Worked on the luoyuxia/fluss repository to update the Docker Quickstart documentation, focusing on improving onboarding clarity for new contributors. The update replaced the use of 'docker container ls -a' with 'docker compose ps' to check running containers, aligning the documentation with current Docker best practices and reducing confusion during initial setup. This change, implemented using Markdown and leveraging Docker expertise, enhanced the accuracy of verification steps and streamlined the onboarding process. All modifications were carefully documented and linked to a specific issue for traceability, demonstrating disciplined documentation practices and attention to detail in maintaining clear, actionable technical guidance.
