 For more information about configuring Gitaly see
 [the Gitaly documentation](../administration/gitaly/index.md).
 
+### Install the service
+
+GitLab has always supported SysV init scripts, which are widely supported and portable, but now systemd is the standard for service supervision and is used by all major Linux distributions. You should use native systemd services if you can to benefit from automatic restarts, better sandboxing and resource control.
+
+#### Install systemd units
+
+Use these steps if you use systemd as init. Otherwise, follow the [SysV init script steps](#install-sysv-init-script).
+
+Copy the services and run `systemctl daemon-reload` so that systemd picks them up:
+
+```shell
+cd /home/git/gitlab
+sudo mkdir -p /usr/local/lib/systemd/system
+sudo cp lib/support/systemd/* /usr/local/lib/systemd/system/
+sudo systemctl daemon-reload
+```
+
+The units provided by GitLab make very little assumptions about where you are running Redis and PostgreSQL.
+
+If you installed GitLab in another directory or as a user other than the default, you need to change these values in the units as well.
+
+For example, if you're running Redis and PostgreSQL on the same machine as GitLab, you should:
+
+- Edit the Puma service:
+
+  ```shell
+  sudo systemctl edit gitlab-puma.service
+  ```
+
+  In the editor that opens, add the following and save the file:
+
+  ```plaintext
+  [Unit]
+  Wants=redis-server.service postgresql.service
+  After=redis-server.service postgresql.service
+  ```
+
+- Edit the Sidekiq service:
+
+  ```shell
+  sudo systemctl edit gitlab-sidekiq.service
+  ```
+
+  Add the following and save the file:
+
+  ```plaintext
+  [Unit]
+  Wants=redis-server.service postgresql.service
+  After=redis-server.service postgresql.service
+  ```
+
+`systemctl edit` installs drop-in configuration files at `/etc/systemd/system/<name of the unit>.d/override.conf`, so your local configuration is not overwritten when updating the unit files later. To split up your drop-in configuration files, you can add the above snippets to `.conf` files under `/etc/systemd/system/<name of the unit>.d/`.
+
+If you manually made changes to the unit files or added drop-in configuration files (without using `systemctl edit`), run the following command for them to take effect:
+
+```shell
+sudo systemctl daemon-reload
+```
+
+Make GitLab start on boot:
+
+```shell
+sudo systemctl enable gitlab.target
+```
+
+#### Install SysV init script
+
+Use these steps if you use the SysV init script. If you use systemd, follow the [systemd unit steps](#install-systemd-units).
+
+Download the init script (is `/etc/init.d/gitlab`):
+
+```shell
+cd /home/git/gitlab
+sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab

+
+And if you are installing with a non-default folder or user, copy and edit the defaults file:
+
+```shell
+sudo cp lib/support/init.d/gitlab.default.example /etc/default/gitlab
+```
+
+If you installed GitLab in another directory or as a user other than the default, you should change these settings in `/etc/default/gitlab`. Do not edit `/etc/init.d/gitlab` as it is changed on upgrade.
+
+Make GitLab start on boot:
