+# Brightway Structure
+
+## Brightway Objects
+
+Data in Brightway is structured in a hierarchy. At the top level, we
+have projects. A project is self-contained, with its own copy of data,
+LCIA methods, calculations, assumptions, and any other data you need.
+Each project is completely independent of other projects.Projects are
+saved as subdirectories in the file system.
+
+Inside a project we have a number of objects that store data. The most
+common data objects are inventory *databases* and impact assessment
+*methods*. However, non-LCA data can also be included. For example, a
+set of vehicle registrations and lifetimes could also be stored in a
+project, and used to generate fleet-based scenarios for sustainability
+assessment of mobility services.
