RustPost's README mixed first-time setup with a long technical reference. This update explains the app in everyday language, puts the released Docker container setup first, and gives readers clear choices between Docker, a downloaded app, and a source build.

Detailed configuration, Tor, backup safeguards, and release advisory notes are preserved in an operator guide. A Docker guide adds tested settings, storage, backup/restore, and container replacement commands. Five screenshots were recaptured from a fresh v1.0.0 demo, and the demo guide records prerequisites, pages, and viewport sizes.

Validation:

• cargo build --workspace --all-features --bin rustpost-cli passed.
• cargo fmt --all --check passed.
• cargo clippy --workspace --all-targets --all-features -- -D warnings -D clippy::all -D clippy::pedantic -D clippy::nursery -D clippy::cargo passed.
• cargo test --workspace --all-features passed (487 tests).
• Published GHCR manifest verified for Linux amd64 and arm64.
• Released container smoke passed: first boot, interactive administrator creation, HTTP, settings copy/validation, backup, restore, and persistence after container replacement.
• Documentation links/anchors and code fences checked; all five screenshots visually reviewed; browser console had no errors.

No application code or dependencies changed. Existing upstream dependency caveats remain documented.
