+Backport of PR #7302 to branch 5.x failed
+
+https://github.com/elastic/kibana/pull/7302
+
+
+- 7 patches failed to apply
+- 20 patches were applied successfully
+
+-------------------------------------
+
+At this point, you need to manually resolve these conflicts on your machine and
+push the changes back up to this upstream branch so the PR is updated with your
+changes. The following instructions and scripts should help with that.
+
+All of the provided scripts assume that the remote "upstream" is where the
+backport branch exists and that your local branch has the exact same name as
+the upstream branch.
+
+First, check out this branch locally:
+
+  git fetch upstream jasper/backport/7302/5.x
+  git checkout jasper/backport/7302/5.x
+
+Now, just follow one of these two paths:
+
+
+1. GUIDED BACKPORT
+
+You should do the guided backport if you want to apply the backported changes
+while resolving the conflicts on each commit. For most cases, this is what you
+want to do.
+
+The following script will rebase the commits that need to be backported onto
+a new temporary branch. Resolve any conflicts as you normally would during a
+rebase. Do not remove these backport-*.rej files, and feel free to add
+additional commits if that's necessary:
+
+    sh backport-guided-begin.rej
+
+Once the conficts are resolved and the rebase is completed, the following
+script will update the local backport branch with the changes, remove the
+temporary branch that was created, remove the remnants of this backport commit
+and squash the newly resolved commits (and any others you may have added) into
+a single backport commit with the proper commit message:
+
+    sh backport-guided-finish.rej
+
+At this point, you should be on the local backport branch, and it should be
+exactly 1 commit ahead of the intended target. The commit message should be
+very similar if not identical to the PR itself, and the changeset should
+include all of the changes you intended to backport and none of these
+backport-*.rej files.
+
+Now just replace the contents of the pull request with your local changes:
+
+    git push -f upstream jasper/backport/7302/5.x
+
+
+2. ALMOST COMPLETELY MANUAL
+
+You should do this option if there are just so many conflicts that it's easier
+to rebuild the entire changeset from scratch. You'll still work on the local
+backport branch which should be up to date with the intended target.
+
+Feel free to add as many commits as you'd like and don't worry about fancy
+commit messages - we're just going to squash them down and replace the message
+when you're finished.
+
+Once the changes are committed on your local backport branch, the following
+script will remove the remnants of this backport commit and squash the newly
+created commits into a single backport commit with the proper commit message.
+
+    sh backport-wrangle-into-commit.rej
+
+At this point, you should be on the local backport branch, and it should be
+exactly 1 commit ahead of the intended target. The commit message should be
+very similar if not identical to the PR itself, and the changeset should
+include all of the changes you intended to backport and none of these
+backport-*.rej files.
+
+Now just replace the contents of the pull request with your local changes:
+
+    git push -f upstream jasper/backport/7302/5.x
