 Building from source
 --------------------
 
-The new source format is [Sphinx](http://sphinx-doc.org), a documentation
-build tool written in [Python](http://python.org), which you will need to
-install if you want to build the document.  You can find the complete
-installation instructions
-[here](http://www.sphinx-doc.org/en/stable/install.html).
+As well as these document sources, you will need:
+
+* Sphinx.  You can find the complete installation instructions
+  [here](http://www.sphinx-doc.org/en/stable/install.html).
+
+* Sphinx makes use of [Blockdiag](https://pypi.python.org/pypi/blockdiag)
+  for some of the diagrams; you'll need that too.
+
+If you have `pip`, this command will be all you need:
 
-After you have Sphinx installed, you can build the HTML version of the
+    pip install sphinx blockdiag
+
+After you have everything installed, you can build the HTML version of the
 guide from a command prompt, like this:
 
 	make html
 
+For building the PDF version, you need a reasonably recent installation of
+TeX Live.  Release 2014 will do.  You will also need the Emerald font
+package from https://www.ctan.org/tex-archive/fonts/emerald/.  This cannot
+be installed with `tlmgr`, nor does it seem to be packaged by the usual
+Linux or BSD distributions.  Scripts for installing and uninstalling
+Emerald are provided in the `tools` directory.  When you're ready, type
+this:
+
+	make latexpdf
+
 Other formats are available; just type `make` for more details.
 
 Conversion strategy

 (major) part of the work:
 
 * Dump the text out of the PDF file
-* Convert all the text to Sphinx format
+* Convert all the 3rd edition text to Sphinx format
 * Get the online version to look good
 
 After that comes the 4th edition changes, hopefully in collaboration with
