+# Customer
+
+Customers in Kimai are used to manage project and activities, which are then used for time-records.
+
+It is very common to have a _customer_ for your own company, to track times for administration and other internal work.
+ 
+## Creating customer
+
+Define the default values for a customer like this: 
+```yaml
+kimai:
+    defaults:
+        customer:
+            timezone: Europe/London
+            country: GB
+            currency: GBP
+```
