-Hook paths are absolute and are executed from the host's filesystem in the [runtime namespace][runtime-namespace].
+The hook structure supports the following fields:
+
+* **`path`** (string, REQUIRED) is absolute path of the command to run from the host's filesystem in the [runtime namespace][runtime-namespace]
+* **`args`** (array of string, OPTIONAL) holds command line arguments, including the command as Args[0]
+* **`env`** (array of string, OPTIONAL) is the environment of the process
