pg_standby question

Hello

I am trying test pg_stand by. I used archive and restore commands via
README.pg_standby.

recovery finish with notice in log:

Trigger file : <not set>
Waiting for WAL file : /usr/local/pgsql/archive/000000010000000000000000

Restoring to... : pg_xlog/RECOVERYXLOG
Sleep interval : 5 seconds
Max wait interval : 0 forever

PANIC: could not locate a valid checkpoint record
LOG: startup process (PID 23521) was terminated by signal 6: Aborted

but all datase clusters was reinicialised before I starting. What is
correct sequence for building replication system?
