 1. Create `gron.d` directory
 2. Create job config in `gron.d/job1.conf` ([TOML](https://en.wikipedia.org/wiki/TOML) format):
     ```toml
-    Cron                   = "* * * * *"                # cron instructions
+    Type                   = "cmd"        # command execution
-    Command                = "echo Hello"               # command to execute

+
+    Command                = "echo Hello" # command to execute
+    ```
+
+    SQL job:
+    ```toml
+    Type                   = "sql"                            # sql execution

+    SqlText                = "CALL procedure"                 # command to execute

     Description            = "print Hello every minute" # job description
     NumberOfRestartAttemts = 3                          # number of restart attemts
     RestartSec             = 5                          # the time to sleep before restarting a job (seconds)
