Repository: truera/trulens
Issue: [BUG] Some docs broken / 404?
Root cause: Documentation Deficiency

**Bug Description**
Hey when browsing your docs I get 404 errors for https://www.trulens.org/install/,  https://www.trulens.org/trulens_eval/core_concepts/feedback_functions/ and https://www.trulens.org/trulens_eval/core_concepts/honest_harmless_helpful_evals/. I got there from the standard github docs link the top of the repo.

Same result in chrome and firefox from my desktop.

Example image:

I can read the docs fine using https://www.trulens.org/trulens_eval/getting_started/ and browsing from there but I think your links are messed up/outdated on the github side.




<!-- Answer -->
Based on the information you've provided, it seems like the issue might be due to incorrect or outdated URLs in the GitHub repository's documentation links. The TruLens documentation site's structure and URLs are determined by the organization of content in the `nav` section of the `mkdocs.yml` file, and the file paths specified there. If these paths are not correctly specified or updated when files are moved or renamed, it can lead to 404 errors.

For example, the URL for the "🚀 Getting Started" section's "Installation" page would be generated from the file path `trulens_eval/getting_started/install.md`, resulting in a URL that appends this path to the base URL of the documentation site, typically following a pattern like `https://<base-url>/trulens_eval/getting_started/install/`.

If the links on the GitHub repository are not updated to reflect these changes, they may still point to the old URLs, causing 404 errors when accessed. This could be the case with the URLs you've mentioned: https://www.trulens.org/install/, https://www.trulens.org/trulens_eval/core_concepts/feedback_functions/, and https://www.trulens.org/trulens_eval/core_concepts/honest_harmless_helpful_evals/.

To resolve this issue, the links on the GitHub repository need to be updated to match the current URLs on the documentation site. This would typically involve updating the `README.md` or other relevant files in the repository where these links are located.

I hope this helps clarify the issue. If you have any further questions or need additional assistance, please don't hesitate to ask.

Thanks for noticing. Looks like `getting_started` was not added to these paths after a recent docs folder reorganization. Will fix shortly.

Links updated.
