macOS, and Linux (RPM) are available from

on the Nmap.org website.

Questions and suggestions may be sent to
the Nmap-dev mailing list.

Installing
----------
Ideally, you should be able to just type:

./configure
make
make install

For far more in-depth compilation, installation, and removal notes, read the
Nmap Install Guide on Nmap.org.

Using Nmap
----------
Nmap has a lot of features, but getting started is as easy as running nmap
scanme.nmap.org. Running nmap without any parameters will give a helpful
list of the most common options, which are discussed in depth in the man
page. Users who prefer a graphical interface
can use the included Zenmap front-end.

Contributing
------------
Information about filing bug reports and contributing to the Nmap project can
be found in the HACKING and CONTRIBUTING.md
files.
