Start by reading the Desktop Wallet sections in the eight linked .rst files: create-identity.rst, create-account.rst, change-account-name.rst, recovery.rst, export-import.rst, change-passcode-mw.rst, address-book.rst, and transaction-report.rst. Verify their technical accuracy and completeness, identify missing information, and remove irrelevant or redundant content.
