Hi,

I like the idea of the Commander library 
https://github.com/dionisiydk/Commander 
<https://github.com/dionisiydk/Commander> 
I am trying to understand how to use it, but I struggle to understand it as 
documentation includes quiete complex examples: 
https://ci.inria.fr/pharo-contribution/view/Books/job/PharoBookWorkInProgress/lastSuccessfulBuild/artifact/book-result/Commander/Commander.html
 
<https://ci.inria.fr/pharo-contribution/view/Books/job/PharoBookWorkInProgress/lastSuccessfulBuild/artifact/book-result/Commander/Commander.html>
 

I believe that it would be useful to have a tutorial that shows:

1. create a command CmdOne including methods,
2. create a activator ActOne including methods,
3. create a context CtxOne including methods,
4. execute <I do not know what> and you obtain a collection with one item 
(CmdOne instance?)
5. create command CmdTwo with some methods
6. execute <I do not know what> and you obtain a collection with two items

Then next section could describe how to make a UI on top of this.

Learning it by exploring Calypso is too complex, because it involves more 
objects and I actually do not see how to do the previous steps.

I will be happy to help with the documentation.
My question is: How can I proceed the mentioned steps?

Thanks,
Juraj
