I'm a GitLab team member. Here are a few resources I would recommend:

1. GitLab University is our training portal and has plenty of CI/CD content and courses - https://university.gitlab.com/pages/ci-cd-content

2. GitLab's docs provide tutorials for many topics and include written and video content for different types of learners. You may want to start with the topics marked "Good for beginners" - https://docs.gitlab.com/ee/tutorials/build_application.html
