## Summary Currently, handbook development is using `asdf` because that's what Engineering was using at the time. Engineering has now moved to `mise` as a package manager and we've had numerous requests about it. For example, !14170 We can't have both because they use different package names for `hugo-extended` and while `asdf` will ignore packages it can't find, `mise` will not. ## Implementation plan We need to: 1. Test local development using `mise` instead of `asdf`. 2. Update documentation on running the local dev environment, including the troubleshooting section: https://handbook.gitlab.com/docs/development/running-locally/ 3. Update the various projects to use `mise` instead. 4. Mention the `handbook-tools` group and post in `#handbook` Slack channel with any particular notes on migrating.
