Looks like the email finally got sent to the right person at my company. Who knows how long it will take for them to get the FSF disclaimer back to me...

Now that I'm on holiday, I've got a little more time to contribute to Worg. Here's a few patches showing what I've come up with. I'll finish it up in the next few days, hopefully.  Not sure if the patches are formed correctly,  sorry about that if not. It's late here and I wanted to show progress. I'll worry about those kinds of details later. :)

+# - Brief description of language.
+A shell is a user interface for interacting with system services.
+File management, process execution, and operating system monitoring
+can all be done with a shell. Many shells are plain text only whereas
+some support graphics or are themselves fully graphical. Similarities
+exist between shells and, though standards exist (such as
+POSIX[fn:1]), there is no guarantee that what works in one shell will
+work in another. Each shell is a separate application.
+
+Shells often provide a programming language as well as access to
+system utilities, such as the GNU Core Utilities[fn:2]. Users can
+stitch utilities together or create their own.
+
+# - Range of typical uses within Org Mode.
+Org Babel lets users run commands[fn:3] in separate shells...
+
+: #+begin_src sh :results output
+:   echo PID: $$
+: #+end_src
+: 
+: #+RESULTS:
+: : PID: 9952
+: 
+: #+begin_src sh :results output 
+:   echo PID: $$
+: #+end_src
+: 
+: #+RESULTS:
+: : PID: 9990
+: 
+...or as part of a shared session.
+
+: #+begin_src sh :results output :session shared
+:   echo PID: $$
+:   export X=1
+: #+end_src
+: 
+: #+RESULTS:
+: : PID: 9742
+: 
+: #+begin_src sh :results output :session shared
+:   echo PID: $$
+:   echo X was set to $X
+: #+end_src
+: 
+: #+RESULTS:
+: : PID: 9742
+: : X was set to 1
+
+Shell blocks can run as standalone scripts or chained processes, be
+tangled, use args, work with stdin, have shebangs, and more.
+    
 * Requirements and Setup
-  - Installation and configuration of language software
-  - Emacs configuration
-  - Org-mode configuration (org-babel-do-load-languages)
+# - Installation and configuration of language software
+Org Babel can run many different shells, including [[https://www.gnu.org/software/bash/][sh]], [[https://www.gnu.org/software/bash/][bash]], [[https://www.zsh.org/][zsh]],
+[[https://fishshell.com/][fish]], [[https://www.grymoire.com/unix/csh.html][csh]], [[https://www.in-ulm.de/~mascheck/various/ash/][ash]], [[http://gondor.apana.org.au/~herbert/dash/][dash]], [[http://www.kornshell.org/][ksh]], [[https://www.mirbsd.org/mksh.htm][mksh]], and [[https://packages.qa.debian.org/p/posh.html][posh]].  The primary requirement is
+that the shell be installed on the system.
+
+# - Emacs configuration
+# - Org-mode configuration (org-babel-do-load-languages)
+Once the shell is installed on the system, the Org Babel shell
+language facility must be set to load[fn:4]:
+
+#+begin_example emacs-lisp
+;; active Babel languages
+(org-babel-do-load-languages
+ 'org-babel-load-languages
+ '((shell . t)))
+#+end_example
+
+*NOTE:* This is all that's needed, regardless of the shell you intend
+to use! The "shell" <lang> loads functionality for /all/ supported
+shells.  The car of =(shell . t)=, namely "shell", is the name of the
+Org Babel module that handles it, =ob-shell.el=.
+
+*NOTE:* The =ob-shell.el= module used to be named =ob-sh.el=. This was
+changed in Org 8.2[fn:5].
