 Additionally, if you use yt in a paper, I'd love it if you'd drop me a line to
 let me know.
 
+What are all these .yt files?
+-----------------------------
+
+By default, yt attempts to serialize a couple pieces of data that help speed it
+up in future invocations.  Specifically, the entire contents of the hierarchy,
+the parent-child relationships between the grids, and any projections of the
+entire volume that are made.
+
+The numbers that make up the filenames are taken from one of two places.  If
+your Enzo outputs the "CurrentTimeIdentifier" parameter, that is the number that it
+uses.  (This is a string of digits representing the number of seconds since the
+epoch.)  If that is unavailable, the creation time of the file as reported by
+the file system is used.
+
+This can cause problems.  Ticket #91 on the bug tracker records some of these.
+If you are creating multiple parameter files per second, this can lead to
+incorrect hierarchies, and thus incorrect behavior, inside your analysis.  In
+such cases, it is recommended that the parameter 'serialize' in the section
+'lagos' of your configuration file is set to 'False'.
+
 How can I help?

+How do I specify an axis?
+-------------------------
+
+For now, axes are specified by integers -- 0,1,2 for x,y,z.  In the next
+version, this will probably change, and allow for string-identification as
+well.

 Where can I go for support?

-===========================================
+Data Containers
+===============
 
-.. module:: lagos.BaseDataTypes
-   :synopsis: Generate containers to hold AMR data
-.. moduleauthor:: Matthew Turk <mturk at stanford.edu>
+yt provides a number of data containers, defined such that they satisfy a
+logical need.  Each of these provides only the finest-resolution cells, unless
+an option is available to restrict the levels from which they draw, as is the
+case with :class:`~yt.lagos.EnzoCoveringGrid`.
+
+Each of these implements the same primary protocol - all data values can be
+access dictionary-style:
+
+.. code-block:: python
+
+   >>> object["Density"]
+   >>> object["Density"].max()
+
+And so on.  For more information, see the
+:ref:`the tutorial topic <basic_objects>` on basic objects.

+<p>By default, yt attempts to serialize a couple pieces of data that help speed it
+up in future invocations.  Specifically, the entire contents of the hierarchy,
+the parent-child relationships between the grids, and any projections of the
+entire volume that are made.</p>
+<p>The numbers that make up the filenames are taken from one of two places.  If
+your Enzo outputs the “CurrentTimeIdentifier” parameter, that is the number that it
+uses.  (This is a string of digits representing the number of seconds since the
+epoch.)  If that is unavailable, the creation time of the file as reported by
+the file system is used.</p>
+<p>This can cause problems.  Ticket #91 on the bug tracker records some of these.
+If you are creating multiple parameter files per second, this can lead to
+incorrect hierarchies, and thus incorrect behavior, inside your analysis.  In
+such cases, it is recommended that the parameter ‘serialize’ in the section
+‘lagos’ of your configuration file is set to ‘False’.</p>

-   :synopsis: Generate containers to hold AMR data
-.. moduleauthor:: Matthew Turk <mturk at stanford.edu>
+yt provides a number of data containers, defined such that they satisfy a
+logical need.  Each of these provides only the finest-resolution cells, unless
+an option is available to restrict the levels from which they draw, as is the
+case with :class:`~yt.lagos.EnzoCoveringGrid`.
 
-.. toctree::
+Each of these implements the same primary protocol - all data values can be
+access dictionary-style:
+
+.. code-block:: python
+
+   >>> object["Density"]
+   >>> object["Density"].max()
+
+And so on.  For more information, see the
+:ref:`the tutorial topic <basic_objects>` on basic objects.
