Cycle 5 data deliveries currently may not contain an informative README. Unfortunately, the tools that package and ingest data into the archive are not yet placing a QA2 report in the qa directory. 
As PI or Co-I of a project, to find the QA0 and QA2 reports please go to the project view in SnooPi.
More details can be found in Chapter 4 of the SnooPI User documentation

If you would like a copy of the QA2 or QA0 report of a Cycle 5 project that is now public, please submit a ticket to the Archive and Data Retrieval department.
