@@ -64,6 +64,49 @@ Merge requests may still be merged into master during this period,
 but they will go into the _next_ release, unless they are manually cherry-picked into the stable branch.
 By freezing the stable branches 2 weeks prior to a release, we reduce the risk of a last minute merge request potentially breaking things.
 
+### Between the 1st and the 7th
+
+These types of merge requests need special consideration:
+
+* **Large features**: a large feature is one that is highlighted in the kick-off
+  and the release blogpost; typically this will have its own channel in Slack
+  and a dedicated team with front-end, back-end, and UX.
+* **Small features**: any other feature request.
+
+**Large features** must be with a maintainer **by the 1st**. It's OK if they
+aren't completely done, but this allows the maintainer enough time to make the
+decision about whether this can make it in before the freeze. If the maintainer
+doesn't think it will make it, they should inform the developers working on it
+and the Product Manager responsible for the feature.
+
+**Small features** must be with a reviewer (not necessarily maintainer) **by the
+3rd**.
+
+Most merge requests from the community do not have a specific release
+target. However, if one does and falls into either of the above categories, it's
+the reviewer's responsibility to manage the above communication and assignment
+on behalf of the community member.
+
+### On the 7th
+
+Merge requests should still be complete, following the
+[definition of done][done]. The single exception is documentation, and this can
+only be left until after the freeze if:
+
+* There is a follow-up issue to add documentation.
+* It is assigned to the person writing documentation for this feature, and they
+  are aware of it.
+* It is in the correct milestone, with the ~Deliverable label.
+
+All Community Edition merge requests from GitLab team members merged on the
+freeze date (the 7th) should have a corresponding Enterprise Edition merge
+request, even if there are no conflicts. This is to reduce the size of the
+subsequent EE merge, as we often merge a lot to CE on the release date. For more
+information, see
+[limit conflicts with EE when developing on CE][limit_ee_conflicts].
+
+### Between the 7th and the 22nd
+
 Once the stable branch is frozen, only fixes for regressions (bugs introduced in that same release)
 and security issues will be cherry-picked into the stable branch.
 Any merge requests cherry-picked into the stable branch for a previous release will also be picked into the latest stable branch.

+# GitHub import

+>**Note:**

+>  - [Introduced][ce-10308] in GitLab 9.1.
+>  - You need a personal access token in order to retrieve and import GitHub 
+>    projects. You can get it from: https://github.com/settings/tokens
+>  - You also need to pass an username as the second argument to the rake task
+>    which will become the owner of the project.
+
+To import a project from the list of your GitHub projects available:
+
+```bash
+# Omnibus installations
+sudo gitlab-rake import:github[access_token,root,foo/bar]
+
+# Installations from source
+bundle exec rake import:github[access_token,root,foo/bar] RAILS_ENV=production
+```
+
+In this case, `access_token` is your GitHub personal access token, `root`
+is your GitLab username, and  `foo/bar` is the new GitLab namespace/project that 
+will get created from your GitHub project. Subgroups are also possible: `foo/foo/bar`.
+
+
+To import a specific GitHub project (named `foo/github_repo` here):
+
+```bash
+# Omnibus installations
+sudo gitlab-rake import:github[access_token,root,foo/bar,foo/github_repo]
+
+# Installations from source
+bundle exec rake import:github[access_token,root,foo/bar,foo/github_repo] RAILS_ENV=production

+
+To enable Microsoft Teams integration you must create an incoming webhook integration on Microsoft Teams by following the steps described in this [document](https://msdn.microsoft.com/en-us/microsoft-teams/connectors)
+
+## On GitLab
+
+After you set up Microsoft Teams, it's time to set up GitLab.
+
+Navigate to the [Integrations page](project_services.md#accessing-the-project-services)
+and select the **Microsoft Teams Notification** service to configure it.
+There, you will see a checkbox with the following events that can be triggered:
+
+- Push
+- Issue
+- Confidential issue
+- Merge request
+- Note
+- Tag push
+- Pipeline
+- Wiki page
+
+At the end fill in your Microsoft Teams details:
+
+| Field | Description |
+| ----- | ----------- |
+| **Webhook** | The incoming webhook URL which you have to setup on Microsoft Teams. |
+| **Notify only broken pipelines** | If you choose to enable the **Pipeline** event and you want to be only notified about failed pipelines. |
+
+After you are all done, click **Save changes** for the changes to take effect.
