+
+Installation
+============
+
+This module depends on ``base_tier_validation``. You can find it at
+`OCA/server-ux <https://github.com/OCA/server-ux>`__
+
+Configuration
+=============
+
+To configure this module, you need to:
+
+1. Go to *Settings > Technical > Tier Validations > Tier Definition*.
+2. Create as many tiers as you want for Purchase Order model.
+
+Usage
+=====
+
+To use this module, you need to:
+
+1. Create a Purchase Order 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 click on *Confirm Order*.
+
+Additional features:
+
+-  You can filter the POs requesting your review through the filter
+   *Needs my Review*.
+-  User with rights to confirm the PO (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.
+

+To use this module, you need to:
+
+1.  Create a Purchase Order 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 click on *Confirm Order*.
+
+Additional features:
+
+- You can filter the POs requesting your review through the filter
+  *Needs my Review*.
+- User with rights to confirm the PO (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.
