======Step 6 ======
+. Now it is your turn.  Make a new text file (or rename "BobS.txt" to your first anme and last initial, ending with ".txt").  Start with your first wall.  See the result with ShowWorld.java, and fix it if necessary, Try the next wall.
+When you are done, place 2 beepers in the best locations for the longest run for a MazeRunner robot.
+=== For those will experience with placeEWWall and placeNEWall ===
+For those who are used to the [[http://csis.pace.edu/%7Ebergin/KarelJava2ed/KJRdocs/index.html|placeEWWall or placeNSWall]] methods, there is a difference that you may find confusing with the parameters.  For ''eastwestwalls'' the three numbers are (street the wall goes on) (starting on avenue) (ending on ave).  For the ''northsouthwalls'': the three numbers are (Avenue the wal goes on) (Starting street) (Ending Street).  If you already coding it with place walls you can convert it with this:
+<code java World.java>
+/**
+ * This is a replacement for the World
+ * found in karelworld.jar
+ *
+ * to help you convert your placeWall statements
+ * with the format needed for a kwld text file format.
+ *

+public class World
+{
+    public static void placeEWWall(int str, int ave, int len)
+    {
+        int end = ave + len - 1;
+        String result = "eastwestwalls "+ str + " " +ave + " " + end;
+        System.out.println(result);
+    }
+    public static void placeNSWall(int str, int ave, int len)
+    {
+        int end = str + len - 1;
+        String result = "northsouthwalls " + ave + " " + str + " " + end;
+        System.out.println(result);
+    }
+}

+Alternatively your can use placeWall methods and save the world to file.
