## Reviewer roulette
|
||
|
|
||
|
Changes that require review have been detected! A merge request is normally
|
||
|
reviewed by both a reviewer and a maintainer in its primary category (e.g.
|
||
|
~frontend or ~backend), and by a maintainer in all other categories.
|
||
|
MARKDOWN
|
||
|
|
||
|
CATEGORY_TABLE_HEADER = <<MARKDOWN
|
||
|
|
||
|
To spread load more evenly across eligible reviewers, Danger has randomly picked
|
||
|
a candidate for each review slot. Feel free to override this selection if you
|
||
|
think someone else would be better-suited, or the chosen person is unavailable.
|
||
|
|
||
|
Once you've decided who will review this merge request, mention them as you
|
||
|
normally would! Danger does not (yet?) automatically notify them for you.

These files couldn't be categorised, so Danger was unable to suggest a reviewer.

Please consider creating a merge request to

[add support](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/lib/gitlab/danger/helper.rb)

for them.
