Withdrawing e-cash to a Taler wallet
====================================
-TODO.
+.. note::
+
+ This step is fully automated if you use the :ref:`guided automated setup <automated-regional-currency-setup>`.
+
+Users can withdraw digital cash from their bank account starting from their
+online banking as implemented by the libeufin-bank. However, in this scenario,
+the Taler wallet may not already know about an exchange that works with the
+respective currency. Thus, the protocol includes the possibility of the bank
+*recommending* an exchange service to the wallet, thus providing a sane
+default for the wallet to suggest to the user. To do so, the base URL of the
+exchange API must be specified in the libeufin-bank configuration:
+
+.. code-block:: ini
+
+ [libeufin-bank]
+ DEFAULT_EXCHANGE=${PROTO}://exchange.${DOMAIN_NAME}
+
+After changing this value, the libeufin-bank service needs to be restarted
+to make the change effective.
+
+.. note::
+
+ The user may change the default exchange from within the wallet, assuming they know of an alternative exchanges for the currency.
