+This module allows you to show the cumulated balance, both in the company
+currency and in the original currency, on the general ledger and partner ledger
+menus, which is an aid for accountants that need to check the evolution of the
+balances.
+
+**Table of contents**
+
+.. contents::
+   :local:
+
+Configuration
+=============
+
+To see all the menus, make sure:
+
+* Your user is member of the group
+  "Technical Settings / Show Full Accounting Features"
+* The page is running in debug mode or you have the `base_technical_features`
+  module installed and belonging to such group.
+
+Usage
+=====
+
+#. Go to *Invoicing > Accounting > General Ledger* or
+   *Invoicing > Accounting > Partner Ledger*
+#. Two new columns will be available:
+
+   * Cumulated Balance
+   * Cumulated Balance in Currency
+
+Known issues / Roadmap
+======================
+
+* For v14, there's a similar feature, but it doesn't cumulate in an absolute way like
+  this one, and there's no cumulated in amount currency, so this module may be fully
+  preserved.
+* There's no support for filtering at the same time by several entries state (posted,
+  not posted, cancel, etc).
+* In the partner ledger, removing the group by partner won't make the cumulated balances
+  to be considered globally by account.
+
