Missing docs: setting up replication slots for standbys - Mailing list pgsql-docs

Section 46.2.2 has this:

Note: PostgreSQL also has streaming replication slots (see Section
25.2.5), but they are used somewhat differently there.

Section 25.2.5 has this:

 You can avoid this by setting wal_keep_segments to a value large enough
to ensure that WAL segments are not recycled too early, or by
configuring a replication slot for the standby.

... however, absolutely nowhere is it explained how to configure a
replication slot for a streaming replica.  Is it, in fact, possible to
do so?
