Hi there! Thank you for contributing to XR Blocks! In additional to CONTRIBUTING.md, I'd like to highlight a few contributing point: Demo contributors: for first-time contributor, a new demo that demonstrates novel features in interactive perception, XR realism, embodied interactions, interactive graphics, Gemini capabilities are preferred. E.g., 1) novel use case with open Hugging Face models, 2) port more https://github.com/googlesamples/arcore-depth-lab and https://github.com/google/archat features to XR, 3) converting MIT / Apache 2 shader to XR: https://www.shadertoy.com/view/4sX3Rn (also remember to give credits in README. 4) Finding novel use case of Gemini :) 5) adding accessibility and security layers. All demo submissions should attach an unlisted YouTube video, or screenshots for the expected output. SDK contributors: For small changes, just submit PR; for large changes, maybe create an issue to discuss high-level design first :) Also read https://arxiv.org/abs/2509.25504 a
