+Regression tests for recovery and replication
+=============================================
+
+This directory contains a test suite for recovery and replication,
+testing mainly the interactions of recovery.conf with cluster
+instances by providing a simple set of routines that can be used
+to define a custom cluster for a test, including backup, archiving,
+and streaming configuration.
+
+Running the tests
+=================
+
+ make check
+
+NOTE: This creates a temporary installation, and some tests may
+create one or multiple nodes, be they master or standby(s) for the
+purpose of the tests.
+
+NOTE: This requires the --enable-tap-tests argument to configure.
