 ==========================================
 Import Coda statement files (Belgium only)
 ==========================================
+
+CODA is a file format for bank statements in Belgium. Most Belgian
+banks, as well as the Isabel software, allows to download a CODA file
+with all your bank statements.
+
+With Odoo, you can download an CODA file from your bank or accounting
+software and import it directly in Odoo. This will create all bank
+statements.
+
+.. tip:: 
+    Test now the feature `with this sample CODA file <https://drive.google.com/file/d/0B5BDHVRYo-q5UVVMbGRxUmtpVDg/view?usp=sharing>`__
+
+Configuration
+=============
+
+Install the CODA feature
+------------------------
+
+If you have installed the Belgian Chart of Account provided with Odoo,
+the CODA import feature is already installed by default. In such a case,
+you can move directly to the next section `Import your first coda
+file <InstallCoda_>`_
+
+If CODA is not activated yet, you need to do it first. In the Accounting
+application, go to the menu :menuselection:`Configuration --> Settings`. From the
+accounting settings, check the option **Import of Bank Statements in
+.CODA Format** and apply.
+
+Import your first CODA file
+---------------------------
+
+Once you have installed this feature, you can setup your bank account to
+allow importing bank statement files. To do this, go to the accounting
+**Dashboard**, and click on the button **More** on the bank account card. Then, click
+on **Import Statement** to load your first CODA file.

+Load your CODA file in the following screen and click **Import** to
+create all your bank statements.

+If the file is successfully loaded, you will get redirected to the bank
+reconciliation screen with all the transactions to reconcile.

+
+Importing CODA files
+====================
+
+After having imported your first file, the Odoo accounting dashboard
+will automatically propose you to import more files for your bank. For
+the next import, you don’t need to go to the **More** button anymore, 
+you can directly click on the link **Import Statement**.
+
+.. image:: media/coda03.png
+   :align: center
+
+Every time you get a statement related to a new customer / supplier,
+Odoo will ask you to select the right contact to reconcile the
+transaction. Odoo learns from that operation and will automatically
+complete the next payments you get or make to these contacts. This will
+speed up a lot the reconciliation process.
+
+.. note::
+    Odoo is able to automatically detect if some files or transactions 
+    have already been imported. So, you should not worry about avoiding 
+    to import two times the same file: Odoo will check everything for you 
+    before creating new bank statements.
