Basic knowledge of the Linux command-line

Step 1: Install GitLab CE

GitLab CI is a part of GitLab CE (Community Edition). Therefore, we need to install GitLab CE first. Follow these steps to install GitLab CE on Manjaro.

Open the terminal by pressing Ctrl + Alt + T.
Update the package manager of your system:

Add the GitLab package repository to Manjaro:

curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash

Install GitLab CE:
```
sudo pacman -S gitlab-ce
```
Once the installation is complete, you can start the GitLab service by running the following command:
```
sudo systemctl start gitlab-runsvdir.service
```

Verify that the GitLab service is running:

sudo gitlab-ctl status

You should see output similar to the following:
