Using the Backed.by platform is not necessary for making changes to your profile/project. Except for platform specific functions that are web2 in nature, you can make changes to your profile, create and edit tiers, and create and edit posts all using web3 tools.
The Backed.by platform uses the following JSON schemas for the documents uploaded to IPFS.
