+How your customers can access their portal
+==========================================
+
+It has never been so easy for your customers to access their documents
+through a portal. Forget endless signup forms, Odoo makes it as easy as
+ABC. With eCommerce and Online Quotation apps, your customers are requested
+to create a portal account (name, email, password only) from the very first
+order confirmation or online quotation email they get from you.
+
+Sign up
+=======
+
+When clicking the link in the email or when clicking *Sign up* in the checkout
+process, your customer is directed to the *Sign up* page.

+From the portal menu all the customer history can be reviewed. The main address
+(billing) can also be modified.

+.. note::
+    If a portal user is a contact of a company (*Company* field set in customer
+    detail form), this last will see all the documents of the company and all
+    its other contacts through the portal.
