+Usage
+=====
+
+Prerequisites: Analytic enabled, Vehicle added to Vehicle Categories.
+
+1. Browse to "Fleet / Configuration / Categories" and define an Analytic
+   Account on a Category
+2. Create a new invoice from "Accounting / Vendors / Bills / [+ New]"
+3. On the invoice line, set a vehicle belonging to the Category modified
+   at step 1. To view the "Vehicule" column on invoice lines, do not
+   forget to add the column.
+4. Look at the Analytic Distribution: the Analytic Account previously
+   defined on the Category is added at 100%.
+
+Warning: this analytic is very simply merged / added to the existing
+analytic distribution, which may lead to more than 100% distribution.
