## Scope

By default, ERTS is only guaranteed to be compatible with other Erlang/OTP components from the same release as ERTS itself.

For information on how to communicate with Erlang/OTP components from earlier releases, see the documentation of system flag +R in erl(1).

## Prerequisites

It is assumed that the reader is familiar with the Erlang programming language.
