Sorry about that... You should end up on a GitHub "Releases" page for each document.
In the section for the top-most release, you should see an "> Assets (3)" control. Click the arrow to open it. It should then list a PDF, a ZIP, and a '.tar.gz' document. You probably want the PDF, which you can read on the screen and/or print out. Download the document to your system by clicking on its link. -t -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
