Puppy has a very useful doc directory.
However, to access it, you have to use a file manager and navigate to /usr/share/doc
To access, just left click on a file, to open and see, info inside.
Some of the Puppy specific info files:
home.htm ->opens in the browser with links to Puppy web sites.
forums.htm ->opens in the browser with links to Puppy forums.
index.htm ->the main Puppy help page.
/usr/share/doc has many other information and help files, usually accessed by the help in their respective programs.
But they also can be accessed by navigating to this doc directory.
