How to install and run the Nmap program through Cygwin in Windows?

Question

I'm trying to get Cygwin to show what ports my laptop has open but when I try to run it, it says the command isn't found.

This is the command I'm trying: nmap -v -A <<IP address>>

This blog post has some useful info about how to get this working. Have copied it below in case it ever goes away:

1. Download nmap
2. Install nmap “self-installer” .exe and install Npcap when asked by the Nmap installer.
3. Note: An alternative of adding the path to the ~/.bashrc file is suggested in the comments. Cygwin: add to ~/.bash_profile: alias nmap="/cygdrive/c/Program\ Files\ \(x86\)/Nmap/nmap.exe". Note the \ and \( are vital for Cygwin shell to interpret the command correctly.
4. Open a new Cygwin window to start using nmap
