 In CliFx you define a command by making a new class that implements `ICommand` and annotating it with `CommandAttribute`. To specify properties that will be set from command line you need to annotate them with `CommandOptionAttribute`.
 
-Here's an example command that calculates logarithm. It has a name (`"log"`) which the user can specify to invoke it and it also contains two options, the source value (`"value"`/`'v'`) and logarithm base (`"base"`/`'b'`).

 ### Reporting errors

+You may have noticed that commands in CliFx don't return exit codes. This is by design as exit codes are considered a higher-level concern and thus handled by `CliApplication`, not by individual commands.
 
-Commands can report execution failure simply by throwing exceptions just like any other C# code. When an exception is thrown, `CliApplication` will catch it, print the error, and return a non-zero exit code to the calling process.

 If you want to communicate a specific error through exit code, you can throw an instance of `CommandException` which takes exit code as a constructor parameter.
