 Chart Setup
 -----------
 
-When the Dominican chart ``account_do.do_account_root`` is selected, the chart
-creation wizard proposes:
+The module provides two complete chart roots:
 
-* ``account_do.do_account_110201`` as the default receivable account;
-* ``account_do.do_account_210101`` as the default payable account.
+* ``account_do.do_account_root_en`` for English accounting data;
+* ``account_do.do_account_root_es_419`` for Dominican Spanish accounting data,
+  using Tryton's ``es_419`` language until ``es_DO`` is available.
 
-Fiscal Metadata
----------------
+When the English chart is selected, the chart creation wizard proposes:
 
-The module extends ``account.tax.template`` and ``account.tax`` with:
+* ``account_do.do_account_110201_en`` as the default receivable account;
+* ``account_do.do_account_210101_en`` as the default payable account.
 
-* ``tax_kind``;
-* ``tax_fiscal_type``;
-* ``tax_application``;
-* ``dgii_legal_reference``;
-* ``dgii_legal_article``;
-* ``dgii_form_hint``;
-* ``dgii_fiscal_status``.
+For the Spanish chart, the corresponding defaults are
+``account_do.do_account_110201_es_419`` and
+``account_do.do_account_210101_es_419``.
 
-These fields classify Dominican taxes without duplicating DGII report box
-mapping. Reporting modules should use them together with account and tax codes.
+The selected language is permanent accounting data. Changing a user's
+interface language does not rename an existing chart.
+
+Taxes
+-----
+
+The module defines Dominican tax groups, tax templates, tax codes, and tax
+rules using the standard models from :mod:`account`.  Each tax template keeps
+its legal basis in ``legal_notice`` and uses ``start_date`` and ``end_date``
+when a rate has a limited period of validity.
+
+DGII form classifications and form-box mappings are intentionally outside the
+accounting localization.  Reporting modules can derive fiscal totals from the
+stable tax and tax-code identifiers provided by this module.
