+There are three records for configuring the Patchwork service.  The

+within the HTTPD service.
+
+The @code{settings-module} field within the @code{<patchwork-configuration>}
+record can be populated with the @code{<patchwork-settings-module>} record,
+which describes a settings module that is generated within the Guix store.
+
+For the @code{database-configuration} field within the
+@code{<patchwork-settings-module>}, the
+@code{<patchwork-database-configuration>} must be used.
+
+@deftp {Data Type} patchwork-configuration

+following parameters:
+
+@table @asis
+@item @code{patchwork} (default: @code{patchwork})
+The Patchwork package to use.
+
+@item @code{domain}
+The domain to use for Patchwork, this is used in the HTTPD service virtual
+host.
+
+@item @code{settings-module}
+The settings module to use for Patchwork. As a Django application, Patchwork
+is configured with a Python module containing the settings. This can either be
+an instance of the @code{<patchwork-settings-module>} record, any other record
+that represents the settings in the store, or a directory outside of the

+The path under which the HTTPD service should serve the static files.
+

+Patchwork, as a Django web application uses a secret key for cryptographically
