+Brightway2 will determine that you are starting it for the first time. You will need to create a :ref:`data-directory` - a writable directory where all data will be stored.
+Brightway2 comes with some basic metadata - LCIA methods and a biosphere database. They will be automatically downloaded.
All Brightway2 data is stored in a data directory, but the location of the directory can be chosen by the user. The data directory is just a bunch of subdirectories and files, so it is safe for backup programs or sync services like Dropbox.
