I just uploaded another project dataset (an RNAseq study) to SRA, BioSample, and BioProject - and along the way created step by step slide deck with screenshots of the process (web page captures and metadata tables, etc). Let me know if you're interested and I'll be happy to share it .
I remember early in my career uploading to NCBI correctly was a dark art (most people skip steps or don't bother with all the metadata, used off brand annotations, or just read "optional" as "skip it" - which sadly often makes data reuse a massive hurdle later on), so.... I'm training my team later this week on how to do it "right" (at least IMHO the right way). The deck is ~47 slides... so... maybe it will be helpful to someone else too?
I'm getting feedback from the team on the deck later this week. once I've updated it - I'll share it if anyone is interested. probably will throw it over onto Git or gDrive or something.
