+* Pre-Quantum Electrodynamics lecture notes (html export)
+
+In this repo, you will find
+`J.-S. Caux <https://jscaux.org>`_'s
+`Pre-Quantum Electrodynamics <https://jscaux.org/ln/pqed>`_
+online lecture notes (exported to html).
+
+** Pulling the notes to your local machine
+
+On the command line,
+#+BEGIN_SRC shell
+  git clone https://jscaux.org/git/jscaux/pqed_html.git
+#+END_SRC
+This will create a directory =pqed_html=. If you prefer pulling into
+a differently-named directory (/e.g./ =my_pqed_dir=), just do
+#+BEGIN_SRC shell
+  git clone https://jscaux.org/git/jscaux/pqed_html.git my_pqed_dir
+#+END_SRC
+
+Make sure you regularly pull the latest version
+(updates are frequently pushed; check the =Created= date at the
+bottom of the page to see which version you're using):
+#+BEGIN_SRC shell
+  cd pqed_html
+  git pull origin master
+#+END_SRC
+
+** Using the notes locally
+
+Pretty easy: just open the =index.org= page (or any other
+=.html= page in the repo) in your browser.
+
+
+** Learning git
+
+`git <https://git-scm.com/>`_ is one of those applications which
+you don't know you need until you start using it, after which you
+wonder how you could possibly have survived without it in the past.
+
+Though you don't need anything more than the instructions above,
+it's well worth your while to `RTFM <https://git-scm.com/doc>`_.
