text: Title: provide a way to init a .yaml file
  Body: 
  ### Description
  
  An initialized yaml file should be created automatically for the user. The user should not waste time creating a yaml file and copy pasting commands from igel's docs. 
  
  A better way would be to provide some command (e.g `igel init` or `igel start`) that will create a yaml file in the current working directory, where default commands are written.
