Worked on the EspressoSystems/nitro-espresso-integration repository to enhance developer onboarding by consolidating and clarifying the E2E testing workflow and build prerequisites. Focused on improving the README documentation, the work introduced MacOS-specific instructions for building WASM components and setting up the environment, as well as emphasizing the requirement for a running Docker daemon to ensure consistent and isolated E2E test execution. Adjusted the sequencing of build and test steps to minimize setup errors and reduce developer confusion. Utilized Bash, Go, and Markdown to implement these documentation and CI/CD improvements, prioritizing cross-platform compatibility and a smoother onboarding experience.
