+The module allows to add advance payments on sales and then use them on
+invoices.
+
+**Table of contents**
+
+.. contents::
+   :local:
+
+Usage
+=====
+
+To use this module, you need to:
+
+-  Go to a sale order.
+-  Click on "Pay Sale Advance".
+-  Select the Journal and specify the amount of the advanced payment.
+-  "Make Advance Payment".
+
+When generating the invoice, the system displays the advanced payments,
+select those you want to add to the invoice.
+
+Known issues / Roadmap
+======================
+
+Split several computed values in separate fields (mls, advance_amount,
+amount_residual). This allows a better comprehension of logic, and a
+better inheritance possibility.

+<h1><a class="toc-backref" href="#toc-entry-1">Usage</a></h1>
+<p>To use this module, you need to:</p>
+<ul class="simple">
+<li>Go to a sale order.</li>
+<li>Click on “Pay Sale Advance”.</li>
+<li>Select the Journal and specify the amount of the advanced payment.</li>
+<li>“Make Advance Payment”.</li>
+</ul>
+<p>When generating the invoice, the system displays the advanced payments,
+select those you want to add to the invoice.</p>
+</div>
+<div class="section" id="known-issues-roadmap">
+<h1><a class="toc-backref" href="#toc-entry-2">Known issues / Roadmap</a></h1>
+<p>Split several computed values in separate fields (mls, advance_amount,
+amount_residual). This allows a better comprehension of logic, and a
+better inheritance possibility.</p>
