+### What is JSON/How do I change my configuration?
+JSON is a text format that allows structured data storage in a plain-text format.  
+IW4MAdmin uses this format to store configuration data.  
+Because the format is very specific, it is recommended to run any configuration changes through a [JSON validator/formatter](https://jsonformatter.curiousconcept.com/) before starting IW4MAdmin.  
+If you receive a message like below when starting IW4MAdmin, it is likely you made a change that resulted in an invalid JSON format

+This error message displays the file as well as the line number the format error occurred on.  
+**This will need to be addressed before IW4MAdmin can start.**

+### I'm running an IW4x server and I see duplicated messages from IW4MAdmin
+This is an IW4x bug that causes out of band packets to be dropped or processed multiple times.  
+There is an open PR to resolve this https://github.com/XLabsProject/iw4x-client/pull/29, but until that is merged there is no work around short of compiling IW4x yourself.
