Building a GitLab CI/CD pipeline for a monorepo the easy way

This post introduces a new best practice for managing CI/CD pipelines in monorepos within GitLab. It details the evolution from a legacy approach using hidden jobs and extensive `extends` directives to a more streamlined method leveraging the `include` keyword with `rules:changes` in GitLab 16.4. This new approach allows for conditional inclusion of application-specific YAML pipeline files based on changes within designated directories, reducing code duplication and improving flexibility.
