 Mistral
 =======
 
-Task service for OpenStack cloud
+Task Orchestration and Scheduling service for OpenStack cloud
+
+
+Running in development mode
+---------------------------
+
+### Installation
+First of all, in a shell run:
+
+*tox*
+
+This will install necessary virtual environments and run all the project tests. Installing virtual environments may take significant time (~10-15 mins).
+
+### Mistral configuration
+
+Open *etc/mistral.conf* file and fix configuration properties as needed. For example, *host* and *port* specified by default may not be desired in a particular environment.
+
+### Running Mistral API server
+To run Mistral API server perform the following commands in a shell:
+ 
+*tox -epy27 -- /mistral/cmd/api.py --config-file etc/mistral.conf*
