In this paper, we present the research artifacts for the paper ``Designing for Cognitive Diversity: Improving the GitHub Experience'' accepted in the Software Engineering in Society (SEIS) track at ICSE 2023. In our study, we investigated inclusivity bugs in the GitHub platform itself to support newcomers who are willing to make their first contribution to GitHub, and we proposed and evaluated a plugin that fixes the inclusivity bugs. The research artifacts described in this document include (i) the GenderMag material we used to identify inclusivity bugs; (ii) the proposed fixes and plugin source code; (iii) the evaluation forms; and (iv) the results from the between-subject user study with 75 participants.
