# Offsets

> Understand how offsets let clients start reads, resume progress, and follow stream position safely.

An offset is a position within a stream. Clients use offsets to read from a specific point or resume where they left off.

* `offset=-1` means "from the very beginning."
* After each read or append, the server returns `Stream-Next-Offset`, the position to use for the next request.
* Offsets are opaque tokens. Clients should not construct them; always use the values returned by the server.
