Dear Friends at Epic,

Thank you for this awesome UE4 experience!

```auto

I was wondering if a short document could be written clearly explaining how to use the UE_LOG system

I'd imagine it would be added to this section:
https://rocket.unrealengine.com/docs/ue4/INT/GettingStarted/Programming/index.html

I've been sorting through the shootergame trying to find the example uses, but I have not put it all together in my head yet.

Wonderful forum member Wraiyth told me this info:

"The equivalent of `log is UE_LOG

In each file, you define a log category, something like
DECLARE_LOG_CATEGORY_STATIC( LogMyLogCategory, Log, All );

Then you use it:
UE_LOG( LogMyLogCategory, Log, TEXT("This is a log message!" ) );"

But I am as yet not able to sort out how this is organized, and I got compile errors with my attempts so far.

**A clear simple document on how I can give myself in-game feedback would be lovely,** as I am mostly running my game from the right click menu not the editor

:)
```

This is already on our radar and we have a task in the bug tracker to add this documentation. It’s coming as soon as priorities allow. 🙂

I would love this as well, I’ve found some examples but they are incomplete.
