Create FTP guide for users of hosted Meltano instances and add to Documentation
Create a public-facing guide that users can follow during our setup calls in case they need to use FTP to upload a file to their Meltano instance (in the case of the CSV Extractor)
This should live in our docs. We might need a section for the Hosted Instance service.
