-  <p>Quick answer: Because its already present.</p> 
-  <p>Having understood the <a href="#deref">previous question</a>, a new 
-  question then arises:</p>
+  <p>Quick answer: The index stepping through the first operand.</p> 
+  <p>The confusion with the first index usually arises from thinking about 
+  the GetElementPtr instruction as if it was a C index operator. They aren't the
+  same. For example, when we write, in "C":</p>
+  <pre>
+  AType* Foo;
+  ...
+  X = Foo[1];</pre>
+  <p>it is natural to think that there is only one index, the constant value
+  <tt>1</tt>. This results from C allowing you to treat pointers and arrays as
+  equivalent. LLVM doesn't. In this example, Foo is a pointer. That pointer must
+  be indexed. To arrive at the same address location as the C code, you would
+  provide the GEP instruction with two indices. The first indexes through the
+  pointer, the second index the second element of the array.</p>
+  <p>Sometimes this question gets rephrased as:</p>
   <blockquote><i>Why is it okay to index through the first pointer, but 
       subsequent pointers won't be dereferenced?</i></blockquote>
