 How to synchronize Odoo with your bank?
 =======================================
+
+Odoo is able to synchronize directly with your bank in order to get all
+bank statements imported automatically in Odoo every 4 hours. Before
+moving forward in this tutorial, you should check if your bank is
+supported. You can find it out from the `Odoo Accounting Features <https://www.odoo.com/page/accounting-features>`__

+
+Search for your bank name in the above page. If your bank appears in the
+proposition, it means it is supported by Odoo. The countries which are
+fully supported (meaning more than 95% of the banks) include: United
+States, Canada, New Zealand, Austria. More than 30 countries are
+partially supported, including: Colombia, India, France, Spain, etc.
+
+In order to connect with the banks, Odoo uses two web-services:
+
+-  Plaid: for the main banks in the U.S.
+
+-  Yodlee: for all other banks
+
+Configuration
+=============
+
+Odoo Online Users
+-----------------
+
+If you we support banks of your country, the bank integration feature
+should already been installed. If it's not installed, you can manually
+install the module **account_yodlee**.
+
+Odoo Enterprise Users
+---------------------
+
+If you plan to use a bank interface with your Odoo Enterprise
+subscription, contact `Odoo Support <mailto:online@odoo.com>`__ in
+order to get the credentials to sync Yodlee or Plaid with your bank
+accounts.
+
+Once you get your credentials, you can register them from the
+:menuselection:`Configuration --> Settings` menu of the Accounting application.
+
+Sync your bank feeds
+====================
+
+Once the Plaid or Yodlee interface is installed, you can connect Odoo to
+your bank. To do that, click on **More** on the bank of your
+choice from the accounting dashboard. In the menu, click on Settings to
+configure this bank account.

+
+Once it's done, go back to your accounting dashboard. You should see a
+**Online Synchronization** button on your bank card. Click on this button
+and fill in your bank credentials.
+
+Once you filled in your credentials, your bank feeds will be
+synchronized every 4 hours.
