+The configuration of `welcome` can either be stored in `~/.welcome` or in `$XDG_CONFIG_HOME/welcome` (which defaults to `~/.config/welcome`). Please create this directory and place all files from the following steps into it.

 #### Warners
 
 Warners are the second kind of information provider. The difference to summarizers is that a warner does not have to output anything. They are useful for information that is only relevant in specific situations (for example when a package update is available like in the screenshot above).
