+# 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
+```

+![CI/CD pipeline graph](img/cicd_pipeline_infograph.png)
+
+The benefits of Continuous Integration are huge when automation plays an
+integral part of your workflow. GitLab comes with built-in Continuous
+Integration, Continuous Deployment, and Continuous Delivery support to build,
+test, and deploy your application.
+
+Here's some info we've gathered to get you started.
+
+## Getting started
+
+The first steps towards your GitLab CI journey.
 
 - [Getting started with GitLab CI](quick_start/README.md)
-- [CI examples for various languages](examples/README.md)
-- [Learn how to enable or disable GitLab CI](enable_or_disable_ci.md)
 - [Pipelines and jobs](pipelines.md)

 ## Removing indices
 
-If you need to remove index, please add a condition like in following example:
+When removing an index make sure to use the method `remove_concurrent_index` instead
+of the regular `remove_index` method. The `remove_concurrent_index` method
+automatically drops concurrent indexes when using PostgreSQL, removing the
+need for downtime. To use this method you must disable transactions by calling
+the method `disable_ddl_transaction!` in the body of your migration class like
+so:
 
 ```ruby
-remove_index :namespaces, column: :name if index_exists?(:namespaces, :name)
+class MyMigration < ActiveRecord::Migration
+  include Gitlab::Database::MigrationHelpers
+  disable_ddl_transaction!
+
+  def up
+    remove_concurrent_index :table_name, :column_name if index_exists?(:table_name, :column_name)
+  end
+end
 ```
