+
+==== Replication delay
+
+The `replication_delay` property allows test scenario steps to wait for that many seconds, prior to
+expecting a done replication. Its default is `15` seconds and can be set using another value:
+
+* `-Dcom.google.gerrit.scenarios.replication_delay=15`
+
+There is a short time buffer added to this property. Now, the replication starts after replication
+plugin's own `replicationDelay`, in seconds, and typically takes some more seconds to complete.
+That whole replication time depends on the system under test. Therefore, this property here should
+be set to a value high enough, so that the test checks for a done replication at the right time.
+
+==== Automatic properties
+
+The link:#_input_file[example keywords,role=external,window=_blank] also include `_PROJECT`,
+prefixed with an underscore, which means that its value gets automatically generated by the
+scenario. Any property setting for it is therefore not applicable. Its usage differs from the
+non-prefixed `PROJECT` keyword, in that sense. Using the latter instead in json files requires
+setting this `JAVA_OPTS` property:
+
+* `-Dcom.google.gerrit.scenarios.project=myOwnTestRepoProjectName`
+
+Other automatic keys may be used and implemented, always prefixed with an underscore that tells so.
+
+==== Plugin scenarios
+
+Plugin or otherwise non-core scenarios can also use such properties. The core java package
 `com.google.gerrit.scenarios` from the example above has to be replaced with the one under which
 those scenario classes are. Such extending scenarios can also add extension-specific properties.
