+Some LDAP servers, depending on their configurations, can return uppercase usernames. This can lead to several confusing issues like, for example, creating links or namespaces with uppercase names.

+Legacy Storage is the storage behavior prior to version 10.0. For historical
+reasons, GitLab replicated the same mapping structure from the projects URLs:
 
- * Project's repository: `#{namespace}/#{project_name}.git`
- * Project's wiki: `#{namespace}/#{project_name}.wiki.git`
+* Project's repository: `#{namespace}/#{project_name}.git`

 On the other hand this has some drawbacks:
 
-Storage location will concentrate huge amount of top-level namespaces. The impact can be reduced by the introduction of [multiple storage paths][storage-paths].

-Last, for GitLab Geo, this storage type means we have to synchronize the disk state, replicate renames in the correct

+For GitLab Geo in particular: Geo does work with legacy storage, but in some
+edge cases due to race conditions it can lead to errors when a project is
+renamed multiple times in short succession, or a project is deleted and

 ## Hashed Storage

-a hash, based on the project's ID.

+### Path segments
+
+Files are stored at multiple locations and use different path schemes.

+```
+
+The `RecordsUploads::Concern` concern will create an `Upload` entry for every file stored by a `GitlabUploader` persisting the dynamic parts of the path using
+`GitlabUploader#dynamic_path`. You may then use the `Upload#build_uploader` method to manipulate the file.
+
+## Object Storage
+
+By including the `ObjectStorage::Concern` in the `GitlabUploader` derived class, you may enable the object storage for this uploader. To enable the object storage
+in your uploader, you need to either 1) include `RecordsUpload::Concern` and prepend `ObjectStorage::Extension::RecordsUploads` or 2) mount the uploader and create a new field named `<mount>_store`.
+
+The `CarrierWave::Uploader#store_dir` is overriden to
+
+ - `GitlabUploader.base_dir` + `GitlabUploader.dynamic_segment` when the store is LOCAL
+ - `GitlabUploader.dynamic_segment` when the store is REMOTE (the bucket name is used to namespace)
+
+### Using `ObjectStorage::Extension::RecordsUploads`
+
+> Note: this concern will automatically include `RecordsUploads::Concern` if not already included.
+
+The `ObjectStorage::Concern` uploader will search for the matching `Upload` to select the correct object store. The `Upload` is mapped using `#store_dirs + identifier` for each store (LOCAL/REMOTE).
+
+```ruby
+class SongUploader < GitlabUploader
+  include RecordsUploads::Concern
+  include ObjectStorage::Concern
+  prepend ObjectStorage::Extension::RecordsUploads
+
+  ...
+end
+
+class Thing < ActiveRecord::Base
+  mount :theme, SongUploader # we have a great theme song!
+
+  ...
+end
+```
+
+### Using a mounted uploader
+
+The `ObjectStorage::Concern` will query the `model.<mount>_store` attribute to select the correct object store.
+This column must be present in the model schema.
+
+```ruby
+class SongUploader < GitlabUploader
+  include ObjectStorage::Concern
+
+  ...
+end
+
+class Thing < ActiveRecord::Base
+  attr_reader :theme_store # this is an ActiveRecord attribute
+  mount :theme, SongUploader # we have a great theme song!
+
+  def theme_store
+    super || ObjectStorage::Store::LOCAL
+  end
+
+  ...
+end
+```

+# Query Count Limits
+
+Each controller or API endpoint is allowed to execute up to 100 SQL queries. In
+a production environment we'll only log an error in case this threshold is
+exceeded, but in a test environment we'll raise an error instead.
+
+## Solving Failing Tests
+
+When a test fails because it executes more than 100 SQL queries there are two
+solutions to this problem:
+
+1. Reduce the number of SQL queries that are executed.
+2. Whitelist the controller or API endpoint.
+
+You should only resort to whitelisting when an existing controller or endpoint
+is to blame as in this case reducing the number of SQL queries can take a lot of
+effort. Newly added controllers and endpoints are not allowed to execute more
+than 100 SQL queries and no exceptions will be made for this rule. _If_ a large
+number of SQL queries is necessary to perform certain work it's best to have
+this work performed by Sidekiq instead of doing this directly in a web request.
+
+## Whitelisting
+
+In the event that you _have_ to whitelist a controller you'll first need to
+create an issue. This issue should (preferably in the title) mention the
+controller or endpoint and include the appropriate labels (`database`,
+`performance`, and at least a team specific label such as `Discussion`).
+
+Once the issue has been created you can whitelist the code in question. For
+Rails controllers it's best to create a `before_action` hook that runs as early
+as possible. The called method in turn should call
+`Gitlab::QueryLimiting.whitelist('issue URL here')`. For example:
+
+```ruby
+class MyController < ApplicationController
+  before_action :whitelist_query_limiting, only: [:show]
+
+  def index
+    # ...
+  end
+
+  def show
+    # ...
+  end
+
+  def whitelist_query_limiting
+    Gitlab::QueryLimiting.whitelist('https://gitlab.com/gitlab-org/...')
+  end
+end
+```
+
+By using a `before_action` you don't have to modify the controller method in
+question, reducing the likelihood of merge conflicts.
+
+For Grape API endpoints there unfortunately is not a reliable way of running a
+hook before a specific endpoint. This means that you have to add the whitelist
+call directly into the endpoint like so:
+
+```ruby
+get '/projects/:id/foo' do
+  Gitlab::QueryLimiting.whitelist('...')
+
+  # ...
+end
+```

+# From 10.4 to 10.5
+
+Make sure you view this update guide from the tag (version) of GitLab you would
+like to install. In most cases this should be the highest numbered production
+tag (without rc in it). You can select the tag in the version dropdown at the
+top left corner of GitLab (below the menu bar).
+
+If the highest number stable branch is unclear please check the
+[GitLab Blog](https://about.gitlab.com/blog/archives.html) for installation
+guide links by version.
+
+### 1. Stop server
+
+```bash
+sudo service gitlab stop
+```
+
+### 2. Backup
+
+NOTE: If you installed GitLab from source, make sure `rsync` is installed.
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production
+```
+
+### 3. Update Ruby
+
+NOTE: GitLab 9.0 and higher only support Ruby 2.3.x and dropped support for Ruby 2.1.x. Be
+sure to upgrade your interpreter if necessary.
+
+You can check which version you are running with `ruby -v`.
+
+Download and compile Ruby:
+
+```bash
+mkdir /tmp/ruby && cd /tmp/ruby
+curl --remote-name --progress https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.6.tar.gz
+echo '4e6a0f828819e15d274ae58485585fc8b7caace0  ruby-2.3.6.tar.gz' | shasum -c - && tar xzf ruby-2.3.6.tar.gz
+cd ruby-2.3.6
+./configure --disable-install-rdoc
+make
+sudo make install
+```
+
+Install Bundler:
+
+```bash
+sudo gem install bundler --no-ri --no-rdoc
+```
+
+### 4. Update Node
+
+GitLab now runs [webpack](http://webpack.js.org) to compile frontend assets.
+We require a minimum version of node v6.0.0.
+
+You can check which version you are running with `node -v`. If you are running
+a version older than `v6.0.0` you will need to update to a newer version. You
+can find instructions to install from community maintained packages or compile
+from source at the nodejs.org website.
+
+<https://nodejs.org/en/download/>
+
+Since 8.17, GitLab requires the use of yarn `>= v0.17.0` to manage
+JavaScript dependencies.
+
+```bash
+curl --silent --show-error https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
+echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
+sudo apt-get update
+sudo apt-get install yarn
+```
+
+More information can be found on the [yarn website](https://yarnpkg.com/en/docs/install).
+
+### 5. Update Go
+
+NOTE: GitLab 9.2 and higher only supports Go 1.8.3 and dropped support for Go
+1.5.x through 1.7.x. Be sure to upgrade your installation if necessary.
+
+You can check which version you are running with `go version`.
+
+Download and install Go:
+
+```bash
+# Remove former Go installation folder
+sudo rm -rf /usr/local/go
+
+curl --remote-name --progress https://storage.googleapis.com/golang/go1.8.3.linux-amd64.tar.gz
+echo '1862f4c3d3907e59b04a757cfda0ea7aa9ef39274af99a784f5be843c80c6772  go1.8.3.linux-amd64.tar.gz' | shasum -a256 -c - && \

+sudo ln -sf /usr/local/go/bin/{go,godoc,gofmt} /usr/local/bin/
+rm go1.8.3.linux-amd64.tar.gz
+```
+
+### 6. Get latest code
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git fetch --all
+sudo -u git -H git checkout -- db/schema.rb # local changes will be restored automatically
+sudo -u git -H git checkout -- locale
+```
+
+For GitLab Community Edition:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git checkout 10-5-stable
+```
+
+OR
+
+For GitLab Enterprise Edition:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git checkout 10-5-stable-ee
+```
+
+### 7. Update gitlab-shell
+
+```bash
+cd /home/git/gitlab-shell
+
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_SHELL_VERSION)
+sudo -u git -H bin/compile
+```
+
+### 8. Update gitlab-workhorse
+
+Install and compile gitlab-workhorse. GitLab-Workhorse uses
+[GNU Make](https://www.gnu.org/software/make/).
+If you are not using Linux you may have to run `gmake` instead of
+`make` below.
+
+```bash
+cd /home/git/gitlab-workhorse
+
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_WORKHORSE_VERSION)
+sudo -u git -H make
+```
+
+### 9. Update Gitaly
+
+#### New Gitaly configuration options required
+
+In order to function Gitaly needs some additional configuration information. Below we assume you installed Gitaly in `/home/git/gitaly` and GitLab Shell in `/home/git/gitlab-shell`.
+
+```shell
+echo '
+[gitaly-ruby]
+dir = "/home/git/gitaly/ruby"
+
+[gitlab-shell]
+dir = "/home/git/gitlab-shell"
+' | sudo -u git tee -a /home/git/gitaly/config.toml
+```
+
+#### Check Gitaly configuration
+
+Due to a bug in the `rake gitlab:gitaly:install` script your Gitaly
+configuration file may contain syntax errors. The block name
+`[[storages]]`, which may occur more than once in your `config.toml`
+file, should be `[[storage]]` instead.
+
+```shell
+sudo -u git -H sed -i.pre-10.1 's/\[\[storages\]\]/[[storage]]/' /home/git/gitaly/config.toml
+```
+
+#### Compile Gitaly
+
+```shell
+cd /home/git/gitaly
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITALY_SERVER_VERSION)
+sudo -u git -H make
+```
+
+### 10. Update MySQL permissions
+
+If you are using MySQL you need to grant the GitLab user the necessary
+permissions on the database:
+
+```bash
+mysql -u root -p -e "GRANT TRIGGER ON \`gitlabhq_production\`.* TO 'git'@'localhost';"
+```
+
+If you use MySQL with replication, or just have MySQL configured with binary logging,
+you will need to also run the following on all of your MySQL servers:
+
+```bash
+mysql -u root -p -e "SET GLOBAL log_bin_trust_function_creators = 1;"
+```
+
+You can make this setting permanent by adding it to your `my.cnf`:
+
+```
+log_bin_trust_function_creators=1
+```
+
+### 11. Update configuration files
+
+#### New configuration options for `gitlab.yml`
+
+There might be configuration options available for [`gitlab.yml`][yaml]. View them with the command below and apply them manually to your current `gitlab.yml`:
+
+```sh
+cd /home/git/gitlab
+
+git diff origin/10-4-stable:config/gitlab.yml.example origin/10-5-stable:config/gitlab.yml.example
+```
+
+#### Nginx configuration
+
+Ensure you're still up-to-date with the latest NGINX configuration changes:
+
+```sh
+cd /home/git/gitlab
+
+# For HTTPS configurations
+git diff origin/10-4-stable:lib/support/nginx/gitlab-ssl origin/10-5-stable:lib/support/nginx/gitlab-ssl
+
+# For HTTP configurations
+git diff origin/10-4-stable:lib/support/nginx/gitlab origin/10-5-stable:lib/support/nginx/gitlab
+```
+
+If you are using Strict-Transport-Security in your installation to continue using it you must enable it in your Nginx
+configuration as GitLab application no longer handles setting it.
+
+If you are using Apache instead of NGINX please see the updated [Apache templates].
+Also note that because Apache does not support upstreams behind Unix sockets you
+will need to let gitlab-workhorse listen on a TCP port. You can do this
+via [/etc/default/gitlab].
+
+[Apache templates]: https://gitlab.com/gitlab-org/gitlab-recipes/tree/master/web-server/apache
+[/etc/default/gitlab]: https://gitlab.com/gitlab-org/gitlab-ce/blob/10-5-stable/lib/support/init.d/gitlab.default.example#L38
+
+#### SMTP configuration
+
+If you're installing from source and use SMTP to deliver mail, you will need to add the following line
+to config/initializers/smtp_settings.rb:
+
+```ruby
+ActionMailer::Base.delivery_method = :smtp
+```
+
+See [smtp_settings.rb.sample] as an example.
+
+[smtp_settings.rb.sample]: https://gitlab.com/gitlab-org/gitlab-ce/blob/10-5-stable/config/initializers/smtp_settings.rb.sample#L13
+
+#### Init script
+
+There might be new configuration options available for [`gitlab.default.example`][gl-example]. View them with the command below and apply them manually to your current `/etc/default/gitlab`:
+
+```sh
+cd /home/git/gitlab
+
+git diff origin/10-4-stable:lib/support/init.d/gitlab.default.example origin/10-5-stable:lib/support/init.d/gitlab.default.example
+```
+
+Ensure you're still up-to-date with the latest init script changes:
+
+```bash
+cd /home/git/gitlab
+
+sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab
+```
+
+For Ubuntu 16.04.1 LTS:
+
+```bash
+sudo systemctl daemon-reload
+```
+
+### 12. Install libs, migrations, etc.
+
+```bash
+cd /home/git/gitlab
+
+# MySQL installations (note: the line below states '--without postgres')
+sudo -u git -H bundle install --without postgres development test --deployment
+
+# PostgreSQL installations (note: the line below states '--without mysql')
+sudo -u git -H bundle install --without mysql development test --deployment
+
+# Optional: clean up old gems
+sudo -u git -H bundle clean
+
+# Run database migrations
+sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production
+
+# Compile GetText PO files
+
+sudo -u git -H bundle exec rake gettext:compile RAILS_ENV=production
+
+# Update node dependencies and recompile assets
+sudo -u git -H bundle exec rake yarn:install gitlab:assets:clean gitlab:assets:compile RAILS_ENV=production NODE_ENV=production
+
+# Clean up cache
+sudo -u git -H bundle exec rake cache:clear RAILS_ENV=production
+```
+
+**MySQL installations**: Run through the `MySQL strings limits` and `Tables and data conversion to utf8mb4` [tasks](../install/database_mysql.md).
+
+### 13. Start application
+
+```bash
+sudo service gitlab start
+sudo service nginx restart
+```
+
+### 14. Check application status
+
+Check if GitLab and its environment are configured correctly:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production
+```
+
+To make sure you didn't miss anything run a more thorough check:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production
+```
+
+If all items are green, then congratulations, the upgrade is complete!
+
+## Things went south? Revert to previous version (10.4)
+
+### 1. Revert the code to the previous version
+
+Follow the [upgrade guide from 10.3 to 10.4](10.3-to-10.4.md), except for the
+database migration (the backup is already migrated to the previous version).
+
+### 2. Restore from the backup
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H bundle exec rake gitlab:backup:restore RAILS_ENV=production
+```
+
+If you have more than one backup `*.tar` file(s) please add `BACKUP=timestamp_of_backup` to the command above.

+
+## Source installation
+
+### Prerequisites
+
+#### Install PostgreSQL and create database
+
+See [installation guide](../install/installation.md#6-database).
+
+#### Install [pgloader](http://pgloader.io) 3.4.1+
+
+Install directly from your distro:
+``` bash
+sudo apt-get install pgloader
+```
+
+If this version is too old, use PostgreSQL's repository:
+``` bash
+# add repository
+sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
+
+# add key
+sudo apt-get install wget ca-certificates
+wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
+
+# install package
+sudo apt-get update
+sudo apt-get install pgloader
+```
+
+### Enable bundled PostgreSQL database
+
+1. Stop GitLab:
+
+    ``` bash
+    sudo service gitlab stop
+    ```
+
+1. Switch database from MySQL to PostgreSQL
+
+   ``` bash
+   cd /home/git/gitlab
+   sudo -u git mv config/database.yml config/database.yml.bak
+   sudo -u git cp config/database.yml.postgresql config/database.yml
+   sudo -u git -H chmod o-rwx config/database.yml
+   ```
+
+1. Run the following commands to prepare the schema:
+
+    ``` bash
+    sudo -u git -H bundle exec rake db:create db:migrate RAILS_ENV=production
+    ```
+
+After these steps, you'll have a fresh PostgreSQL database with up-to-date schema.
+
+### Migrate data from MySQL to PostgreSQL
+
+Now, you can use pgloader to migrate the data from MySQL to PostgreSQL:
+
+1. Save the following snippet in a `commands.load` file, and edit with your
+   MySQL `username`, `password` and `host`:
+
+    ```
+    LOAD DATABASE
+         FROM mysql://username:password@host/gitlabhq_production
+         INTO postgresql://postgres@unix://var/run/postgresql:/gitlabhq_production
+
+    WITH include no drop, truncate, disable triggers, create no tables,
+         create no indexes, preserve index names, no foreign keys,
+         data only
+
+    ALTER SCHEMA 'gitlabhq_production' RENAME TO 'public'
+
+    ;
+    ```
+
+1. Start the migration:
+
+    ``` bash
+    sudo -u postgres pgloader commands.load
+    ```
+
+1. Once the migration finishes, you should see a summary table that looks like
+the following:
+
+
+    ```

 # Labels
 
-Labels provide an easy way to categorize the issues or merge requests based on
-descriptive titles like `bug`, `documentation` or any other text you feel like.
-They can have different colors, a description, and are visible throughout
-the issue tracker or inside each issue individually.
+## Overview
 
-With labels, you can navigate the issue tracker and filter any bloated
-information to visualize only the issues you are interested in. Let's see how
-that works.
+Labels allow you to categorize issues or merge requests using descriptive titles like `bug`, `feature request`, or `docs`. Each label also has a customizable color. They allow you to quickly and dynamically filter and manage issues or merge requests you care about, and are visible throughout GitLab in most places where issues and merge requests are located.
 
-## Create new labels
+## Project labels and group labels
+
+In GitLab, you can create project and group labels:
+
+- **Project labels** can be assigned to issues or merge requests in that project only. 
+- **Group labels** can be assigned to any issue or merge request of any project in that group. 
+- In the [future](https://gitlab.com/gitlab-org/gitlab-ce/issues/40915), you will be able to assign group labels to issues and merge reqeusts of projects in [subgroups](../group/subgroups/index.md).
+
+## Creating labels
 
 >**Note:**
-A permission level of `Developer` or higher is required in order to manage
-labels.

-The first time you visit this page, you'll notice that there are no labels
-created yet.
+To create a **project label**, navigate to **Issues > Labels** in the project.
 
-Creating a new label from scratch is as easy as pressing the **New label**
-button. From there on you can choose the name, give it an optional description,
-a color and you are set.
+Click the **New label** button. Enter the title, an optional description, and the background color. Click **Create label** to create the label.

+### New project label from sidebar
 
-You can see that from the labels page you can have an overview of the number of
-issues and merge requests assigned to each label.
+From the sidebar of an issue or a merge request, you can create a create a new **project label** inline immediately, instead of navigating to the project label list page.
 
-## Prioritize labels
+![Labels inline](img/new_label_from_sidebar.gif)
 
->**Notes:**
->
-> - Introduced in GitLab 8.9.
-> - Priority sorting is based on the highest priority label only. This might
->   change in the future, follow the discussion in
->   https://gitlab.com/gitlab-org/gitlab-ce/issues/18554.
+## Editing labels
 
-Prioritized labels are like any other label, but sorted by priority. This allows
-you to sort issues and merge requests by label priority.
+NOTE: **Note:**
+A permission level of `Developer` or higher is required in order to edit labels.
 
-To prioritize labels, navigate to your project's **Issues > Labels** and click
-on the star icon next to them to put them in the priority list. Click on the
-star icon again to remove them from the list.
+You can update a label by navigating to **Issues > Labels** in the project ot group and clicking the pencil icon.
 
-From there, you can drag them around to set the desired priority. Priority is
-set from high to low with an ascending order. Labels with no priority, count as
-having their priority set to null.
+You can delete a label by clicking the trash icon.
 
-![Prioritize labels](img/labels_prioritize.png)
+### Promoting project labels to group labels
 
-Now that you have labels prioritized, you can use the 'Label priority' and 'Priority' 
-sort orders in the issues or merge requests tracker.
+If you are expanding from a few projects to a larger number of projects within the same group, you may want to share the same label among multiple projects in the same group. If you previously created a project label and now want to make it available for other projects, you can promote it to a group label.
 
-In the following, everything applies to both issues and merge requests, but we'll
-refer to just issues for brevity.
+From the project label list page, you can promote a project label to a group label. This will merge all project labels across all projects in this group with the same name into a single group label. All issues and merge requests that previously were assigned one of these project labels will now be assigned the new group label. This action cannot be reversed and the changes are permanent.
 
-The 'Label priority' sort order positions issues with higher priority labels
-toward the top, and issues with lower priority labels toward the bottom. A non-prioritized
-label is considered to have the lowest priority. For a given issue, we _only_ consider the
-highest priority label assigned to it in the comparison. ([We are discussing](https://gitlab.com/gitlab-org/gitlab-ce/issues/18554) 
-including all the labels in a given issue for this comparison.) Given two issues
-are equal according to this sort comparison, their relative order is equal, and 
-therefore it's not guaranteed that one will be always above the other.
+![Labels promotion](img/labels_promotion.png)
 
-![Label priority sort order](img/label_priority_sort_order.png)
+## Assigning labels from the sidebar
 
-The 'Priority' sort order comparison first considers an issue's milestone's due date,
-(if the issue is assigned a milestone and the milestone's due date exists), and then 
-secondarily considers the label priority comparison above. Sooner due dates results
-a higher sort order. If an issue doesn't have a milestone due date, it is equivalent to
-being assigned to a milestone that has a due date in the infinite future. Given two issues
-are equal according to this two-stage sort comparison, their relative order is equal, and 
-therefore it's not guaranteed that one will be always above the other.
+Every issue and merge request can be assigned any number of labels. The labels are visible on every issue and merge request page, in the sidebar. They are also visible in the issue board. From the sidebar, you can assign or unassign a label to the object (i.e. label or unlabel it). You can also perform this as a [quick action](quick_actions.md) in a comment.

-## Assigning labels to issues and merge requests
+## Label priority
 
-There are generally two ways to assign a label to an issue or merge request.
+>**Notes:**
+>
+> - Introduced in GitLab 8.9.
+> - Priority sorting is based on the highest priority label only. [This discussion](https://gitlab.com/gitlab-org/gitlab-ce/issues/18554) considers changing this.
 
-The first one is to assign a label when you first create or edit an issue or
-merge request.
+Labels can have relative priorities, which are used in the "Label priority" and "Priority" sort orders of the issue and merge request list pages.
 
-The second way is by using the right sidebar when inside an issue or merge
-request. Expand it and hit **Edit** in the labels area. Start typing the name
-of the label you are looking for to narrow down the list, and select it. You
-can add more than one labels at once. When done, click outside the sidebar area
-for the changes to take effect.
+From the project label list page, star a label to indicate that it has a priority. Drag starred labels up and down to change their priority. Higher means higher priority. Prioritization happens at the project level, only on the project label list page, and not on the group label list page. However, both project and group labels can be prioritized on the project label list page since both types are displayed on the project label list page.

----
+On the project and group issue and merge request list pages, you can sort by `Label priority` and `Priority`, which account for objects (issues and merge requests) that have prioritized labels assigned to them.
 
-To remove labels, expand the left sidebar and unmark them from the labels list.
-Simple as that.
+If you sort by `Label priority`, GitLab considers this sort comparison order:
 
-##  Use labels to filter issues
+- Object with a higher priority prioritized label.
+- Object without a prioritized label.
 
-Once you start adding labels to your issues, you'll see the benefit of it.
-Labels can have several uses, one of them being the quick filtering of issues
-or merge requests.
+Ties are broken arbitrarily. (Note that we _only_ consider the highest prioritized label in an object, and not any of the lower prioritized labels. [This discussion](https://gitlab.com/gitlab-org/gitlab-ce/issues/18554) considers changing this.)
 
-Pick an existing label from the dropdown _Label_ menu or click on an existing
-label from the issue tracker. In the latter case, you also get to see the
-label description like shown below.
+![Labels sort label priority](img/labels_sort_label_priority.png)
 
-![Filter labels](img/labels_filter.png)
+If you sort by `Priority`, GitLab considers this sort comparison order:
 
----
+- Object's assigned [milestone](milestones/index.md)'s due date is sooner, provided the object has a milestone and the milestone has a due date. If this isn't the case, consider the object having a due date in the infinite future.
+- Object with a higher priority prioritized label.
+- Object without a prioritized label.
 
-And if you added a description to your label, you can see it by hovering your
-mouse over the label in the issue tracker or wherever else the label is
-rendered.
+Ties are broken arbitrarily.

+Let's start with an introduction to the importance of HTTPS.
+Alternatively, jump ahead to [adding certificates to your project](#adding-certificates-to-your-project).
 
-The reason why certificates are so important is that they encrypt
+#### Why should I care about HTTPS?
+
+This might be your first question. If our sites are hosted by GitLab Pages,
+they are static, hence we are not dealing with server-side scripts
+nor credit card transactions, then why do we need secure connections?
+
+Back in the 1990s, where HTTPS came out, [SSL](https://en.wikipedia.org/wiki/Transport_Layer_Security#SSL_1.0.2C_2.0_and_3.0) was considered a "special"
+security measure, necessary just for big companies, like banks and shoppings sites
+with financial transactions.
+Now we have a different picture. [According to Josh Aas](https://letsencrypt.org/2015/10/29/phishing-and-malware.html), Executive Director at [ISRG](https://en.wikipedia.org/wiki/Internet_Security_Research_Group):
+
+> _We’ve since come to realize that HTTPS is important for almost all websites. It’s important for any website that allows people to log in with a password, any website that [tracks its users](https://www.washingtonpost.com/news/the-switch/wp/2013/12/10/nsa-uses-google-cookies-to-pinpoint-targets-for-hacking/) in any way, any website that [doesn’t want its content altered](http://arstechnica.com/tech-policy/2014/09/why-comcasts-javascript-ad-injections-threaten-security-net-neutrality/), and for any site that offers content people might not want others to know they are consuming. We’ve also learned that any site not secured by HTTPS [can be used to attack other sites](http://krebsonsecurity.com/2015/04/dont-be-fodder-for-chinas-great-cannon/)._
+
+Therefore, the reason why certificates are so important is that they encrypt
 the connection between the **client** (you, me, your visitors)
 and the **server** (where you site lives), through a keychain of
 authentications and validations.
 
+How about taking Josh's advice and protecting our sites too? We will be
+well supported, and we'll contribute to a safer internet.
+
+#### Organizations supporting HTTPS
+
+There is a huge movement in favor of securing all the web. W3C fully
+[supports the cause](https://w3ctag.github.io/web-https/) and explains very well
+the reasons for that. Richard Barnes, a writer for Mozilla Security Blog,
+suggested that [Firefox would deprecate HTTP](https://blog.mozilla.org/security/2015/04/30/deprecating-non-secure-http/),
+and would no longer accept unsecured connections. Recently, Mozilla published a
+[communication](https://blog.mozilla.org/security/2016/03/29/march-2016-ca-communication/)
+reiterating the importance of HTTPS.

+### Serving compressed assets
+
+Most modern browsers support downloading files in a compressed format. This
+speeds up downloads by reducing the size of files.
+
+Before serving an uncompressed file, Pages will check whether the same file
+exists with a `.gz` extension. If it does, and the browser supports receiving
+compressed files, it will serve that version instead of the uncompressed one.
+
+To take advantage of this feature, the artifact you upload to the Pages should
+have this structure:
+
+```
+public/
+├─┬ index.html
+│ └ index.html.gz
+│
+├── css/
+│   └─┬ main.css
+│     └ main.css.gz
+│
+└── js/
+    └─┬ main.js
+      └ main.js.gz
+```
+
+This can be achieved by including a `script:` command like this in your
+`.gitlab-ci.yml` pages job:
+
+```yaml
+pages:
+  # Other directives
+  script:
+    - # build the public/ directory first
+    - find public -type f -iregex '.*\.\(htm\|html\|txt\|text\|js\|css\)$' -execdir gzip -f --keep {} \;
+```
+
+By pre-compressing the files and including both versions in the artifact, Pages
+can serve requests for both compressed and uncompressed content without
+needing to compress files on-demand.
+

+## File Locking
+
+The first thing to do before using File Locking is to tell Git LFS which
+kind of files are lockable. The following command will store PNG files
+in LFS and flag them as lockable:
+
+```bash
+git lfs track "*.png" --lockable
+```
+
+After executing the above command a file named `.gitattributes` will be
+created or updated with the following content:
+
+```bash
+*.png filter=lfs diff=lfs merge=lfs -text lockable
+```
+
+You can also register a file type as lockable without using LFS
+(In order to be able to lock/unlock a file you need a remote server that implements the  LFS File Locking API),
+in order to do that you can edit the `.gitattributes` file manually:
+
+```bash
+*.pdf lockable
+```
+
+After a file type has been registered as lockable, Git LFS will make
+them readonly on the file system automatically. This means you will
+need to lock the file before editing it.
+
+### Managing Locked Files
+
+Once you're ready to edit your file you need to lock it first:
+
+```bash
+git lfs lock images/banner.png
+Locked images/banner.png
+```
+
+This will register the file as locked in your name on the server:
+
+```bash
+git lfs locks
+images/banner.png  joe   ID:123
+```
+
+Once you have pushed your changes, you can unlock the file so others can
+also edit it:
+
+```bash
+git lfs unlock images/banner.png
+```
+
+You can also unlock by id:
+
+```bash
+git lfs unlock --id=123
+```
+
+If for some reason you need to unlock a file that was not locked by you,
+you can use the `--force` flag as long as you have a `master` access on
+the project:
+
+```bash
+git lfs unlock --id=123 --force
+```
