-Inputs for fibonacci-seq
+**** Simple example of using a source block as a function
+
+     First let's look at a very simple example. The following source
+     block defines an org-babel function that will square its input.
+
+#+srcname: square(x)
+#+begin_src python
+x*x
+#+end_src
+
+In the org-mode file that looks like this:
+: #+srcname: square(x)
+: #+begin_src python
+: x*x
+: #+end_src
+
+
+Now we use the source block:
+
+: #+lob: square(x=6)
+
+#+lob: square(x=6)
+
+#+resname: square(x=6)
+: 36
+
+**** A more complex example: using an org-table as input
+
+     In this example we're going to define a function to compute a
+     Fibonacci sequence, and we're going to make it take its input
+     from a table in the org-mode buffer.
+
+     Here are the inputs for fibonacci-seq:
