No offense, but the help pages on the code blocks could really use
improvement.  For example,

Exporting code blocks
Nowhere does this section explain *how* you can export a code block,
nor are there any links to pages that are helpful.  As a minimum it
should include the relevant commands and the key bindings for
exporting code blocks.  Where are they?

Evaluating code blocks
The second paragraph states that only 'emacs-lisp' is enabled by
default.  Suppose I want to use something other than 'emacs-lisp',
*how* do I enable that?  The parenthetical comment states that the
Languages section lists the supoported languages but doesn't mention
that the explanation of enabling other languages is there.  Better
to not leave the reader hanging.  How about this:

"By default, the evaluation facility is only enabled for Lisp code
blocks specified as ‘emacs-lisp’.  See _Languages_ for instructions on
enabling other languages and for a list of supported languages.  See
_Structure of code blocks_ for information on the syntax used to
define a code block."
