# Command

There are basically two commands you can give to a process: `start` or `stop`. This is the order for the process.

Additionally to these two commands are the commands `restart` which is sending a `stop` followed by a `start` command packed in one command, and `reload` which is the same as if you would update the process config with itself, e.g. in order to update references to another process.

* `start` the process. If the process is already started, this won't have any effect.
* `stop` the process. If the process is already stopped, this won't have any effect.
* `restart` the process. If the process is not running, this won't have any effect.
* `reload` the process. If the process was running, the reloaded process will start automatically.
