All: I wasn't sure id this was already clear, so I'm posting.

The main OpenSSF site (openssf.org), under Resources -> Guides,
links to this page with a list of guides: https://openssf.org/resources/guides/
That list includes the following guides from this Working Group:
* Concise Guide for Developing More Secure Software - https://github.com/ossf/wg-best-practices-os-developers/blob/main/docs/Concise-Guide-for-Developing-More-Secure-Software.md#readme
* Concise Guide for Evaluating Open Source Software - https://github.com/ossf/wg-best-practices-os-developers/blob/main/docs/Concise-Guide-for-Evaluating-Open-Source-Software.md#readme
* npm Best Practices Guide - https://github.com/ossf/package-manager-best-practices/blob/main/published/npm.md#readme

This should make these guides easier to find.
