Description

https://github.com/autowarefoundation/autoware/packages

Packages:

• autoware-universe
• autoware-openadk
• autoware
• autoware-openadk-modular
• openadkit

@oguzkaganozt @youtalk could you please remove (if you don't have permissions, I can remove them too) unused packages from here?

And for the remaining, could you add a documentation to a suitable place where people can see and understand what to use when?

Right now this page is a mess and very confusing for newcomers.

Also we can't keep renaming these packages as people rely on these to be stable. Let's discuss what to keep in the open ad kit wg and move forward that way.

Also when these are renamed, the community should also be alerted through github, discord announcements. And a timeline for transition should be provided.

I think these packages are no longer needed. @oguzkaganozt What do you think?

• autoware-universe
• autoware-openadk
• autoware-openadk-modular
