+## Running KSQL
+
+KSQL supports various [modes of operation](concepts.md#modes-of-operation), including a standalone mode and a
+client-server mode.
+
+Additionally, you can also instruct KSQL to execute a single statement from the command line.
+The following example command runs the given `SELECT` statement and show the results in the terminal.  In this
+particular case, the query will run until 5 records have been found, and then terminate.
+
+```shell
+$ ksql-cli local --exec "SELECT * FROM pageviews LIMIT 5;"
