How to do "Shared Library Documentation"?

[thomas....@teamaol.com]

Using an own repository with Groovy code following the structure

as explained here: https://jenkins.io/doc/book/pipeline/shared-libraries/

I see how I can provide documentation (see foo.txt there) ...

...using HTML inside the .txt ....

However - also mentioned there - I can see the documentation

in the global variable reference only when the pipeline run has

been successful.

Is there no other way to provide documentation for somebody

who would like to build up documentation?

Where do I see documentation for classes I write under src?

Is there sombody who can provide a example project for a Groovy 

shared library doing also such documentation?

Kind Regards,

Thomas
