 Mistral Configuration Guide
 ===========================
 
-TBD
\ No newline at end of file
+Mistral configuration is needed for getting it work correctly
+either with real OpenStack environment or without OpenStack environment.
+
+**NOTE:** The most of the following operations should performed in mistral directory.
+
+1. Generate *mistral.conf* (if it does not already exist)::
+
+    oslo-config-generator --config-file tools/config/config-generator.mistral.conf --output-file etc/mistral.conf
+
+2. Edit file **etc/mistral.conf**.
+
+3. **If you are not using OpenStack, skip this item.** Provide valid keystone auth properties::
+
+    [keystone_authtoken]
+    auth_uri = http://<Keystone-host>:5000/v3
+    identity_uri = http://<Keystone-host:35357/
+    auth_version = v3
+    admin_user = <user>
+    admin_password = <password>
+    admin_tenant_name = <tenant>
+
+4. **If you don't use OpenStack**, provide ``auth_enable = False`` in config file::
+
+    [pecan]
+    auth_enable = False
+
+5. **If you are not using OpenStack, skip this item**. Register Mistral service and Mistral endpoints on Keystone::
+
+    $ MISTRAL_URL="http://[host]:[port]/v2"
+    $ keystone service-create --name mistral --type workflowv2
+    $ keystone endpoint-create --service_id mistral --publicurl $MISTRAL_URL --adminurl $MISTRAL_URL --internalurl $MISTRAL_URL
+
+6. Configure transport properties in the corresponding config section: for RabbitMQ it is **oslo_messaging_rabbit**::
+
+    [oslo_messaging_rabbit]
+    rabbit_userid = <user_id>
+    rabbit_password = <password>
+    rabbit_host = <host>
+
+ **NOTE**: Make sure that backend transport configuration is correct. Example for RabbitMQ::
+
+    [DEFAULT]
+    rpc_backend = rabbit
+
+7. Configure database. **SQLite can't be used in production**. Use *MySQL* or *PostgreSQL* instead. Here are the steps how to connect *MySQL* DB to Mistral:
+
+ Make sure you have installed **mysql-server** package on your Database machine (it can be your Mistral machine as well).
+
+ Install MySQL driver for python::
+
+    pip install mysql-python
+
+ Create the database and grant privileges::
+
+    mysql -u root -p
+
+    CREATE DATABASE mistral;
+    USE mistral
+    GRANT ALL ON mistral.* TO 'root':<password>@<database-host>;
+
+ Configure connection in Mistral config::
+
+    [database]
+    connection = mysql://<user>:<password>@<database-host>:3306/mistral
+
+ **NOTE**: If PostgreSQL is used, configure connection item as below::
+
+    connection = postgresql://<user>:<password>@<database-host>:5432/mistral
+
+8. **If you are not using OpenStack, skip this item.** Update mistral/actions/openstack/mapping.json file which contains all allowed OpenStack actions, according to the specific client versions of OpenStack projects in your deployment. Please find more detailed infomation in tools/get_action_list.py script.
+
+9. Configure Task affinity feature if needed. It is needed for distinguishing either single task executor or one task executor from group of task executors::
+
+    [executor]
+    host = my_favorite_executor
+
+ Then, this executor can be referred in DSL by::
+
+    ...Workflow YAML...
+    my_task:
+      ...
+      target: my_favorite_executor
+    ...Workflow YAML...
+
+10. After that try to run mistral engine and see it is running without any error::
+
+     mistral-server --config-file <path-to-config> --server engine
+
