 ## How does it work?
 
-The Elasticsearch integration depends on an external indexer. We ship a [ruby indexer](https://gitlab.com/gitlab-org/gitlab-ee/blob/master/bin/elastic_repo_indexer) by default but are also working on an [indexer written in Go](https://gitlab.com/gitlab-org/gitlab-elasticsearch-indexer). The user must trigger the initial indexing via a rake task, but after this is done GitLab itself will trigger reindexing when required via `after_` callbacks on create, update, and destroy that are inherited from [/ee/app/models/concerns/elastic/application_search.rb](https://gitlab.com/gitlab-org/gitlab-ee/blob/master/ee/app/models/concerns/elastic/application_search.rb).

 All indexing after the initial one is done via `ElasticIndexerWorker` (sidekiq jobs).

+### Install gitlab-elasticsearch-indexer
+
+GitLab-Elasticsearch-Indexer uses [GNU Make](https://www.gnu.org/software/make/). The
+following command-line will install GitLab-Elasticsearch-Indexer in `/home/git/gitlab-elasticsearch-indexer`
+which is the recommended location.
+
+```sh
+sudo -u git -H bundle exec rake "gitlab:indexer:install[/home/git/gitlab-elasticsearch-indexer]" RAILS_ENV=production

+
+```sh
+sudo -u git -H bundle exec rake "gitlab:indexer:install[/home/git/gitlab-elasticsearch-indexer,https://example.com/gitlab-elasticsearch-indexer.git]" RAILS_ENV=production
+```
+
+The source code will first be fetched to the path specified by the first parameter. Then a binary will be built under its `bin` directory.
+You will then need to update `gitlab.yml`'s `production -> elasticsearch -> indexer_path` setting to point to that binary.
+
 ### Install GitLab Pages
 
 GitLab Pages uses [GNU Make](https://www.gnu.org/software/make/). This step is optional and only needed if you wish to host static sites from within GitLab. The following commands will install GitLab Pages in `/home/git/gitlab-pages`. For additional setup steps, consult the [administration guide](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/administration/pages/source.md) for your version of GitLab as the GitLab Pages daemon can be run several different ways.
