These .hpkg files will create a new top-level menu item in the Deskbar, called Documentation.
Start by installing devdocs_main. It will give you enough to get started with and will give you easy access to the documentation of your installed packages, their manfiles, and the BeOS/Haiku API documentation. It also includes a few e-books, enough to get you started, whether you are developing in bash, yab, python, perl or C/C++.
Once you have settled on your favourite language, you can install one of the more specialized packages. These will provide you with a LOT more e-books.
What you will need: The e-books are mostly in PDF format, but some are in HTML. You will need a browser (WebPositive is fine) and you will have to have a PDF reader of some kind (BePDF is fine, but there are others). The e-books will open in your default web browser or PDF program.
If you have any of my older devdocs packages installed (possibly from BeShare), please uninstall them. To help with this, I've harmonized all these packages to a "-11" package version number. Updates will increment from there.
