+### Incremental build trace update
+
+Using this method you need to send trace content as a request body. You also need to provide the `Content-Range` header
+with a range of sent trace part. Note that you need to send parts in the proper order, so the begining of the part
+must start just after the end of the previous part. If you provide the wrong part, then GitLab CI API will return `416
+Range Not Satisfiable` response with a header `Range: 0-X`, where `X` is the current trace length.
+
+For example, if you receive `Range: 0-11` in the response, then your next part must contain a `Content-Range: 11-...`
+header and a trace part covered by this range.
+
+For a valid update API will return `202` response with:
+* `Build-Status: {status}` header containing current status of the build,
+* `Range: 0-{length}` header with the current trace length.

+## Gitlab Runner
+
+We strongly advise against installing GitLab Runner on the same machine you plan
+to install GitLab on. Depending on how you decide to configure GitLab Runner and
+what tools you use to exercise your application in the CI environment, GitLab
+Runner can consume significant amount of available memory.

+Memory consumption calculations, that are available above, will not be valid if
+you decide to run GitLab Runner and the GitLab Rails application on the same
+machine.
+
+It is also not safe to install everything on a single machine, because of the
+[security reasons] - especially when you plan to use shell executor with GitLab
+Runner.
+
+We recommend using a separate machine for each GitLab Runner, if you plan to
+use the CI features.

+# Cherry-pick changes
+
+_**Note:** This feature was [introduced][ce-3514] in GitLab 8.7._
+
+---
+
+GitLab implements Git's powerful feature to [cherry-pick any commit][git-cherry-pick]
+with introducing a **Cherry-pick** button in Merge Requests and commit details.
+
+## Cherry-picking a Merge Request
+
+After the Merge Request has been merged, a **Cherry-pick** button will be available
+to cherry-pick the changes introduced by that Merge Request:
+
+![Cherry-pick Merge Request](img/cherry_pick_changes_mr.png)
+
+---
+
+You can cherry-pick the changes directly into the selected branch or you can opt to
+create a new Merge Request with the cherry-pick changes:
+
+![Cherry-pick Merge Request modal](img/cherry_pick_changes_mr_modal.png)
+
+## Cherry-picking a Commit
+
+You can cherry-pick a Commit from the Commit details page:
+
+![Cherry-pick commit](img/cherry_pick_changes_commit.png)
+
+---
+
+Similar to cherry-picking a Merge Request, you can opt to cherry-pick the changes
+directly into the target branch or create a new Merge Request to cherry-pick the
+changes:
+
+![Cherry-pick commit modal](img/cherry_pick_changes_commit_modal.png)
+
+---
+
+Please note that when cherry-picking merge commits, the mainline will always be the
+first parent. If you want to use a different mainline then you need to do that
+from the command line.
+
+Here is a quick example to cherry-pick a merge commit using the second parent as the
+mainline:
+
+```bash
+git cherry-pick -m 2 7a39eb0
+```
+
