FPS Doc Error?

Tried re reading the FPS(1) Docs and I think There's a slight error.

Page 7 Adding missile explosions:
Explanation on #3

Code (csharp):

1.  
2. The object that we want to instantiate is the Explosion prefab that we created earlier. Blah Blah Blah

I don't think the explosion prefab was created, but on page 8 after #4 explanation:

Code (csharp):

1.  
2. -Firstly, create a new prefab (call is Explosion), etc. etc

Not unless I miss it.
