+This module extends the functionality of fleet management to link each
+vehicle to one or more analytic accounts (cost centers), using the same
+analytic distribution field used everywhere else in Odoo accounting. It
+also gives direct access, from the vehicle form, to every purchase order
+that shares an analytic account with the vehicle.
+
+It also makes the analytic accounts of a purchase order searchable from
+the user interface, reusing the ``analytic_distribution`` field that the
+OCA ``purchase_analytic`` module already adds on the purchase order
+header. In Odoo that field is stored as JSON, which is not searchable
+from a regular search view out of the box; the ``analytic.mixin`` it
+relies on already solves that by exposing a computed and searchable
+``distribution_analytic_account_ids`` field, which this module simply
+adds to the Requests for Quotation and Purchase Orders search views.

+Usage
+=====
+
+To use this module you need to:
+
+1. Go to *Fleet > Vehicles* and open a vehicle.
+2. In the *Vehicle* group, set the **Analytic Distribution** of the
+   vehicle (its cost center or centers, with the percentage of each
+   one).
+3. A **Purchase Orders** smart button appears at the top of the form. It
+   shows how many purchase orders have at least one line whose analytic
+   distribution shares an analytic account with the vehicle, and opens
+   them when clicked.
+
+To filter purchase orders by analytic account:
+
+1. Go to *Purchase > Orders > Purchase Orders* (or *Requests for
+   Quotation*).
+2. Type the name of an analytic account in the search box and pick the
+   **Analytic Account** entry, or add it from the filter dropdown.
