 - **gpus_per_node** and **ntasks_per_node**: These are Slurm arguments passed to the `sbatch` script and `srun`.
 - **cache_docker_images_locally**: Specifies whether CloudAI should cache remote Docker images locally during installation. If set to `true`, CloudAI will cache the Docker images, enabling local access without needing to download them each time a test is run. This approach saves network bandwidth but requires more disk capacity. If set to `false`, CloudAI will allow Slurm to download the Docker images as needed when they are not cached locally by Slurm.
 - **global_env_vars**: Lists all global environment variables that will be applied globally whenever tests are run.
 
+## Describing a System for RunAI Scheduler
+When using RunAI as the scheduler, you need to specify additional fields in the system schema TOML file. Below is the list of required fields and how to set them:
+
+```toml
+name = "runai-cluster"
+scheduler = "runai"
+
+install_path = "./install"
+output_path = "./results"
+
+base_url = "http://runai.example.com"       # The URL of your RunAI system, typically the same as used for the web interface.
+user_email = "your_email"              # The email address used to log into the RunAI system.
+app_id = "your_app_id"                      # Obtained by creating an application in the RunAI web interface.
+app_secret = "your_app_secret"              # Obtained together with the app_id.
+project_id = "your_project_id"              # Project ID assigned or created in the RunAI system (usually an integer).
+cluster_id = "your_cluster_id"              # Cluster ID in UUID format (e.g., a69928cc-ccaa-48be-bda9-482440f4d855).
+```
+* After logging into the RunAI web interface, navigate to Access → Applications and create a new application to obtain app_id and app_secret.
+* Use your assigned project and cluster IDs. Contact your administrator if they are not available.
+* All other fields follow the same semantics as in the Slurm system schema (e.g., install_path, output_path).
+
 ## Describing a Test Scenario in the Test Scenario Schema
 A test scenario is a set of tests with specific dependencies between them. A test scenario is described in a TOML schema file. This is an example of a test scenario file:
 ```toml
