Hmm, the links work for me and lead to correct sections from guidelines 🤔 Do we prefer a full path for some reason?

[molbap]

it's that it does not work from https://github.com/huggingface/transformers/blob/main/CONTRIBUTING.md is all and it tends to be my first entrypoint 😆 and most other links there do work, haven't checked all though

[zucchini-nlp]

Ah I see, though it will stop working from docs after this PR because it has to be without the .md suffix for it 🥲 Not sure what's the correct way to make it work in both places

[molbap]

no idea either, cc @stevhliu here please 🙏

[stevhliu]

Hmm, I think we can either:

• remove the symlink between the CONTRIBUTING.md on the repo and the docs
• modify the doc-builder to accept the .md extension (this is probably the best since it requires less maintenance)

wdyt?

[molbap]

Yes why not go for the doc-builder change!
