Docs-review found two gaps a first-time user would hit: the "clone the
repository" step had no actual `git clone` command, and git was not listed as
a prerequisite (it is needed to fetch the source and is how Relicario stores/
syncs the vault). Add an explicit clone+cd step and list git alongside Rust.
All four v0.8.1 streams merged (main 4c0a289): org add now supports all 7 item
types (card/key/totp/document) and org edit is interactive. Flip the two
high-level org sections from "coming" to shipped, grounded in the real merged
`relicario org add <type> --collection …` surface; remove the rebase TODO markers.
A friendly, task-oriented guide for non-technical users: README index,
getting-started, concepts, items, passwords-and-generators, totp,
attachments-and-documents, organizing, sync-and-backup, the-browser-extension,
recovery, faq. Every command/flag derived from the actual CLI surface
(`relicario --help` tree) and real extension behavior — no invented flags.
Org item-type parity is covered high-level pending the v0.8.1 B/C merge
(two TODO markers left for the rebase).
