-### exec
-
-Runs a secondary process in the given container.
-
-* *Options*
-  * *`--process <PATH>`* Override `process.json` with an alternative path.  The path may not support seeking (e.g. `/dev/fd/3`).
-* *Arguments*
-  * *`<ID>`* The container ID to join.
-* *Standard streams:* The runtime must attach its standard streams directly to the application process without inspection.
-* *Exit code:* The runtime must exit with the application process's exit code.
-
-If the main application (launched by `start`) dies, all other processes in its container will be killed [TODO: link to lifecycle docs explaining this].
-
-Example:
-```sh
-# in a directory with a process.json that echos "goodbye" and exits 43
-$ funC exec hello-1
-goodbye
-$ echo $?
-43
-```
-
-### pause
-
-Pause all processes in a container.
-
-* *Options*
-  * *`--wait`* Block until the process is completely paused.
-  Otherwise return immediately after initiating the pause, which may happen before the pause is complete.
-* *Arguments*
-  * *`<ID>`* The container ID to join.
-* *Exit code:* 0 on success, non-zero on error.
-
-Example:
-```sh
-$ funC pause --wait hello-1
-$ echo $?
-0
-```
-
-### resume
-
-Unpause all processes in a container.
-
-* *Options*
-  * *`--wait`* Block until the process is completely unpaused.
-  Otherwise return immediately after initiating the unpause, which may happen before the unpause is complete.
-* *Arguments*
-  * *`<ID>`* The container ID to join.
-* *Exit code:* 0 on success, non-zero on error.
-
-Example:
-```sh
-$ funC resume hello-1
-$ echo $?
-0
-```
-
-### signal
-
-Sends a signal to the container.
-
-* *Options*
-  * *`--signal <SIGNAL>`* The signal to send.
-    This must be one of the valid POSIX signals, although runtimes on non-POSIX systems must translate the POSIX name to their platorm's analogous signal.
-    Defaults to TERM.
-* *Arguments*
-  * *`<ID>`* The container ID to join.
-* *Exit code:* 0 on success, non-zero on error.
-  A 0 exit status does not imply the process has exited (as it may have caught the signal).
-
-Example:
-```sh
-$ funC signal --signal KILL hello-1
-$ echo $?
-0
-```
