Worked on improving onboarding documentation for Aalto Mac users in the AaltoSciComp/scicomp-docs repository, focusing on aligning technical resources with current ITS standards. Enhanced the clarity and accessibility of guides for first-time setup, password changes, admin rights, and managed software, using reStructuredText (RST) for structured documentation. Updated installation instructions for .dmg files and detailed the use of the managed software center, incorporating revised program names and ITS procedures. Emphasized technical writing and documentation skills to reduce user confusion and support requests, ensuring that onboarding materials accurately reflected the latest institutional resources and streamlined the setup process for new users.
