+# Geo nodes admin area **[PREMIUM ONLY]**
+
+For more information about setting up GitLab Geo, read the
+[Geo documentation](https://docs.gitlab.com/ee/administration/geo/replication/index.html).
+
+When you're done, you can navigate to **Admin area > Geo** (`/admin/geo/nodes`).
+
+## Common settings
+
+All Geo nodes have the following settings:
+
+| Setting | Description |
+| --------| ----------- |
+| Primary | This marks a Geo Node as primary. There can be only one primary, make sure that you first add the primary node and then all the others. |
+| URL     | The instance's full URL, in the same way it is configured in  `/etc/gitlab/gitlab.rb` (Omnibus GitLab installations) or `gitlab.yml` (source based installations). |
+
+The node you're reading from is indicated with a green `Current node` label, and
+the primary is given a blue `Primary` label. Remember that you can only make
+changes on the primary!
+
+## Secondary node settings
+
+Secondaries have a number of additional settings available:
+
+| Setting                   | Description |
+|---------------------------|-------------|
+ Selective synchronization | Enable Geo [selective sync](https://docs.gitlab.com/ee/administration/geo/replication/configuration.html#selective-synchronization) for this **secondary** node. |
+| Repository sync capacity  | Number of concurrent requests this **secondary** node will make to the **primary** node when backfilling repositories. |
+| File sync capacity        | Number of concurrent requests this **secondary** node will make to the **primary** node when backfilling files. |
+
+## Geo backfill
+
+Secondaries are notified of changes to repositories and files by the primary,
+and will always attempt to synchronize those changes as quickly as possible.
+
+Backfill is the act of populating the secondary with repositories and files that
+existed *before* the secondary was added to the database. Since there may be
+extremely large numbers of repositories and files, it's infeasible to attempt to
+download them all at once, so GitLab places an upper limit on the concurrency of
+these operations.
+
+How long the backfill takes is a function of the maximum concurrency, but higher
+values place more strain on the primary node. From [GitLab 10.2](https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/3107),
+the limits are configurable - if your primary node has lots of surplus capacity,
+you can increase the values to complete backfill in a shorter time. If it's
+under heavy load and backfill is reducing its availability for normal requests,
+you can decrease them.
+
+## Using a different URL for synchronization
+
+The **primary** node's Internal URL is used by **secondary** nodes to contact it
+(to sync repositories, for example). The name Internal URL distinguishes it from
+[External URL](https://docs.gitlab.com/omnibus/settings/configuration.html#configuring-the-external-url-for-gitlab)
+which is used by users. Internal URL does not need to be a private address.
+
+Internal URL defaults to External URL, but you can customize it under
+**Admin area > Geo Nodes**.

+# Activate all GitLab Enterprise Edition functionality with a license **[STARTER ONLY]**
+
+To activate all GitLab Enterprise Edition (EE) functionality, you need to upload
+a license. Once you've received your license from GitLab Inc., you can upload it
+by **signing into your GitLab instance as an admin**.
+
+The license has the form of a base64 encoded ASCII text with a `.gitlab-license`
+extension and can be obtained when you [purchase one][pricing] or when you sign
+up for a [free trial].
+
+NOTE: **Note:**
+As of GitLab Enterprise Edition 9.4.0, a newly-installed instance without an
+uploaded license will only have the Core features active. A trial license will
+activate all Ultimate features, but after
+[the trial expires](#what-happens-when-your-license-expires), some functionality
+will be locked.
+
+## Uploading your license
+
+The very first time you visit your GitLab EE installation signed in as an admin,
+you should see a note urging you to upload a license with a link that takes you
+straight to the License admin area.
+
+Otherwise, you can:
+
+1. Navigate manually to the **Admin Area** by clicking the wrench icon in the menu bar.
+
+    ![Admin area icon](img/admin_wrench.png)
+
+1. And then going to the **License** tab and click on **Upload New License**.
+
+    ![License admin area](img/license_admin_area.png)
+
+1. If you've received a `.gitlab-license` file, you should have already downloaded
+   it in your local machine. You can then upload it directly by choosing the
+   license file and clicking the **Upload license** button. In the image below,
+   you can see that the selected license file is named `GitLab.gitlab-license`.
+
+    ![Upload license](img/license_upload.png)
+
+    If you've received your license as plain text, you need to select the
+    "Enter license key" option, copy the license, paste it into the "License key"
+    field and click **Upload license**.
+
+---
+
+Once the license is uploaded, all GitLab Enterprise Edition functionality
+will be active until the end of the license period. When that period ends, the
+instance will [fall back](#what-happens-when-your-license-expires) to Core-only
+functionality.
+
+You can review the license details at any time in the License section of the
+Admin Area.
+
+![License details](img/license_details.png)
+
+## Notification before the license expires
+
+One month before the license expires, a message informing when the expiration
+is due to, will start appearing to GitLab admins. Make sure that you update your
+license, otherwise you will miss all the paid features if it expires.
+
+## What happens when your license expires
+
+In case your license expires, GitLab will lock down some features like Git pushes,
+issue creation, etc., and a message to inform of the expired license will be
+presented to all admins.
+
+In order to get back all the previous functionality, a new license must be uploaded.
+To fall back to having only the Core features active, you'll need to delete the
+expired license(s).
+
+## License history
+
+It's possible to upload and view more than one license,
+but only the latest license will be used as the active license.

+# Account and limit settings
+
+## Repository size limit **[STARTER]**
+
+> [Introduced][ee-740] in [GitLab Enterprise Edition 8.12][ee-8.12].
+
+Repositories within your GitLab instance can grow quickly, especially if you are
+using LFS. Their size can grow exponentially and eat up your storage device quite
+fast.
+
+In order to avoid this from happening, you can set a hard limit for your
+repositories' size. This limit can be set globally, per group, or per project,
+with per project limits taking the highest priority.
+
+There are numerous cases where you'll need to set up a limit for repository size.
+For instance, consider the following workflow:
+
+1. Your team develops apps which demand large files to be stored in
+   the application repository.
+1. Although you have enabled [Git LFS](../../../workflow/lfs/manage_large_binaries_with_git_lfs.html#git-lfs)
+   to your project, your storage has grown significantly.
+1. Before you blow your storage limit up, you set up a limit of 10 GB
+   per repository.
+
+### How it works
+
+Only a GitLab administrator can set those limits. Setting the limit to `0` means
+there are no restrictions.
+
+These settings can be found within:
+
+- Each project's settings.
+- A group's settings.
+- The **Size limit per repository (MB)** field in the **Account and limit** section of a GitLab instance's
+  settings by navigating to either:
+  - **Admin Area > Settings > General**.
+  - The path `/admin/application_settings`.
+
+The very first push of a new project cannot be checked for size as of now, so
+the first push will allow you to upload more than the limit dictates, but every
+subsequent push will be denied. LFS objects, however, can be checked on first
+push and **will** be rejected if the sum of their sizes exceeds the maximum
+allowed repository size.
+
+For more manually purging the files, read the docs on
+[reducing the repository size using Git][repo-size].
+
+> **Note:**
+> For GitLab.com, the repository size limit is 10 GB.

+# Instance template repository **[PREMIUM ONLY]**
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ee/issues/5986) in
+> [GitLab Premium](https://about.gitlab.com/pricing) 11.3.
+
+## Overview
+
+In hosted systems, enterprises often have a need to share their own templates
+across teams. This feature allows an administrator to pick a project to be the
+instance-wide collection of file templates. These templates are then exposed to
+all users [via the web editor](../../project/repository/web_editor.md#template-dropdowns)
+while the project remains secure.
+
+## Configuration
+
+As an administrator, navigate to **Admin area > Settings > Templates** and
+select the project to serve as the custom template repository.
+
+![File templates in the admin area](img/file_template_admin_area.png)
+
+Once a project has been selected, you can add custom templates to the repository,
+and they will appear in the appropriate places in the
+[frontend](../../project/repository/web_editor.md#template-dropdowns) and
+[API](../../../api/settings.md).
+
+Templates must be added to a specific subdirectory in the repository,
+corresponding to the kind of template. The following types of custom templates
+are supported:
+
+| Type              | Directory     | Extension     |
+| :---------------: | :-----------: | :-----------: |
+| `Dockerfile`      | `Dockerfile`  | `.dockerfile` |
+| `.gitignore`      | `gitignore`   | `.gitignore`  |
+| `.gitlab-ci.yml`  | `gitlab-ci`   | `.yml`        |
+| `LICENSE`         | `LICENSE`     | `.txt`        |
+
+Each template must go in its respective subdirectory, have the correct
+extension and not be empty. So, the hierarchy should look like this:
+
+```text
+|-- README.md
+|-- Dockerfile
+    |-- custom_dockerfile.dockerfile
+    |-- another_dockerfile.dockerfile
+|-- gitignore
+    |-- custom_gitignore.gitignore
+    |-- another_gitignore.gitignore
+|-- gitlab-ci
+    |-- custom_gitlab-ci.yml
+    |-- another_gitlab-ci.yml
+|-- LICENSE
+    |-- custom_license.txt
+    |-- another_license.txt
+```
+
+Once this is established, the list of custom templates will be included when
+creating a new file and the template type is selected. These will appear at the
+top of the list.
+
+![Custom template dropdown menu](img/file_template_user_dropdown.png)
+
+If this feature is disabled or no templates are present, there will be
+no "Custom" section in the selection dropdown.
