Reduce barriers to entry

[tortoise74]

I was looking for a requirements tool and came across rmtoo.
Installing with pip was easy.
However, there some hurdles to getting starting with it that could be improved.

• rmtoo --help - should mention that the documentation is available via man pages

The main website could provide one or more of:

• A quickstart guide
• online versions of the man pages
• some example input
• some example command lines

The requirements document PDF is on the page but not the source from which it was created.
I presume it is one or more of the files listed by:

pip show -f rmtoo

This also lists some documentation files installed somewhere.
To find them you need to know a lot about pip.
