Worked on the meteor/meteor repository to enhance deployment documentation, focusing on the METEOR_SETTINGS environment variable. The approach centered on updating Markdown-based guides and the bundle README template to provide clearer instructions for configuring environment variables during deployment. Leveraging skills in the Meteor framework and documentation best practices, the work aimed to streamline user onboarding and reduce confusion around deployment processes. No code changes were made beyond documentation, but the updates addressed issue #13458 by clarifying environment variable usage. This documentation-driven effort improved the overall clarity of deployment steps, helping users adopt best practices when deploying Meteor applications with JavaScript.
