@cenlinhe I've invited you to be a collaborator on this repository. Once you accept, I'll be able to assign this to you.

[cenlinhe]

I accept this assignment. Do you have a deadline for this doc writing?

[samsrabin]

Thanks, @cenlinhe! I don't think we have a hard deadline yet, but we'd like it to happen before the CTSM6.0 release.

[cenlinhe]

Thanks! I will be busy in the next few weeks, is it OK I complete my writing sometime in July?

[samsrabin]

I think that should be fine, right @wwieder ?
