+# Map Build Process
+
+The parts to build a map - layers, behaviors, maps, and styles - are loaded
+with menu loaders, like `openlayers_layer_export_load`. They should not be
+loaded manually because menu loaders do the necessary instantiation and
+cache-clearing.
+
+In 2.x, layers, behaviors, and styles contain more logic for 'rendering
+themselves' than before, but cannot completely exist on their own. The functions
+that iterate over included layers, behaviors, and styles are in
+`openlayers.render.inc`.
+
+`openlayers_build_map` and `openlayers_render_map` are the two essential parts
+of the actual map building and rendering, and are included in
+`openlayers.module`.
+
+The map building process does not directly deal with map data: in the case that
+Drupal is rendering data (as in openlayers_views), this functionality is
+encapsulated in the `render()` method of the layer type. See
+`modules/openlayers_views` for an example of how this works.
