# live-notesPlain-text notes several people edit at once. Each note is one Durable Object, which ordersevery edit and passes it on to the other editors over WebSockets.## How it works- [[conflict-strategy]]: how two people typing at once end up with the same text.- [[note-room]]: the Durable Object behind a note, its storage, and hibernation.- [[wire-protocol]]: the messages on the socket.- [[snapshots]]: the copy of every note in R2 every 100 versions, and how to read them.## Decisions- [[0001-single-sequencer-per-note]]: the room is the only place edits are ordered.- [[0002-drop-inserts-inside-concurrent-deletes]]: the one rule that keeps the transform small.- [[0003-snapshots-in-r2]]: history lives in R2, not in the room.## Guides- [[local-dev]]: run it on your machine, open two tabs, and watch the edits cross.
