----

-## Summary / Background
-What do you want to achieve, why? business context
-...
-
-## Scope
-
-What will be impacted and what won't be?
-What needs implementation and what is invariant?
-e.g.
-- user should be able to run workflow X from UI
-- enable workflow Y, Z from CLI
-
-## Assumptions
-Product / UX assumptions as well as technical assumptions / limitations
-e.g.
-* Support only Python Runtime
-* Focus on DVC experiments only
-* Deployment environments don't change often and can be picked up from shared configuration
-
-## Open Questions
-e.g.
-- How should access control work for shared artifacts (workflow X)
-- Python runtime assumption - is it really valid? in light of <...>
-
-## Blockers / Dependencies
-List issues or other conditions / blockers
-
-## General Approach
-Invocation example:
-```shell
-$ mapper-run task.tar.gz --ray-cluster <ip>:<port>
-```
-
-## Steps
-
-### Must have (p1)
-- [ ] subissue2
-- [ ] step 2
- - info
- - info
-
-### Optional / followup (p2)
-- [ ] ⌛ step 3 wip
-- [ ] step 4
-
-## Timelines
-
-Put your estimations here. Update once certainty changes
-- end of week (Feb 3) for prototype with workflows X, Y
-- Feb 15 - MVP in production
-- Low priority followups can be done later
