 =======
 
 A LaTeX/TikZ rendering template for plotting some "quantified self" data against a UTC x-axis.
+You may need an up-to-date installation of [TeXLive](http://www.tug.org/texlive/) ([OSX](http://www.tug.org/mactex/), [Unix](http://mirror.ctan.org/systems/texlive/tlnet/install-tl-unx.tar.gz), [Windows](http://mirror.ctan.org/systems/texlive/tlnet/install-tl.zip))
+to make this work.
+
+To produce the pdf, run `make`. To open it as well, run `make open` (on OSX), or `make evince` (on Linux). I don't know about Windows.
+
+Directions
+----------
+
+There's a bunch of sample data in `meals.tex`, `misc_events.tex`, `practice.tex` (intended for a hobby), `work.tex`,
+`mood_log.txt`, and `sleep_log.txt`. I recommend linking the `.txt` files to your Dropbox:
+
+    $ mv *.txt ~/Dropbox
+    $ ln -s ~/Dropbox/mood_log.txt mood_log.txt
+    $ ln -s ~/Dropbox/sleep_log.txt sleep_log.txt
+
+Then you can edit these from anywhere you have a Dropbox client, including iOS or Android. The `.tex` files are harder
+to edit on a mobile device, but should be maintained with the discipline of journaling. Also, edit `name.tex` (-:
+
+Every week or so, you'll need to edit `dates.tex`.
+
+Future work
+-----------
+
+Ideally, all these files (especially `dates.tex`) should be automatically generated out of a database, which could
+then accept input from a Pebble app, an email parser, a Twilio parser, a Web interface, etc., etc.
+It probably should also run as a Heroku app so you don't have to worry about maintaining a TeXLive installation and
+a database server.
+Pull requests are welcome, as is nagging.
