Pedro Ojeda contributed to the UPPMAX/R-matlab-julia-HPC repository by refining documentation to enhance onboarding clarity for high-performance computing users. Focusing on the Parallel Programming Tools Guidance, Pedro updated the documentation wording from "Familiarize with the tools" to "Get familiar with the tools," aligning the language with internal standards and improving consistency across onboarding materials. This work involved editing reStructuredText (RST) files and applying documentation best practices, ensuring that the change was non-functional and did not impact code, tests, or builds. The contribution demonstrated attention to detail in documentation and supported clearer communication for future users and contributors.
