+# Protected Branches
+
+[Permissions](../permissions.md) in GitLab are fundamentally defined around the
+idea of having read or write permission to the repository and branches. To
+prevent people from messing with history or pushing code without review, we've
+created protected branches.
+
+By default, a protected branch does four simple things:
+
+- it prevents its creation, if not already created, from everybody except users
+  with Master permission
+- it prevents pushes from everybody except users with Master permission
+- it prevents **anyone** from force pushing to the branch
+- it prevents **anyone** from deleting the branch
+
+See the [Changelog](#changelog) section for changes over time.
+
+## Configuring protected branches
+
+To protect a branch, you need to have at least Master permission level. Note
+that the `master` branch is protected by default.
+
+1. Navigate to the main page of the project.
+1. In the upper right corner, click the settings wheel and select **Protected branches**.
+
+    ![Project settings list](img/project_settings_list.png)
+
+1. From the **Branch** dropdown menu, select the branch you want to protect and
+   click **Protect**. In the screenshot below, we chose the `develop` branch.
+
+    ![Choose protected branch](img/protected_branches_choose_branch.png)
+
+1. Once done, the protected branch will appear in the "Already protected" list.
+
+    ![Protected branches list](img/protected_branches_list.png)
+
+
+Since GitLab 8.10, we added another layer of branch protection which provides
+more granular management of protected branches. You can now choose the option
+"Developers can merge" so that Developer users can merge a merge request but
+not directly push. In that case, your branches are protected from direct pushes,
+yet Developers don't need elevated permissions or wait for someone with a higher
+permission level to press merge.
+
+You can set this option while creating the protected branch or after its
+creation.
+
+## Wildcard protected branches
+
+>**Note:**
+This feature was [introduced][ce-4665] in GitLab 8.10.
+
+You can specify a wildcard protected branch, which will protect all branches
+matching the wildcard. For example:
+
+| Wildcard Protected Branch | Matching Branches                                      |
+|---------------------------+--------------------------------------------------------|
+| `*-stable`                | `production-stable`, `staging-stable`                  |
+| `production/*`            | `production/app-server`, `production/load-balancer`    |
+| `*gitlab*`                | `gitlab`, `gitlab/staging`, `master/gitlab/production` |
+
+Protected branch settings (like "Developers can push") apply to all matching
+branches.
+
+Two different wildcards can potentially match the same branch. For example,
+`*-stable` and `production-*` would both match a `production-stable` branch.
+In that case, if _any_ of these protected branches have a setting like
+"Allowed to push", then `production-stable` will also inherit this setting.
+
+If you click on a protected branch's name that is created using a wildcard,
+you will be presented with a list of all matching branches:
+
+![Protected branch matches](img/protected_branches_matches.png)
+
+## Restrict the creation of protected branches
+
+Creating a protected branch or a list of protected branches using the wildcard
+feature, not only you are restricting pushes to those branches, but also their
+creation if not already created.
+
+## Error messages when pushing to a protected branch
+
+A user with insufficient permissions will be presented with an error when
+creating or pushing to a branch that's prohibited, either through GitLab's UI:
+
+![Protected branch error GitLab UI](img/protected_branches_error_ui.png)
+
+or using Git from their terminal:
+
+```bash
+remote: GitLab: You are not allowed to push code to protected branches on this project.
+To https://gitlab.example.com/thedude/bowling.git
+ ! [remote rejected] staging-stable -> staging-stable (pre-receive hook declined)
+error: failed to push some refs to 'https://gitlab.example.com/thedude/bowling.git'
+```

-# Protected Branches
-
-Permissions in GitLab are fundamentally defined around the idea of having read or write permission to the repository and branches.
-
-To prevent people from messing with history or pushing code without review, we've created protected branches.
-
-A protected branch does three simple things:
-
-* it prevents pushes from everybody except users with Master permission
-* it prevents anyone from force pushing to the branch
-* it prevents anyone from deleting the branch
-
-You can make any branch a protected branch. GitLab makes the master branch a protected branch by default.
-
-To protect a branch, user needs to have at least a Master permission level, see [permissions document](../user/permissions.md).
-
-![protected branches page](protected_branches/protected_branches1.png)
-
-Navigate to project settings page and select `protected branches`. From the `Branch` dropdown menu select the branch you want to protect.
-
-Some workflows, like [GitLab workflow](gitlab_flow.md), require all users with write access to submit a Merge request in order to get the code into a protected branch.
-
-Since Masters and Owners can already push to protected branches, that means Developers cannot push to protected branch and need to submit a Merge request.
-
-However, there are workflows where that is not needed and only protecting from force pushes and branch removal is useful.
-
-For those workflows, you can allow everyone with write access to push to a protected branch by selecting `Developers can push` check box.
-
-On already protected branches you can also allow developers to push to the repository by selecting the `Developers can push` check box.

-## Wildcard Protected Branches
-
->**Note:**
-This feature was added in GitLab 8.10.
-
-1. You can specify a wildcard protected branch, which will protect all branches matching the wildcard. For example:
-
-    | Wildcard Protected Branch | Matching Branches                                      |
-    |---------------------------+--------------------------------------------------------|
-    | `*-stable`                | `production-stable`, `staging-stable`                  |
-    | `production/*`            | `production/app-server`, `production/load-balancer`    |
-    | `*gitlab*`                | `gitlab`, `gitlab/staging`, `master/gitlab/production` |
-
-1. Protected branch settings (like "Developers Can Push") apply to all matching branches.
-
-1. Two different wildcards can potentially match the same branch. For example, `*-stable` and `production-*` would both match a `production-stable` branch.
-   >**Note:**
-   If _any_ of these protected branches have "Developers Can Push" set to true, then `production-stable` has it set to true.
-
-1. If you click on a protected branch's name, you will be presented with a list of all matching branches:
