Hello 

In case you want to help Pharo, here is attached the latest version of the Pharo by Example book chapter.
The authors thanks the sponsoring of ESUG because updating a book is not just changing 5.0 into 8.0.

You can send PRs at 
https://github.com/SquareBracketAssociates/PharoByExample80

The full pdf is available at

If you want to support this effort:
- you can sponsor the book - you can get your logo on the book cover and be explicitly mentioned. 
The money will be split equally among the co-authors.

- you can sponsor me directly:
