-### Default Directory Exclusions
-
-By default, the reports from directory names, that match the following regular expressions, are excluded:
-
-- `third_party$`
-- `examples$`
-- `Godeps$`
-- `builtin$`
-
-This option has been defined when Go modules was not existed and when the golangci-lint core was different, this is not something we still recommend.
-
-At some point, we will remove all those obsolete exclusions, but as it's a breaking changes it will only happen inside a major version.

-So we recommend setting `issues.exclude-dirs-use-default` to `false`.
