 # This file stores papers which have used PySR, with

-# Images:
-# - Preferred: set `image:` to an absolute URL (http/https).
-# - If you instead add an image file to this repo (under `docs/src/public/images/`),
-#   set `image:` to the *basename only* (e.g. `myfig.png`), not a path.
-#   a maintainer may apply the `paper-image-sync` label on your PR to trigger an
-#   automation that:
-#     1) resizes/compresses the image,
-#     2) opens a PR to MilesCranmer/PySR_Docs with the processed image,
-#     3) updates this PR to reference the hosted URL (only when the branch is in-repo).
