+
+What is an account type ? 
+==========================
+
+An account type is a name or code given to an account that indicates the
+account's purpose.
+
+In Odoo, Account Types are used for information purpose, to generate
+country-specific legal reports, set the rules to close a fiscal year and
+generate opening entries.
+
+Basically Account types categorize general account with some specific
+category according to its behaviour or purpose.
+
+Which are the account types in Odoo ?
+=====================================
+
+Odoo covers all accounting types. Therefore, you cannot create new
+account types. Just pick the one related to your account.

+How do I configure my accounts ?
+================================
+
+Account types are automatically created when installing a chart of
+account. By default, Odoo provides a lot of chart of accounts, just
+install the one related to your country.
+
+It will install generic accounts. But if it does not cover all your
+cases, you can create your own accounts too.
+
+.. note::
+
+	If you are a Saas User, your country chart of account is
+	automatically installed.
+
+To create a new accounts, go to the Accounting application. Open the
+menu :menuselection:`Adviser --> Chart of Accounts`, the click on the
+**Create** button.
