 - The `config.rb` file contains the [main configuration](/customization/configuration/) of ArchivesSpace.
+- The `data` directory is the ArchivesSpace [data directory](/customization/configuration/#appconfigdata_directory).
+- The `database` directory is the storage of the MySQL instance.
+- The `plugins` directory is there to accommodate any [plugins](/customization/plugins/) you wish to install.
+- The `solr` directory is where the solr index is persisted.
+- In the `sql` directory you can put your `.sql` database dump file to initialize the new database, see next section.
 - `docker-compose.yml` contains all the information required by Docker to build and run ArchivesSpace.
 - `.env.docker.db` contains the credentials used by archivespace to access its MySQL database. It is recommended to change the default root and user passwords to something safer.
 - `.env.docker.prod` contains the database connection URI which should also be [updated accordingly](/customization/configuration/#database-config) after the database user password is updated in the step above.
