I like the idea of the Commander library 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 

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
