 `chmod a+x sunday.rb`).
 
+## Configuration

+sunday.rb has a few configurable variables.

+`THOUGHTS_DIR` should point to the directory where you will submit your
+thoughts. More details about it under "Adding thoughts" below. Defaults to
+`/srv/thoughts`, make sure to create this directory if you keep the default.

+Change `heading` to contain a personalized heading for your Sunday Corner.
+
+You can also change the `no_thoughts` message which will appear on a Sunday if
+you hadn't added any thoughts that week.
+
+And you can also change the `not_sunday` message which will inform your
+impatient visitors to wait until next Sunday for the next batch of thoughts.

 ## Thinking thoughts
 
 This one is hard. But not as hard as you might think!

 At it's simplest, just point `THOUGHTS_DIR` in sunday.rb to a directory where
 you will manually create thoughts files. A thoughts file's filename is the date
 of the Sunday on which it will be displayed (in YYYY-MM-DD format). Its contents
-are your thoughts throughout the week, separated by newlines.
+are your thoughts throughout the week.
+
+### Making it even easier
+
+The think.rb script makes adding thoughts even easier (doesn't help with the
+thinking thoughts part, unfortunately). It:
+
+* Generates the correct filename for the thoughts file based on when the next
+  Sunday is.
+* If it already exists, copies the remote thoughts file for next Sunday from
+  your remote.
+* Drops you into an editor to edit the thoughts file.
+* Once you're done editing, copies it back to your remote.
+
+For it to work properly, make sure `THOUGHTS_DIR` in think.rb points correctly
+to your remote thoughts directory.
+
+The script requires `scp` as a dependency, but that usually comes with SSH,
+which you probably already have.
