Hi All,

I'm following the guide to stash first event, but I'm getting an error message in the command line when verifying logstash installation. I can CD to logstash directory but it's when I specify configuration from command line using -e flag where it fails.

I'm typing the following into command line:

````auto

This is the error message I get. 
```C:\Elastic Search\logstash-7.12.1\bin>logstash -e 'input { stdin { } } output { stdout {} }'

I see the issue  
ERROR: Unknown command '{'

what am I suppose to do though, as this is exactly what is pasted on their guide. I did a copy and paste.

Do we not close the curly braces?

Use double quotes, not single quotes

```
logstash.bat -e "input {stdin {} } output { stdout{}}"
```
