-This is an in-progress static blog generator.
+This is an in-progress static website/blog generator.
 
 Don't use it yet. I'm not done.
+
+In lieu of documentation, for now here are a couple of relavant points:
+
+* Implemented in Lua.
+* Heavily oriented around convention over configuration.
+* Templates can be Cosmo, Haml, Markdown, and others to come.
+* All files can have arbitrary Lua header blocks to set up local template
+  variables, or do pretty much whatever you want.
+* Will come with some helpers for building common tags, doing pagination, etc.
+* Will come with a scaffold generator to create common types of sites.
+* Will support sites with any number of different types of syndicated content / feeds.
+* Will support building large colletions of similar pages out of an SQLite database.
+* Global configuration is done via headers in the main layout file; there's no
+  "config" file.
+
+In the mean time, if you want to see what this does, take a look at the files
+in the sample directory and the output of running the tests:

+    The Grackle app:
+    can load a directory of template files                               [P]
+    performs initialization tasks                                        [P]
+    generates the site                                                   [P]

+    Grackle templates:
+    have a base name                                                     [P]
+    have a format, defaulting to 'html'                                  [P]
+    have a renderer taken from the file extension                        [P]
+    have a layout renderer                                               [P]
+    have a dir name matching its relative location on disk               [P]
+    have a site_dir matching its relative target location on disk        [P]
+    have a site_path matching target file name and relative uri          [P]
+    have a path matching their location relative to the source dir       [P]
+    have contents                                                        [P]
+    have headers                                                         [P]
+    can evaluate their headers                                           [P]
+    a content template:
+      specifies that it is content                                       [P]
+      should default to a main layout matching its renderer              [P]
+      if Markdown, should use the default layout renderer                [P]
+      can use headers to specify layout-less rendering                   [P]
+      for rendering:
+        can be Cosmo                                                     [P]

+    a layout template:
+      specifes that it is a layout                                       [P]
+      can be a sub-layout                                                [P]
+      should not have a layout if it is a main layout                    [P]
+      for rendering:
