This tutorial provides a detailed guide on automating the generation of release notes for GitHub repositories using Node.js and CircleCI. It describes the setup process for a Node.js app that uses the GitHub API to fetch issues and pull requests, which are then compiled into a report and committed back to the repository. The tutorial explains how to create a CircleCI pipeline to automate this process, including configuring CircleCI to run the pipeline when changes are pushed to the master branch. Additionally, it covers setting up SSH keys for CircleCI to enable write access to GitHub, ensuring the generated reports can be automatically committed. By following these steps, users can streamline the creation of release notes, making the process less time-consuming and more efficient by scheduling the pipeline to run weekly.
