  -This enables you to import these attributes the same way you import the contributors list and use these attributes.
  -
  -Here is an example:
  +You can import and use these attributes in the same way as you import the contributors list.
  +For example:
   
   .feedback.adoc
   [source,asciidoc,indent=0]
  
positive.code: 
  include::../_feedback.adoc[]
  
  This tasks crawls through all Asciidoctor source files and extracts a list of contributors.
  This list is then rendered as AsciiDoc images of the contributor's gravatar picture.
  
  The extracted lists are stored in `{targetDir}/contributors/{filename}` to be easily included in your documents.
  
  Best way to use this feature is to create a `feedback.adoc` file which might look like this:
  
  .feedback.adoc
  [source,asciidoc,indent=0]
  
negative.code: 
      include::{targetDir}/contributors/{filename}[] // <4>
  ----
  .Key:
  <1> Do not show this section when docs are rendered as PDF.
  <2> Create an **Improve This Doc** button which links to your GitHub sources.
  <3> Create a **Create an Issue** button which links to your issue tracker.
  <4> Include the list of contributors created by this task.
  
  _(The task automatically adds the estimated reading time to the list of contributors.)_
  
  == File Attributes
  
  This task also exports some GitHub file attributes.
  The extracted attributes are stored in `{targetDir}/fileattribs/{filename}`.
