 You can include another minicode file into your code. The code will connect and be executed immediately.
 
 ```mc
--> test/examples/hello_world.mc

+
+Just like when running regular minicode code, you can pass arguments to the command line, which will be available as ARG_1, ARG_2 and so on in the list
+
+If you specify a long arrow as a command, as in the example below, then the following code will be executed asynchronously.

 ```mc

+Точно также как и при запуске обычного миникод кода, вы можете передавать аргументы командой строки, который будут достпны как ARG_1, ARG_2 и так далее по списку

+Если указать длинную стрелочку в качестве команды, как на примере ниже, то сладеюущий код будет выполнятся асинхронно.
