-**`process`** (object, OPTIONAL) specifies the container process.
+**`process`** (object, OPTIONAL) specifies a process to run inside the container.
   This property is REQUIRED when [`start`](runtime.md#start) is called.
 
-* **`terminal`** (bool, OPTIONAL) specifies whether a terminal is attached to that process, defaults to false.
-  As an example, if set to true on Linux a pseudoterminal pair is allocated for the container process and the pseudoterminal slave is duplicated on the container process's [standard streams][stdin.3].

   This specification extends the IEEE standard in that at least one entry is REQUIRED, and that entry is used with the same semantics as `execvp`'s *file*.
-* **`capabilities`** (object, OPTIONAL) is an object containing arrays that specifies the sets of capabilities for the process(es) inside the container. Valid values are platform-specific. For example, valid values for Linux are defined in the [capabilities(7)][capabilities.7] man page, such as `CAP_CHOWN`. Any value which cannot be mapped to a relevant kernel interface MUST cause an error.

   capabilities contains the following properties:
