+Procedure of Data model and Schemas validation.
+===============================
+
+run_tests.sh script is able to validate data model by schemas and test pillars.
+It supports versioned and unversioned schemas and pillars. Schemas and pillars must contains yaml format.
+
+Unversioned items must be avaible in:
+
+.. code-block:: text
+
+    {FORMULA_NAME}/{FORMULA_NAME}/schemas/
+    {FORMULA_NAME}/tests/pillar/
+
+Versioned items must be avaible in:
+
+.. code-block:: text
+
+    {FORMULA_NAME}/{FORMULA_NAME}/schemas/{version}/
+    {FORMULA_NAME}/tests/pillar/{version}/
+
+You can run run_tests.sh  by following command:
+
+.. code-block:: shell
+
+    # cd <formula repository>
+    ./tests/run_tests.sh
+
+You can run run_tests.sh which inlude schema validation if schemas present by following command:
+
+.. code-block:: shell
+
+    # cd <formula repository>
+    ./tests/run_tests.sh model-validate
+
+Example schemas:
+
+.. code-block:: yaml
+
+    %YAML 1.1
+    ---
+    "$schema": "http://json-schema.org/draft-06/schema#"
+    title: {{cookiecutter.service_name}} daemon role
+    description: |
+      {{cookiecutter.service_name|capitalize}} daemon, server role
+    type: object
+    additionalProperties: false
+
+    required:
+      - enabled
+
+    properties:
+      enabled:
+        description: |
+          Enables {{cookiecutter.service_name}} daemon service
+        type: boolean
+
+Example pillar:
+
+.. code-block:: yaml
+    {{cookiecutter.service_name}}:
+      {{cookiecutter.role_name}}:
+        enabled: true
