-Use the compass to determine which direction you are heading.
+Display the direction that the micro:bit is facing using the compass 
+
+### ~avatar avatar
+
+Welcome! This guided tutorial will show you how to program a script that displays the direction the micro:bit is pointing. Let's get started!
+
+### ~
+
 
 ## Step 1
 
-Continuously sample the compass heading and store in the variable `degrees`:
+Create a loop that will continuously update the reading of the compass.
+
 
 ```blocks
-let degrees = 0;
 basic.forever(() => {
-    degrees = input.compassHeading();
-});
+    
+})
 ```
 
 ## Step 2
 
-If the degrees is less than 45, we are heading North:
+Store the reading of the micro:bit in a variable called `degrees`.
 
 ```blocks
-let degrees = 0;
 basic.forever(() => {
-    degrees = input.compassHeading();
-    if (degrees <= 45) {
-        basic.showString("N");
-    } else if (false) { } else { }
-});
+    let degrees = input.compassHeading()
+})
 ```
 
-### Step 3
+## Step 3
 
-Otherwise, if the degrees is less than 135, we are heading East:
+If `degrees` is less than `45`, then the compass heading is mostly pointing toward North. Display `N` on the micro:bit.
 
 ```blocks
-let degrees = 0;
 basic.forever(() => {
-    degrees = input.compassHeading();
-    if (degrees <= 45) {
+    let degrees = input.compassHeading();
+    if (degrees < 45) {
         basic.showString("N");
-    } else if (degrees <= 135) {
-        basic.showString("E");
-    } else { }
-});
-```
-
-### Step 4
-
-Otherwise, if the degrees is less than 225, we are heading East:
-
-```blocks
-let degrees = 0;
-basic.forever(() => {
-    degrees = input.compassHeading();
-    if (degrees <= 45) {
-        basic.showString("N");
-    } else if (degrees <= 135) {
-        basic.showString("E");
-    } else if (degrees <= 225) {
-        basic.showString("S");
-    } else {
     }
 });
 ```
 
-### Step 5
+## Step 4
+
+If `degrees` is less than 135, the micro:bit is mostly pointing East. Display `E` on the micro:bit.
 
-Otherwise, we are heading west. 
 
 ```blocks
-let degrees = 0;
 basic.forever(() => {
-    degrees = input.compassHeading();
-    if (degrees <= 45) {
+    let degrees = input.compassHeading();
+    if (degrees < 45) {
         basic.showString("N");
-    } else if (degrees <= 135) {
+    }
+    else if (degrees < 135) {
         basic.showString("E");
-    } else if (degrees <= 225) {
+    }
+});
+```
+
+## Step 5
+
+If `degrees` is less than 225, the micro:bit is mostly pointing South. Display `S` on the micro:bit.
+
+
+```blocks
+basic.forever(() => {
+    let degrees = input.compassHeading();
+    if (degrees < 45) {
+        basic.showString("N");
+    }
+    else if (degrees < 135) {
+        basic.showString("E");
+    }
+    else if (degrees < 225) {
         basic.showString("S");
-    } else {
+    }
+});
+```
+
+## Step 6
+
+If none of these conditions returned true, then the micro:bit must be pointing West. Display `W` on the micro:bit.
+
+```blocks
+basic.forever(() => {
+    let degrees = input.compassHeading();
+    if (degrees < 45) {
+        basic.showString("N");
+    }
+    else if (degrees < 135) {
+        basic.showString("E");
+    }
+    else if (degrees < 225) {
+        basic.showString("S");
+    }
+    else {
         basic.showString("W");
     }
 });
-```
