+# Native run example application
+
+`native_run_app` is a terminal client application (i.e., one providing the
+`mojo.terminal.TerminalClient` service) that allows native (Linux) applications
+to be run inside a Mojo ([Moterm](../../apps/moterm)) terminal. It does this by
+using the `native_support` service, which provides facilities to
+(programmatically) run native applications.
+
+See [//examples/moterm_example_app](../moterm_example_app) for an example of how
+it may be used.
