+These challenges will help you display a glowing image that fades in and out at different speeds. #docs
+
+**Challenge 0**
+
+[This guided tutorial](https://test.microbit.co.uk/td/lessons/glowing-mountain/tutorial) will teach you how to create a mountain that fades out.
+
+```
+images.createImage(`
+. . . . .
+. . # . .
+. # # # .
+# # # # #
+# # # # #
+`).showImage(0)
+led.fadeOut(700)
+```
+
+**Challenge 1**
+
+Now, let's add `basic->pause(1000)` after the fade in so that there will be a 1000 millisecond delay after the fade out.
+
+```
+images.createImage(`
+. . . . .
+. . # . .
+. # # # .
+# # # # #
+# # # # #
+`).showImage(0)
+led.fadeOut(700)
+basic.pause(1000) // ***
+```
+
+**Challenge 2**
+
+After the pause, let's add `led->fade in(2000)` so that we can create a glowing effect.
+
+```
+images.createImage(`
+. . . . .
+. . # . .
+. # # # .
+# # # # #
+# # # # #
+`).showImage(0)
+led.fadeOut(700)
+basic.pause(1000)
+led.fadeIn(2000) // ***
+```
+
+**Challenge 3**
+
+Now add another `basic->pause(1000)` and `led->fade out(900)` so that the mountain can fade out again.
