+
+Installation
+============
+
+This module depends on ``base_tier_validation``. You can find it at
+`OCA/server-ux <https://github.com/OCA/server-ux>`__
+
+Configuration
+=============
+
+In addition, you may want to add more tiers, so:
+
+1. Go to *Settings > Technical > Tier Validations > Tier Definition*.
+2. Create as many tiers as you want for Purchase Requisition model.
+
+Usage
+=====
+
+To use this module, you need to:
+
+1. Create a Purchase Agreements triggering at least one "Tier
+   Definition".
+2. Click on *Request Validation* button.
+3. Under the tab *Reviews* have a look to pending reviews and their
+   statuses.
+4. Once all reviews are validated button to *Confirm* will be shown.
+
+Additional features:
+
+-  You can filter the Purchase Agreements requesting your review through
+   the filter *Needs my Review*.
+-  User with rights to confirm the Purchase Agreements (validate all
+   tiers that would be generated) can directly do the operation, this
+   is, there is no need for her/him to request a validation.

+  tiers that would be generated) can directly do the operation, this is,
+  there is no need for her/him to request a validation.
