-## Building CloudTik
+
+# workspace commands
+cloudtik workspace   $workspace_config_file      # Create a Workspace on Cloud based on the workspace configuration file.

+You can use the command `cloudtik --help` or `cloudtik up --help` to get detailed instructions.
 
 Usually you can install CloudTik package directly through pip as above and don't need to build it from source code. If you are contributing to CloudTik, you can follow the instrucitons in [Building CloudTik](./doc/Building.md) for building.
