 <p>If you're unsure what the above code says, skim through the <a 
href="../LangRef.html">LLVM Language Reference Manual</a> and convince yourself 
that the above LLVM IR is actually equivalent to the original function.  Once 
you’re satisfied with that, let’s move on to actually generating it 
programmatically!</p>
 
-<p>... STUFF ABOUT HEADERS ... </p>
+<p>Of course, before we can start, we need to <code>#include</code> the 
appropriate LLVM header files:</p>

<code>main()</code> will look like:</p>

 <p>The final step in creating our function is to create the instructions that 
make it up.  Our <code>mul_add</code> function is composed of just three 
instructions: a multiply, an add, and a return.  <code>LLVMBuilder</code> gives 
us a simple interface for constructing these instructions and appending them to 
the “entry” block.  Each of the calls to <code>LLVMBuilder</code> returns a 
<code>Value*</code> that represents the value yielded by the instruction.  
You’ll also notice that, above, <code>x</code>, <code>y</code>, and 
<code>z</code> are also <code>Value*</code>’s, so it’s clear that 
instructions operate on <code>Value*</code>’s.</p>
 
-<p>And that’s it!  Now you can compile and run your code, and get a wonder 
textual print out of the LLVM IR we saw at the beginning.</p>

COMPILE YOUR CODE ... </p>
+<p>The <code>llvm-config</code> utility is used to obtain the necessary 
GCC-compatible compiler flags for linking with LLVM.  For this example, we only 
need the 'core' library.  We'll use others once we start adding optimizers and 
the JIT engine.</p>
