The docs for v0.1.0 (https://fluxml.ai/OneHotArrays.jl/v0.1.0/) currently lead to a 404 page. The docs are also missing from the gh-pages branch - https://github.com/FluxML/OneHotArrays.jl/tree/gh-pages. The docs should've been generated automatically (I don't know why they weren't in the first place), but they can be generated manually by someone who has push access to main -

git tag -a v0.1.0+docs -m "Build and deploy docs for v0.1.0"
git push --tags

The new v0.1.0+docs tag will automatically trigger the Documenter workflow to generate and deploy v0.1.0 docs.

Additionally, the docs URL should be added to project's about section -
