ML experiment: Explain this source code

What this post added

This post details an experiment with an 'Explain this Code' feature, a rapid prototype developed by engineers. It leverages AI models to provide natural language explanations of source code directly within GitLab's repository source code file viewer. The feature allows users to highlight code selections and receive explanations, aiming to help developers quickly understand new projects, unfamiliar languages, or complex historical code. The post also mentions potential extensions to merge requests and snippets, and reiterates the ongoing effort to infuse AI/ML capabilities across the software development lifecycle.
