+## Note on release description
+The easiest way of getting a good release description is to defer its generation to the GitHub. So if you completely leave out the `<description>` configuration
+parameter, then GitHub will generate a meaningful description for you. Otherwise, if description _is_ supplied, it will be prepended to one generated by GitHub.

 ## Note on the GitHub API endpoints
 The endpoint for GitHub API is inferred from `<scm>` connection string. When missing, it by default would use the public endpoint at https://api.github.com.
 If you want to upload to a GitHub enterprise instance, then a respective `<scm>` connection string must be specified.
